Very few commercial engines run on Linux. beta versions 64 bits is ok too. well what do i need to say about the engines that work under linux. to egoistically start with myself and the nearby neighbours: diep, sjeng, shredder, sos, yace if i understand chessbase has a sponsor that just delivers P4 machines, though they did deliver a dual K7 in the past a few times too. At world champs chessbase usually exchanges their sponsor in order to get better hardware. but fritz cannot convert within 1 year to x86-64 as enitre program must get rewritten. So most likely you will see some p4 sponsor boxes because the sponsor provided it and buying yourself hardware is too expensive for chessbase which only makes a couple of millions netto profit a year (my guess, considering the huge personnel they have). So shredder will be a victim here possibly. Then there is engines like warp which instead of an opteron need a decent compiler first (THAT WILL SPEED IT UP WAY MORE THAN HARDWARE) and who won't be carrying a machine with him anyway even though he got divided 5th last time with me and with a better executable/hardware would have done way better. So then we have gandalf which if it shows up i guess will show up at AMD hardware and so on. I still forgot to mention products like pharaon which probably will work under linux too if needed. Junior is a special case. it will be VERY fast at the dual opterons. However they get sponsored by intel-germany if i understand well. So most likely they will show up at some big smoking iron (litterary smoking as they tend to overclock 'a bit' as it is their 'own' machine and they want to win). But i'm sure that many still show up with AMD64s/opterons. I for sure would show up with 500 of them, except that i got no choice and must be happy with 500Mhz MIPS R14000 with 8MB L2 cache and 2300 ns latency to get a 64 bits variable from the other side of the machine. Note this is a measured timing. All the crap times published here are nonsense. The dual K7 is like nearly 400ns to deliver something. Idem dual Xeon. I guess the biggest IBM machines will be doing about 20000 nanoseconds, so that makes the 2300 ns from SGI pretty good still. Despite that SGI propaganda department says it is 460 ns :) Now compare that with opteron local and global latency times to RAM. And you know why people will love it.
