COPYRIGHT
This package is public-domain. This means you can copy it freely
as long as you don't ask any money for it, except perhaps a nominal
fee for copying.
CONTENTS
This package contains the well known 'Dhrystone' benchmark. It's
available everwhere on the net - but if you wish to compile it on
AMIGA, you need to alter the source a little bit. The source is
adapted to take advantage of the 'timer.device' - NOTHING else has
been altered.
USAGE
Just run your favourite version (1.0, 1.1 or 2.1) from your
'processors directory' (68000+, 68020+, 68040+). For each CPU, the
benchmark runs at a useful (IMHO) loop count. The excutables are
compiled under SAS/C 6.55.
INFO
I wished to have the standard dhrystone around - just from the
original sources and optimized for my processor. So I could compare
our workstations and a 486/DX33 (under LINUX) to my A4000/040. Here
are the results from Dhrystone 1.1:
Machine: Clock: Result: Compiler:
---------------------------------------------------------------------
DEC ALPHA AXP (150MHz): 427000 CC (GNU/C rates 377000, only)
SUN SPARC 10 ( 33MHz): 83000 GNU/C
PC 486/DX33 ( 33MHz): 28000 GNU/C
A4000/40 ( 30MHz): 38000 SAS/C
Notice, that I NEVER compiled the benchmark 'register-optimized',
because this benchmark should rate the speed of the
processor-memory interface (while performing lots of 'string-copy')
and not the capability of the CPU (especially at RISC-design) to
store runtime variables at dozens of registers.
GREETINGS
to Steffi, Jerome, Mark, Stefan, Michael, Thomas, as usual..

comments (or just mail your results - especially from 68060) then
