I tried Crafty on the RS/6000 43P-140 last summer. I used the AIX compiler and can't remember any significant problems. The executable can be tuned for the architecture. The 43P I have uses a PowerPC 604 at 200 MHz. I got best results with options -O2 -qtune=604. The performance of the PPC 604 at 200 MHz is comparable with an Intel Pentium II at 255 MHz. The current top workstation of the RS/6000 is the 43P-150 using the PPC 604e at 375 MHz and a faster memory subsystem with SDRAM. I estimate you can get to 215000 nps on this hardware. I hope to get my hands on a fully equiped model F50 this month, using 4 x PPC 604e at 332 MHz. I will report benchmarks for Crafty when I get the chance to. I guess it will be possible to reach 750000 nps. ALbrecht Heeffer
