+Version 5.1.2 -- 2007-12-26
+
+================================================================
+To use Unixbench:
+
+1. UnixBench from version 5.1 on has both system and graphics tests.
+   If you want to use the graphic tests, edit the Makefile and make sure
+   that the line "GRAPHIC_TESTS = defined" is not commented out; then check
+   that the "GL_LIBS" definition is OK for your system.  Also make sure
+   that the "x11perf" command is on your search path.
+
+   If you don't want the graphics tests, then comment out the
+   "GRAPHIC_TESTS = defined" line.  Note: comment it out, don't
+   set it to anything.
+
+2. Do "make".
+
+3. Do "Run" to run the system test; "Run graphics" to run the graphics
+   tests; "Run gindex" to run both.
+
+You will need perl, as Run is written in perl.
+
+For more information on using the tests, read "USAGE".
+
+For information on adding tests into the benchmark, see "WRITING_TESTS".
+
+
+===================== RELEASE NOTES =====================================
+
+========================  Dec 07 ==========================
+
+v5.1.2
+
+One big fix: if unixbench is installed in a directory whose pathname contains
+a space, it should now run (previously it failed).
+
+To avoid possible clashes, the environment variables unixbench uses are now
+prefixed with "UB_".  These are all optional, and for most people will be
+completely unnecessary, but if you want you can set these:
+
+    UB_BINDIR      Directory where the test programs live.
+    UB_TMPDIR      Temp directory, for temp files.
+    UB_RESULTDIR   Directory to put results in.
+    UB_TESTDIR     Directory where the tests are executed.
+
+And a couple of tiny fixes:
+* In pgms/tst.sh, changed "sort -n +1" to "sort -n -k 1"
+* In Makefile, made it clearer that GRAPHIC_TESTS should be commented
+  out (not set to 0) to disable graphics
+Thanks to nordi for pointing these out.

+
+========================  Oct 07 ==========================
+
+v5.1.1
+
+It turns out that the setting of LANG is crucial to the results.  This
+explains why people in different regions were seeing odd results, and also
+why runlevel 1 produced odd results -- runlevel 1 doesn't set LANG, and
+hence reverts to ASCII, whereas most people use a UTF-8 encoding, which is
+much slower in some tests (eg. shell tests).
+
+So now we manually set LANG to "en_US.utf8", which is configured with the
+variable "$language".  Don't change this if you want to share your results.
+We also report the language settings in use.
+
+See "The Language Setting" in USAGE for more info.  Thanks to nordi for
+pointing out the LANG issue.
+
+I also added the "grep" and "sysexec" tests.  These are non-index tests,
+and "grep" uses the system's grep, so it's not much use for comparing
+different systems.  But some folks on the OpenSuSE list have been finding
+these useful.  They aren't in any of the main test groups; do "Run grep
+sysexec" to run them.
+
+Index Changes
+-------------
+
+The setting of LANG will affect consistency with systems where this is
+not the default value.  However, it should produce more consistent results
+in future.

+
+
+========================  Oct 07 ==========================
+
+v5.1
+
+The major new feature in this version is the addition of graphical
+benchmarks.  Since these may not compile on all systems, you can enable/
+disable them with the GRAPHIC_TESTS variable in the Makefile.
+
+As before, each test is run for 3 or 10 iterations.  However, we now discard
+the worst 1/3 of the scores before averaging the remainder.  The logic is
+that a glitch in the system (background process waking up, for example) may
+make one or two runs go slow, so let's discard those.  Hopefully this will
+produce more consistent and repeatable results.  Check the log file
+for a test run to see the discarded scores.
+
+Made the tests compile and run on x86-64/Linux (fixed an execl bug passing
+int instead of pointer).
+
+Also fixed some general bugs.
+
+Thanks to Stefan Esser for help and testing / bug reporting.
+
+Index Changes
+-------------
+
+The tests are now divided into categories, and each category generates
+its own index.  This keeps the graphics test results separate from
+the system tests.
+
+The "graphics" test and corresponding index are new.
+
+The "discard the worst scores" strategy should produce slightly higher
+test scores, but at least they should (hopefully!) be more consistent.
+The scores should not be higher than the best scores you would have got
+with 5.0, so this should not be a huge consistency issue.

