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.
WHAT'S NEW
I discovered even more optimization-switches at the compiler - now
the executables are around 15% faster on my machine.
Release date: 05-Jul-1995
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 some PC's (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
SUN SPARC 20 ? MHZ 135000 GNU/C
PC 486/DX33 33MHz 28000 GNU/C (under LINUX)
PC 486/DX66 66MHz 53000 ? (under OS/2)
PC 486/DX4/100 100MHz 83000 GNU/C (under LINUX)
A4000/40 30MHz 44000 SAS/C
A4000/60/Cyberstorm 60MHZ 90000 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.
