Donald Becker: > In the Scyld Beowulf system (well, specifically the professional > editions) we ship six different kernel variously optimized for > Pentium-4, Athlon, and uniprocessor/SMP. And with the current system Can you elaborate on the actual performance differences/gains that these kernels show? The things that I would optimize are memcpy() and maybe libm - but do you really need different kernels for this? Function ptrs should do the job. What else benefits from optimizations?