+
+========================  Sep 07 ==========================
+
+v5.0
+
+All the work I've done on this release is Linux-based, because that's
+the only Unix I have access to.  I've tried to make it more OS-agnostic
+if anything; for example, it no longer has to figure out the format reported
+by /usr/bin/time.  However, it's possible that portability has been damaged.
+If anyone wants to fix this, please feel free to mail me patches.
+
+In particular, the analysis of the system's CPUs is done via /proc/cpuinfo.
+For systems which don't have this, please make appropriate changes in
+getCpuInfo() and getSystemInfo().
+
+The big change has been to make the tests multi-CPU aware.  See the
+"Multiple CPUs" section in "USAGE" for details.  Other changes:
+
+* Completely rewrote Run in Perl; drastically simplified the way data is
+  processed.  The confusing system of interlocking shell and awk scripts is
+  now just one script.  Various intermediate files used to store and process
+  results are now replaced by Perl data structures internal to the script.
+
+* Removed from the index runs file system read and write tests which were
+  ignored for the index and wasted about 10 minutes per run (see fstime.c).
+  The read and write tests can now be selected individually.  Made fstime.c
+  take parameters, so we no longer need to build 3 versions of it.
+
+* Made the output file names unique; they are built from
+  hostname-date-sequence.
+
+* Worked on result reporting, error handling, and logging.  See TESTS.
+  We now generate both text and HTML reports.
+
+* Removed some obsolete files.
+
+Index Changes
+-------------
+
+The index is still based on David Niemi's SPARCstation 20-61 (rated at 10.0),
+and the intention in the changes I've made has been to keep the tests
+unchanged, in order to maintain consistency with old result sets.
+
+However, the following changes have been made to the index:
+
+* The Pipe-based Context Switching test (context1) was being dropped
+  from the index report in v4.1.0 due to a bug; I've put it back in.
+
+* I've added shell1 to the index, to get a measure of how the shell tests
+  scale with multiple CPUs (shell8 already exercises all the CPUs, even
+  in single-copy mode).  I made up the baseline score for this by
+  extrapolation.
+
+Both of these test can be dropped, if you wish, by editing the "TEST
+SPECIFICATIONS" section of Run.

+
+v4.1.0
+
+Double precision Whetstone put in place instead of the old "double" benchmark.
+
+Removal of some obsolete files.
+
+"system" suite adds shell8.
+
+perlbench and poll added as "exhibition" (non-index) benchmarks.
+
+Incorporates several suggestions by Andre Derrick Balsa <andrewbalsa@usa.net>
+
+Code cleanups to reduce compiler warnings by David C Niemi <niemi@tux.org>
+and Andy Kahn <kahn@zk3.dec.com>; Digital Unix options by Andy Kahn.

+========================  Jun 97 ==========================
+
+v4.0.1
+
+Minor change to fstime.c to fix overflow problems on fast machines.  Counting
+is now done in units of 256 (smallest BUFSIZE) and unsigned longs are used,
+giving another 23 dB or so of headroom ;^)  Results should be virtually
+identical aside from very small rounding errors.
+
+========================  Dec 95 ==========================
+
+v4.0
+
+Byte no longer seems to have anything to do with this benchmark, and I was
+unable to reach any of the original authors; so I have taken it upon myself
+to clean it up.
+
+This is version 4.  Major assumptions made in these benchmarks have changed
+since they were written, but they are nonetheless popular (particularly for
+measuring hardware for Linux).  Some changes made:
+
+-	The biggest change is to put a lot more operating system-oriented
+	tests into the index.  I experimented for a while with a decibel-like
+	logarithmic scale, but finally settled on using a geometric mean for
+	the final index (the individual scores are a normalized, and their
+	logs are averaged; the resulting value is exponentiated).
+
+	"George", certain SPARCstation 20-61 with 128 MB RAM, a SPARC Storage
+	Array, and Solaris 2.3 is my new baseline; it is rated at 10.0 in each
+	of the index scores for a final score of 10.0.
+
+	Overall I find the geometric averaging is a big improvement for
+	avoiding the skew that was once possible (e.g. a Pentium-75 which got
+	40 on the buggy version of fstime, such that fstime accounted for over
+	half of its total score and hence wildly skewed its average).
+
+	I also expect that the new numbers look different enough from the old
+	ones that no one is too likely to casually mistake them for each other.
+
+	I am finding new SPARCs running Solaris 2.4 getting about 15-20, and
+	my 486 DX2-66 Compaq running Linux 1.3.45 got a 9.1.  It got
+	understandably poor scores on CPU and FPU benchmarks (a horrible
+	1.8 on "double" and 1.3 on "fsdisk"); but made up for it by averaging
+	over 20 on the OS-oriented benchmarks.  The Pentium-75 running
+	Linux gets about 20 (and it *still* runs Windows 3.1 slowly.  Oh well).
+
+-	It is difficult to get a modern compiler to even consider making
+	dhry2 without registers, short of turning off *all* optimizations.
+	This is also not a terribly meaningful test, even if it were possible,
+	as noone compiles without registers nowadays.  Replaced this benchmark
+	with dhry2reg in the index, and dropped it out of usage in general as
+	it is so hard to make a legitimate one.
+
+-	fstime: this had some bugs when compiled on modern systems which return
+	the number of bytes read/written for read(2)/write(2) calls.  The code
+	assumed that a negative return code was given for EOF, but most modern
+	systems return 0 (certainly on SunOS 4, Solaris2, and Linux, which is
+	what counts for me).  The old code yielded wildly inflated read scores,
+	would eat up tens of MB of disk space on fast systems, and yielded
+	roughly 50% lower than normal copy scores than it should have.
+
+	Also, it counted partial blocks *fully*; made it count the proportional
+	part of the block which was actually finished.
+
+	Made bigger and smaller variants of fstime which are designed to beat
+	up the disk I/O and the buffer cache, respectively.  Adjusted the
+	sleeps so that they are short for short benchmarks.
+
+-	Instead of 1,2,4, and 8-shell benchmarks, went to 1, 8, and 16 to
+	give a broader range of information (and to run 1 fewer test).
+	The only real problem with this is that not many iterations get
+	done with 16 at a time on slow systems, so there are some significant
+	rounding errors; 8 therefore still used for the benchmark.  There is
+	also the problem that the last (uncompleted) loop is counted as a full
+	loop, so it is impossible to score below 1.0 lpm (which gave my laptop
+	a break).  Probably redesigning Shell to do each loop a bit more
+	quickly (but with less intensity) would be a good idea.
+
+	This benchmark appears to be very heavily influenced by the speed
+	of the loader, by which shell is being used as /bin/sh, and by how
+	well-compiled some of the common shell utilities like grep, sed, and
+	sort are.  With a consistent tool set it is also a good indicator of
+	the bandwidth between main memory and the CPU (e.g. Pentia score about
+	twice as high as 486es due to their 64-bit bus).  Small, sometimes
+	broken shells like "ash-linux" do particularly well here, while big,
+	robust shells like bash do not.
+
+-	"dc" is a somewhat iffy benchmark, because there are two versions of
+	it floating around, one being small, very fast, and buggy, and one
+	being more correct but slow.  It was never in the index anyway.
+
+-	Execl is a somewhat troubling benchmark in that it yields much higher
+	scores if compiled statically.  I frown on this practice because it
+	distorts the scores away from reflecting how programs are really used
+	(i.e. dynamically linked).
+
+-	Arithoh is really more an indicator of the compiler quality than of
+	the computer itself.  For example, GCC 2.7.x with -O2 and a few extra
+	options optimizes much of it away, resulting in about a 1200% boost
+	to the score.  Clearly not a good one for the index.
+
+I am still a bit unhappy with the variance in some of the benchmarks, most
+notably the fstime suite; and with how long it takes to run.  But I think
+it gets significantly more reliable results than the older version in less
+time.
+
+If anyone has ideas on how to make these benchmarks faster, lower-variance,
+or more meaningful; or has nice, new, portable benchmarks to add, don't
+hesitate to e-mail me.

