What would you reccomend in the ay of fairly inexpensive processors? I was looking at the AMD line, mabe a k6-350, what do you think. Are these the same socket and voltage set up? The only cpu that is supported on SMP is the Intel's. The other thing to remember is payback decreases around 3x on the bus speed. Your 200 is 3x. If you want throughput, you need 100Mhz memory and that means a P-ii 350 or faster. The old rule for throughput is 1.8x times the speed of the single cpu. Two PP200 would effectively be a PP360. The P-II 350 w/PC100 memory can still be 1.5 times faster because the memory is 1.5 times faster. I have setiathome running on two WinNT machines and they crank out a work unit in 9-10 hours. The FreeBSD system with a Celeron 433 cranks out a work unit in 14-15 hours (~1.5). Kent > > Also, what would I need to do after the CPU upgrade? Recompile the kernel, or?
