Here is Reinhold Weicker's DHRYSTONE 2.1 benchmark, slightly modified
|
| 4 |
|
|
by me for instrumentation purposes only. This is an integer CPU
|
| 5 |
|
|
benchmark. The differences between 2.0 and 2.1 are minor, and
|
| 6 |
|
|
I believe that 2.0 and 2.1 results are comparable.
|
| 7 |
|
|
|
| 8 |
|
|
For purists, I've enclosed context diffs to turn what I'm posting
|
| 9 |
|
|
as 2.1 back into what Reinhold sent me as 2.1. The changes
|
| 10 |
|
|
are in pure2_1.dif. As you can see, it is only the instrumentation
|
| 11 |
|
|
that is slightly different.
|
| 12 |
|
|
|
| 13 |
|
|
Both the C and the Pascal versions are here. The Ada version I
|
| 14 |
|
|
have is marked preliminary (not to be posted).
|
| 15 |
|
|
|
| 16 |
|
|
I've enclosed a new submission form (note new address for mailings).
|
| 17 |
|
|
Please deluge this mailbox (..!uunet!pcrat!dry2) with your results.
|
| 18 |
|
|
I'll summarize and repost when the dust clears. Please do not
|
| 19 |
|
|
assume that I will pull posted results off of the net (I won't, its
|
| 20 |
|
|
too much work).
|
| 21 |
|
|
|
| 22 |
|
|
I've attempted to include a Makefile for UNIX and Microsoft C (with ndmake).
|
| 23 |
|
|
Pay particular attention to the HZ parameter, even though your power may
|
| 24 |
|
|
be 50 or 60 hertz, your computer may not be. You may have to ask someone,
|
| 25 |
|
|
read the manual, or check:
|
| 26 |
|
|
/usr/include/sys/param.h
|
| 27 |
|
|
/usr/include/limits.h (CLK_TCK==HZ)
|
| 28 |
|
|
for this information.
|
| 29 |
|
|
|
| 30 |
|
|
REPEAT: HZ IS NOT NECESSARILY THE FREQUENCY OF YOUR AC POWER !!!!!!
|
| 31 |
|
|
|
| 32 |
|
|
There are two versions to run, one with register variables, and one
|
| 33 |
|
|
without. Please let the benchmark run for 30,000 loops on sixteen
|
| 34 |
|
|
bit machines, and for much longer (a minute or two) on faster machines.
|
| 35 |
|
|
Please note that "time(2)" has a resolution of 1 second, and may give
|
| 36 |
|
|
variable results. No matter how time is measured, a sanity check with
|
| 37 |
|
|
a stopwatch is prudent. We've run into systems that lie about time,
|
| 38 |
|
|
and there is always the configuration error problem. When it comes
|
| 39 |
|
|
to time measurement on UNIX, there is no widely adhered to standard.
|
| 40 |
|
|
|
| 41 |
|
|
For segmented architectures, it is appropriate to submit results for
|
| 42 |
|
|
all memory models, as shown below.
|
| 43 |
|
|
|
| 44 |
|
|
I dropped the CODESIZE information that I attempted to add the last
|
| 45 |
|
|
time I posted this. People couldn't follow directions, and the
|
| 46 |
|
|
information wasn't very useful anyway.
|
| 47 |
|
|
|
| 48 |
|

Here's a sample submission of results:

The program that processes submission forms is rather dumb. Please
|
| 85 |
|
|
do not change the order, add or removes lines in the form. If your
|
| 86 |
|
|
NOTES are longer than the space provided, then they are too long for
|
| 87 |
|
|
the summary. Keep it terse, please.
|
| 88 |
|
|
|
| 89 |
|
|
A form consists of all lines between:
|
| 90 |
|
|
DHRYSTONE 2.1 BENCHMARK REPORTING FORM
|
| 91 |
|
|
and
|
| 92 |
|
|
MAILTO: uunet!pcrat!dry2
|
| 93 |
|
|
both lines must be present for the form to be processed. If
|
| 94 |
|
|
a field does not apply or is not known, leave it blank. The fields
|
| 95 |
|
|
are:
|
| 96 |