+========================  May 91 ==========================
+This is version 3. This set of programs should be able to determine if
+your system is BSD or SysV. (It uses the output format of time (1)
+to see. If you have any problems, contact me (by email,
+preferably): ben@bytepb.byte.com
+
+---
+
+The document doc/bench.doc describes the basic flow of the
+benchmark system. The document doc/bench3.doc describes the major
+changes in design of this version. As a user of the benchmarks,
+you should understand some of the methods that have been
+implemented to generate loop counts:
+
+Tests that are compiled C code:
+  The function wake_me(second, func) is included (from the file
+timeit.c). This function uses signal and alarm to set a countdown
+for the time request by the benchmark administration script
+(Run). As soon as the clock is started, the test is run with a
+counter keeping track of the number of loops that the test makes.
+When alarm sends its signal, the loop counter value is sent to stderr
+and the program terminates. Since the time resolution, signal
+trapping and other factors don't insure that the test is for the
+precise time that was requested, the test program is also run
+from the time (1) command. The real time value returned from time
+(1) is what is used in calculating the number of loops per second
+(or minute, depending on the test).  As is obvious, there is some
+overhead time that is not taken into account, therefore the
+number of loops per second is not absolute. The overhead of the
+test starting and stopping and the signal and alarm calls is
+common to the overhead of real applications. If a program loads
+quickly, the number of loops per second increases; a phenomenon
+that favors systems that can load programs quickly. (Setting the
+sticky bit of the test programs is not considered fair play.)
+
+Test that use existing UNIX programs or shell scripts:
+  The concept is the same as that of compiled tests, except the
+alarm and signal are contained in separate compiled program,
+looper (source is looper.c). Looper uses an execvp to invoke the
+test with its arguments. Here, the overhead includes the
+invocation and execution of looper.
+
+--
+
+The index numbers are generated from a baseline file that is in
+pgms/index.base. You can put tests that you wish in this file.
+All you need to do is take the results/log file from your
+baseline machine, edit out the comment and blank lines, and sort
+the result (vi/ex command: 1,$!sort). The sort in necessary
+because the process of generating the index report uses join (1).
+You can regenerate the reports by running "make report."
+

+
+========================= Jan 90 =============================
+Tom Yager has joined the effort here at BYTE; he is responsible
+for many refinements in the UNIX benchmarks.
+
+The memory access tests have been deleted from the benchmarks.
+The file access tests have been reversed so that the test is run
+for a fixed time. The amount of data transfered (written, read,
+and copied) is the variable. !WARNING! This test can eat up a
+large hunk of disk space.
+
+The initial line of all shell scripts has been changed from the
+SCO and XENIX form (:) to the more standard form "#! /bin/sh".
+But different systems handle shell switching differently. Check
+the documentation on your system and find out how you are
+supposed to do it. Or, simpler yet, just run the benchmarks from
+the Bourne shell. (You may need to set SHELL=/bin/sh as well.)
+
+The options to Run have not been checked in a while. They may no
+longer function. Next time, I'll get back on them. There needs to
+be another option added (next time) that halts testing between
+each test. !WARNING! Some systems have caches that are not getting flushed
+before the next test or iteration is run. This can cause
+erroneous values.
+
+========================= Sept 89 =============================
+The database (db) programs now have a tuneable message queue space.
+queue space. The default set in the Run script is 1024 bytes.
+Other major changes are in the format of the times. We now show
+Arithmetic and Geometric mean and standard deviation for User
+Time, System Time, and Real Time. Generally, in reporting, we
+plan on using the Real Time values with the benchs run with one
+active user (the bench user). Comments and arguments are requested.

