Short: UN*X port (SAS adapted), incl. binaries Author: Torsten Hiddessen / math@sun.rz.tu-clausthal.de Uploader: Torsten Hiddessen / math sun rz tu-clausthal de Type: util/moni Architecture: m68k-amigaos 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. 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 ?
