ANNOUNCMENT
Attached, please find the 11/08/85 list of DHRYSTONE benchmark results.
The source code for the drystone benchmark can be found in net.sources.
The latest list includes many new machines/compiler combinations. Many
of the questionable results have been confirmed or corrected. I am still
waiting for Intel 386 results; I'm sure many others are, too.
CLARIFICATION
There seems to have been a great deal of confusion over what this
benchmark measures, and how to use these results. Let me try to clarify
this:
1) DHRYSTONE is a measure of processor+compiler efficiency in
executing a 'typical' program. The 'typical' program was
designed by measuring statistics on a great number of
'real' programs. The 'typical' program was then written
by Reinhold P. Weicker using these statistics. The
program is balanced according to statement type, as well
as data type.
2) DHRYSTONE does not use floating point. Typical programs don't.
3) DHRYSTONE does not do I/O. Typical programs do, but then
we'd have a whole can of worms opened up.
4) DHRYSTONE does not contain much code that can be optimized
by vector processors. That's why a CRAY doesn't look real
fast, they weren't built to do this sort of computing.
5) DHRYSTONE does not measure OS performance, as it avoids
calling the O.S. The O.S. is indicated in the results only
to help in identifying the compiler technology.
If somebody asked me to pick out the best machine for the money, I
wouldn't look at just the results of DHRYSTONE. I'd probably:
1) Run DHRYSTONE to get a feel for the compiler+processor
speed.
2) Run any number of benchmarks to check disk I/O bandwidth,
using both sequential and random read/writes.
3) Run a multitasking benchmark to check multi-user response
time. Typically, these benchmarks run several types of
programs such as editors, shell scripts, sorts, compiles,
and plot the results against the number of simulated users.
4) If appropriate for the intended use, run WHETSTONE, to determine
floating point performance.
5) If appropriate for intended use, run some programs which do
vector and matrix computations.
6) Figure out what the box will:
- cost to buy
- cost to operate and maintain
- be worth when it is sold
- be worth if the manufacturer goes out of business
7) Having done the above, I probably have a hand-full of
machines which meet my price/performance requirements.
Now, I find out if the applications programs I'd like
to use will run on any of these machines. I also find
out how much interest people have in writing new software
for the machine, and look carefully at the migration path
I will have to take when I reach the limits of the machine.
To summarize, DHRYSTONES by themselves are not anything more than
a way to win free beers when arguing 'Box-A versus Box-B' religion.
They do provide insight into Box-A/Compiler-A versus Box-A/Compiler-B
comparisons.
As usual, all comments and new results should be mailed directly
to me at ..{ihnp4,..others..}!houxm!castor!rer. I will summarize
and post to the net.