+Running the Tests
+=================
+
+All the tests are executed using the "Run" script in the top-level directory.
+
+The simplest way to generate results is with the commmand:
+    ./Run
+
+This will run a standard "index" test (see "The BYTE Index" below), and
+save the report in the "results" directory, with a filename like
+    hostname-2007-09-23-01
+An HTML version is also saved.
+
+If you want to generate both the basic system index and the graphics index,
+then do:
+    ./Run gindex
+
+If your system has more than one CPU, the tests will be run twice -- once
+with a single copy of each test running at once, and once with N copies,
+where N is the number of CPUs.  Some categories of tests, however (currently
+the graphics tests) will only run with a single copy.
+
+Since the tests are based on constant time (variable work), a "system"
+run usually takes about 29 minutes; the "graphics" part about 18 minutes.
+A "gindex" run on a dual-core machine will do 2 "system" passes (single-
+and dual-processing) and one "graphics" run, for a total around one and
+a quarter hours.
+
+============================================================================
+
+Detailed Usage
+==============
+
+The Run script takes a number of options which you can use to customise a
+test, and you can specify the names of the tests to run.  The full usage
+is:
+
+    Run [ -q | -v ] [-i <n> ] [-c <n> [-c <n> ...]] [test ...]
+
+The option flags are:
+
+  -q            Run in quiet mode.
+  -v            Run in verbose mode.
+  -i <count>    Run <count> iterations for each test -- slower tests
+                use <count> / 3, but at least 1.  Defaults to 10 (3 for
+                slow tests).
+  -c <n>        Run <n> copies of each test in parallel.
+
+The -c option can be given multiple times; for example:
+
+    ./Run -c 1 -c 4
+
+will run a single-streamed pass, then a 4-streamed pass.  Note that some
+tests (currently the graphics tests) will only run in a single-streamed pass.
+
+The remaining non-flag arguments are taken to be the names of tests to run.
+The default is to run "index".  See "Tests" below.
+
+When running the tests, I do *not* recommend switching to single-user mode
+("init 1").  This seems to change the results in ways I don't understand,
+and it's not realistic (unless your system will actually be running in this
+mode, of course).  However, if using a windowing system, you may want to
+switch to a minimal window setup (for example, log in to a "twm" session),
+so that randomly-churning background processes don't randomise the results
+too much.  This is particularly true for the graphics tests.
+
+
+============================================================================
+
+Tests

+scores (see "The BYTE Index" below) the results for each category are
+produced separately.  The categories are:

+
+============================================================================
+
+The BYTE Index
+==============
+
+The purpose of this test is to provide a basic indicator of the performance
+of a Unix-like system; hence, multiple tests are used to test various
+aspects of the system's performance.  These test results are then compared
+to the scores from a baseline system to produce an index value, which is
+generally easier to handle than the raw sores.  The entire set of index
+values is then combined to make an overall index for the system.
+
+Since 1995, the baseline system has been "George", a SPARCstation 20-61
+with 128 MB RAM, a SPARC Storage Array, and Solaris 2.3, whose ratings
+were set at 10.0.  (So a system which scores 520 is 52 times faster than
+this machine.)  Since the numbers are really only useful in a relative
+sense, there's no particular reason to update the base system, so for the
+sake of consistency it's probably best to leave it alone.  George's scores
+are in the file "pgms/index.base"; this file is used to calculate the
+index scores for any particular run.
+
+Over the years, various changes have been made to the set of tests in the
+index.  Although there is a desire for a consistent baseline, various tests
+have been determined to be misleading, and have been removed; and a few
+alternatives have been added.  These changes are detailed in the README,
+and should be born in mind when looking at old scores.
+
+A number of tests are included in the benchmark suite which are not part of
+the index, for various reasons; these tests can of course be run manually.
+See "Tests" above.
+
+
+============================================================================
+
+Graphics Tests
+==============
+
+As of version 5.1, UnixBench now contains some graphics benchmarks.  These
+are intended to give a rough idea of the general graphics performance of
+a system.
+
+The graphics tests are in categories "2d" and "3d", so the index scores
+for these tests are separate from the basic system index.  This seems
+like a sensible division, since the graphics performance of a system
+depends largely on the graphics adaptor.
+
+The tests currently consist of some 2D "x11perf" tests and "ubgears".
+
+* The 2D tests are a selection of the x11perf tests, using the host
+  system's x11perf command (which must be installed and in the search
+  path).  Only a few of the x11perf tests are used, in the interests
+  of completing a test run in a reasonable time; if you want to do
+  detailed diagnosis of an X server or graphics chip, then use x11perf
+  directly.
+
+* The 3D test is "ubgears", a modified version of the familiar "glxgears".
+  This version runs for 5 seconds to "warm up", then performs a timed
+  run and displays the average frames-per-second.
+
+On multi-CPU systems, the graphics tests will only run in single-processing
+mode.  This is because the meaning of running two copies of a test at once
+is dubious; and the test windows tend to overlay each other, meaning that
+the window behind isn't actually doing any work.
+
+
+============================================================================
+
+Multiple CPUs
+=============
+
+If your system has multiple CPUs, the default behaviour is to run the selected
+tests twice -- once with one copy of each test program running at a time,
+and once with N copies, where N is the number of CPUs.  (You can override
+this with the "-c" option; see "Detailed Usage" above.)  This is designed to
+allow you to assess:
+
+ - the performance of your system when running a single task
+ - the performance of your system when running multiple tasks
+ - the gain from your system's implementation of parallel processing
+
+The results, however, need to be handled with care.  Here are the results
+of two runs on a dual-processor system, one in single-processing mode, one
+dual-processing:
+
+  Test                    Single     Dual   Gain
+  --------------------    ------   ------   ----
+  Dhrystone 2              562.5   1110.3    97%
+  Double Whetstone         320.0    640.4   100%
+  Execl Throughput         450.4    880.3    95%
+  File Copy 1024           759.4    595.9   -22%
+  File Copy 256            535.8    438.8   -18%
+  File Copy 4096          1261.8   1043.4   -17%
+  Pipe Throughput          481.0    979.3   104%
+  Pipe-based Switching     326.8   1229.0   276%
+  Process Creation         917.2   1714.1    87%
+  Shell Scripts (1)       1064.9   1566.3    47%
+  Shell Scripts (8)       1567.7   1709.9     9%
+  System Call Overhead     944.2   1445.5    53%
+  --------------------    ------   ------   ----
+  Index Score:             678.2   1026.2    51%
+
+As expected, the heavily CPU-dependent tasks -- dhrystone, whetstone,
+execl, pipe throughput, process creation -- show close to 100% gain when
+running 2 copies in parallel.
+
+The Pipe-based Context Switching test measures context switching overhead
+by sending messages back and forth between 2 processes.  I don't know why
+it shows such a huge gain with 2 copies (ie. 4 processes total) running,
+but it seems to be consistent on my system.  I think this may be an issue
+with the SMP implementation.
+
+The System Call Overhead shows a lesser gain, presumably because it uses a
+lot of CPU time in single-threaded kernel code.  The shell scripts test with
+8 concurrent processes shows no gain -- because the test itself runs 8
+scripts in parallel, it's already using both CPUs, even when the benchmark
+is run in single-stream mode.  The same test with one process per copy
+shows a real gain.
+
+The filesystem throughput tests show a loss, instead of a gain, when
+multi-processing.  That there's no gain is to be expected, since the tests
+are presumably constrained by the throughput of the I/O subsystem and the
+disk drive itself; the drop in performance is presumably down to the
+increased contention for resources, and perhaps greater disk head movement.
+
+So what tests should you use, how many copies should you run, and how should
+you interpret the results?  Well, that's up to you, since it depends on
+what it is you're trying to measure.
+
+Implementation
+--------------
+
+The multi-processing mode is implemented at the level of test iterations.
+During each iteration of a test, N slave processes are started using fork().
+Each of these slaves executes the test program using fork() and exec(),
+reads and stores the entire output, times the run, and prints all the
+results to a pipe.  The Run script reads the pipes for each of the slaves
+in turn to get the results and times.  The scores are added, and the times
+averaged.
+
+The result is that each test program has N copies running at once.  They
+should all finish at around the same time, since they run for constant time.
+
+If a test program itself starts off K multiple processes (as with the shell8
+test), then the effect will be that there are N * K processes running at
+once.  This is probably not very useful for testing multi-CPU performance.
+
+
+============================================================================
+
+The Language Setting
+====================
+
+The $LANG environment variable determines how programs abnd library
+routines interpret text.  This can have a big impact on the test results.
+
+If $LANG is set to POSIX, or is left unset, text is treated as ASCII; if
+it is set to en_US.UTF-8, foir example, then text is treated as being
+encoded in UTF-8, which is more complex and therefore slower.  Setting
+it to other languages can have varying results.
+
+To ensure consistency between test runs, the Run script now (as of version
+5.1.1) sets $LANG to "en_US.utf8".
+
+This setting which is configured with the variable "$language".  You
+should not change this if you want to share your results to allow
+comparisons between systems; however, you may want to change it to see
+how different language settings affect performance.
+
+Each test report now includes the language settings in use.  The reported
+language is what is set in $LANG, and is not necessarily supported by the
+system; but we also report the character mapping and collation order which
+are actually in use (as reported by "locale").

+============================================================================
+
+Interpreting the Results
+========================
+
+Interpreting the results of these tests is tricky, and totally depends on
+what you're trying to measure.
+
+For example, are you trying to measure how fast your CPU is?  Or how good
+your compiler is?  Because these tests are all recompiled using your host
+system's compiler, the performance of the compiler will inevitably impact
+the performance of the tests.  Is this a problem?  If you're choosing a
+system, you probably care about its overall speed, which may well depend
+on how good its compiler is; so including that in the test results may be
+the right answer.  But you may want to ensure that the right compiler is
+used to build the tests.
+
+On the other hand, with the vast majority of Unix systems being x86 / PC
+compatibles, running Linux and the GNU C compiler, the results will tend
+to be more dependent on the hardware; but the versions of the compiler and
+OS can make a big difference.  (I measured a 50% gain between SUSE 10.1
+and OpenSUSE 10.2 on the same machine.)  So you may want to make sure that
+all your test systems are running the same version of the OS; or at least
+publish the OS and compuiler versions with your results.  Then again, it may
+be compiler performance that you're interested in.
+
+The C test is very dubious -- it tests the speed of compilation.  If you're
+running the exact same compiler on each system, OK; but otherwise, the
+results should probably be discarded.  A slower compilation doesn't say
+anything about the speed of your system, since the compiler may simply be
+spending more time to super-optimise the code, which would actually make it
+faster.
+
+This will be particularly true on architectures like IA-64 (Itanium etc.)
+where the compiler spends huge amounts of effort scheduling instructions
+to run in parallel, with a resultant significant gain in execution speed.
+
+Some tests are even more dubious in terms of host-dependency -- for example,
+the "dc" test uses the host's version of dc (a calculator program).  The
+version of this which is available can make a huge difference to the score,
+which is why it's not in the index group.  Read through the release notes
+for more on these kinds of issues.
+
+Another age-old issue is that of the benchmarks being too trivial to be
+meaningful.  With compilers getting ever smarter, and performing more
+wide-ranging flow path analyses, the danger of parts of the benchmarks
+simply being optimised out of existance is always present.
+
+All in all, the "index" and "gindex" tests (see above) are designed to
+give a reasonable measure of overall system performance; but the results
+of any test run should always be used with care.

+Writing a Test
+==============
+
+Writing a test program is pretty easy.  Basically, a test is configured via
+a monster array in the Run script, which specifics (among other things) the
+program to execute and the parameters to pass it.
+
+The test itself is simply a program which is given the optional parameters
+on the command line, and produces logging data on stdout and its results on
+stderr.
+
+
+============================================================================
+
+Test Configuration
+==================
+
+In Run, all tests are named in the "$testList" array.  This names the
+individual tests, and also sets up aliases for groups of tests, eg. "index".
+
+The test specifications are in the "$testParams" array.  This contains the
+details of each individual test as a hash.  The fields in the hash are:
+
+ * "logmsg": the full name to display for this test.
+ * "cat": the category this test belongs to; must be configured
+   in $testCats.
+ * "prog": the name of the program to execute; defaults to the name of
+   the benchmark.
+ * "repeat": number of passes to run; either 'short' (the default),
+   'long', or 'single'.   For 'short' and 'long', the actual numbers of
+   passes are given by $shortIterCount and $longIterCount, which are
+   configured at the top of the script or by the "-i" flag.  'single'
+   means just run one pass; this should be used for test which do their
+   own multi-pass handling internally.
+ * "stdout": non-0 to add the test's stdout to the log file; defaults to 1.
+   Set to 0 for tests that are too wordy.
+ * "stdin": name of a file to send to the program's stdin; default null.
+ * "options": options to be put on the program's command line; default null.
+
+
+============================================================================
+
+Output Format
+=============
+
+The results on stderr take the form of a line header and fields, separated
+by "|" characters.  A result line can be one of:
+
+    COUNT|score|timebase|label
+    TIME|seconds
+    ERROR|message
+
+Any other text on stderr is treated as if it were:
+
+    ERROR|text
+
+Any output to stdout is placed in a log file, and can be used for debugging.
+
+COUNT
+-----
+
+The COUNT line is the line used to report a test score.
+
+ * "score" is the result, typically the number of loops performed during
+   the run
+ * "timebase" is the time base used for the final report to the user.  A
+   value of 1 reports the score as is; a value of 60, for example, divides
+   the time taken by 60 to get loops per minute.  Atimebase of zero indicates
+   that the score is already a rate, ie. a count of things per second.
+ * "label" is the label to use for the score; like "lps" (loops per
+   second), etc.
+
+TIME
+----
+
+The TIME line is optionally used to report the time taken.  The Run script
+normally measures this, but if your test has signifant overhead outside the
+actual test loop, you should use TIME to report the time taken for the actual
+test.  The argument is the time in seconds in floating-point.
+
+ERROR
+-----
+
+The argument is an error message; this will abort the benchmarking run and
+display the message.
+
+Any output to stderr which is not a formatted line will be treated as an
+error message, so use of ERROR is optional.
+
+
+============================================================================
+
+Test Examples
+=============
+
+Iteration Count
+---------------
+
+The simplest thing is to count the number of loops executed in a given time;
+see eg. arith.c.  The utlilty functions in timeit.c can be used to implement
+the fixed time interval, which is generally passed in on the command line.
+
+The result is reported simply as the number of iterations completed:
+
+        fprintf(stderr,"COUNT|%lu|1|lps\n", iterations);
+
+The bnenchmark framework will measure the time taken itself.  If the test
+code has significant overhead (eg. a "pump-priming" pass), then you should
+explicitly report the time taken for the test by adding a line like this:
+
+        fprintf(stderr, "TIME|%.1f\n", seconds);
+
+If you want results reported as loops per minute, then set timebase to 60:
+
+        fprintf(stderr,"COUNT|%lu|60|lpm\n", iterations);
+
+Note that this only affects the final report; all times passed to or
+from the test are still in seconds.
+
+Rate
+----
+
+The other technique is to calculate the rate (things per second) in the test,
+and report that directly.  To do this, just set timebase to 0:
+
+        fprintf(stderr, "COUNT|%ld|0|KBps\n", kbytes_per_sec);
+
+Again, you can use TIME to explicitly report the time taken:
+
+        fprintf(stderr, "TIME|%.1f\n", end - start);
+
+but this isn't so important since you've already calculated the rate.

+ *
+ ***************************************************************************
+ *
+ *  History:    This version C/2.1 has been made for two reasons:
+ *
+ *              1) There is an obvious need for a common C version of
+ *              Dhrystone, since C is at present the most popular system
+ *              programming language for the class of processors
+ *              (microcomputers, minicomputers) where Dhrystone is used most.
+ *              There should be, as far as possible, only one C version of
+ *              Dhrystone such that results can be compared without
+ *              restrictions. In the past, the C versions distributed
+ *              by Rick Richardson (Version 1.1) and by Reinhold Weicker
+ *              had small (though not significant) differences.
+ *
+ *              2) As far as it is possible without changes to the Dhrystone
+ *              statistics, optimizing compilers should be prevented from
+ *              removing significant statements.
+ *
+ *              This C version has been developed in cooperation with
+ *              Rick Richardson (Tinton Falls, NJ), it incorporates many
+ *              ideas from the "Version 1.1" distributed previously by
+ *              him over the UNIX network Usenet.
+ *              I also thank Chaim Benedelac (National Semiconductor),
+ *              David Ditzel (SUN), Earl Killian and John Mashey (MIPS),
+ *              Alan Smith and Rafael Saavedra-Barrera (UC at Berkeley)
+ *              for their help with comments on earlier versions of the
+ *              benchmark.
+ *
+ *  Changes:    In the initialization part, this version follows mostly
+ *              Rick Richardson's version distributed via Usenet, not the
+ *              version distributed earlier via floppy disk by Reinhold Weicker.
+ *              As a concession to older compilers, names have been made
+ *              unique within the first 8 characters.
+ *              Inside the measurement loop, this version follows the
+ *              version previously distributed by Reinhold Weicker.
+ *
+ *              At several places in the benchmark, code has been added,
+ *              but within the measurement loop only in branches that 
+ *              are not executed. The intention is that optimizing compilers
+ *              should be prevented from moving code out of the measurement
+ *              loop, or from removing code altogether. Since the statements
+ *              that are executed within the measurement loop have NOT been
+ *              changed, the numbers defining the "Dhrystone distribution"
+ *              (distribution of statements, operand types and locality)
+ *              still hold. Except for sophisticated optimizing compilers,
+ *              execution times for this version should be the same as
+ *              for previous versions.
+ *              
+ *              Since it has proven difficult to subtract the time for the
+ *              measurement loop overhead in a correct way, the loop check
+ *              has been made a part of the benchmark. This does have
+ *              an impact - though a very minor one - on the distribution
+ *              statistics which have been updated for this version.
+ *
+ *              All changes within the measurement loop are described
+ *              and discussed in the companion paper "Rationale for
+ *              Dhrystone version 2".
+ *
+ *              Because of the self-imposed limitation that the order and
+ *              distribution of the executed statements should not be
+ *              changed, there are still cases where optimizing compilers
+ *              may not generate code for some statements. To a certain
+ *              degree, this is unavoidable for small synthetic benchmarks.
+ *              Users of the benchmark are advised to check code listings
+ *              whether code is generated for all statements of Dhrystone.
+ *
+ *              Version 2.1 is identical to version 2.0 distributed via
+ *              the UNIX network Usenet in March 1988 except that it corrects
+ *              some minor deficiencies that were found by users of version 2.0.
+ *              The only change within the measurement loop is that a
+ *              non-executed "else" part was added to the "if" statement in
+ *              Func_3, and a non-executed "else" part removed from Proc_3.

+ * Defines:     The following "Defines" are possible:
+ *              -DREG=register          (default: Not defined)
+ *                      As an approximation to what an average C programmer
+ *                      might do, the "register" storage class is applied
+ *                      (if enabled by -DREG=register)
+ *                      - for local variables, if they are used (dynamically)
+ *                        five or more times
+ *                      - for parameters if they are used (dynamically)
+ *                        six or more times
+ *                      Note that an optimal "register" strategy is
+ *                      compiler-dependent, and that "register" declarations
+ *                      do not necessarily lead to faster execution.
+ *              -DNOSTRUCTASSIGN        (default: Not defined)

+ *                      or the "time" function (returning wallclock time)
+ *                      is used for measurement. 
+ *                      For single user machines, "time ()" is adequate. For
+ *                      multi-user machines where you cannot get single-user
+ *                      access, use the "times ()" function. If you have
+ *                      neither, use a stopwatch in the dead of night.
+ *                      "printf"s are provided marking the points "Start Timer"
+ *                      and "Stop Timer". DO NOT use the UNIX "time(1)"
+ *                      command, as this will measure the total time to
+ *                      run this program, which will (erroneously) include
+ *                      the time to allocate storage (malloc) and to perform
+ *                      the initialization.
+ *              -DHZ=nnn
+ *                      In Berkeley UNIX, the function "times" returns process
+ *                      time in 1/HZ seconds, with HZ = 60 for most systems.
+ *                      CHECK YOUR SYSTEM DESCRIPTION BEFORE YOU JUST APPLY

+ *
+ *  Compilation model and measurement (IMPORTANT):
+ *
+ *  This C version of Dhrystone consists of three files:
+ *  - dhry.h (this file, containing global definitions and comments)
+ *  - dhry_1.c (containing the code corresponding to Ada package Pack_1)
+ *  - dhry_2.c (containing the code corresponding to Ada package Pack_2)
+ *
+ *  The following "ground rules" apply for measurements:
+ *  - Separate compilation
+ *  - No procedure merging
+ *  - Otherwise, compiler optimizations are allowed but should be indicated
+ *  - Default results are those without register declarations
+ *  See the companion paper "Rationale for Dhrystone Version 2" for a more
+ *  detailed discussion of these ground rules.
+ *
+ *  For 16-Bit processors (e.g. 80186, 80286), times for all compilation
+ *  models ("small", "medium", "large" etc.) should be given if possible,
+ *  together with a definition of these models for the compiler system used.

+ *
+ *  Dhrystone (C version) statistics:
+ *
+ *  [Comment from the first distribution, updated for version 2.
+ *   Note that because of language differences, the numbers are slightly
+ *   different from the Ada version.]
+ *
+ *  The following program contains statements of a high level programming
+ *  language (here: C) in a distribution considered representative:           
+ *
+ *    assignments                  52 (51.0 %)
+ *    control statements           33 (32.4 %)
+ *    procedure, function calls    17 (16.7 %)
+ *
+ *  103 statements are dynamically executed. The program is balanced with
+ *  respect to the three aspects:                                             
+ *
+ *    - statement type
+ *    - operand type
+ *    - operand locality
+ *         operand global, local, parameter, or constant.                     
+ *
+ *  The combination of these three aspects is balanced only approximately.    
+ *
+ *  1. Statement Type:

+ *  The program does not compute anything meaningful, but it is syntactically
+ *  and semantically correct. All variables have a value assigned to them
+ *  before they are used as a source operand.
+ *
+ *  There has been no explicit effort to account for the effects of a
+ *  cache, or to balance the use of long or short displacements for code or
+ *  data.

+/*  Programme to test how long it takes to select(2), poll(2) and poll2(2) a
+    large number of file descriptors.
+
+    Copyright 1997     Richard Gooch  rgooch@atnf.csiro.au
+    Distributed under the GNU General Public License.
+
+    To compile this programme, use  gcc -O2 -o time-polling time-polling.c
+
+    Extra compile flags:
+
+    Add  -DHAS_SELECT  if your operating system has the select(2) system call
+    Add  -DHAS_POLL    if your operating system has the poll(2) system call
+    Add  -DHAS_POLL2   if your operating system has the poll2(2) system call
+
+    Usage:  time-polling [num_iter] [num_to_test] [num_active] [-v]
+
+    NOTE: on many systems the default limit on file descriptors is less than
+    1024. You should try to increase this limit to 1024 before doing the test.
+    Something like "limit descriptors 1024" or "limit openfiles 1024" should do
+    the trick. On some systems (like IRIX), doing the test on a smaller number
+    gives a *much* smaller time per descriptor, which shows that time taken
+    does not scale linearly with number of descriptors, which is non-optimal.
+    In the tests I've done, I try to use 1024 descriptors.

+ * This is a port of the infamous "gears" demo to straight GLX (i.e. no GLUT)
+ * Port by Brian Paul  23 March 2001
+ *
+ * Exact timing added by Behdad Esfahbod to achieve a fixed speed regardless
+ * of frame rate.  November 2003
+ *
+ * Printer support added by Roland Mainz <roland.mainz@nrubsig.org>. April 2004
+ *
+ * This version modified by Ian Smith, 30 Sept 2007, to make ubgears.
+ * ubgears is cusoimised for use in the UnixBench benchmarking suite.
+ * Some redundant stuff is gone, and the -time option is added.
+ * Mainly it's forked so we don't use the host's version, which could change
+ * from platform to platform.
+ *
+ * Command line options:
+ *    -display         Set X11 display for output.
+ *    -info            Print additional GLX information.
+ *    -time <t>        Run for <t> seconds and produce a performance report.
+ *    -h               Print this help page.
+ *    -v               Verbose output.
