The bad thing from 2003 was that for 1.5 years i had no time to improve diep's eval, apart from 0 testing been done. I would be very amazed if diep is the only engine using a quad dual core at world champs 2005. Actually that hardware is far cheaper than the other quad machines that might be around there. Shredder will be able to easily get a quad opteron dual core, so will Junior. For shredder i realize that a 2.6ghz opteron with a tuned bios is far more interesting than running at 8 cpu's 2.2Ghz dual core anyway, thanks to speedup reasons, and memory latency where shredder relies upon a lot. Junior i have no real idea. They are not giving out much info, i'll see it at their nodecount when they're there. Besides, Bob still has 8 days to modify crafty to get it to work at dual core. Any of all these guys can lay their hands on faster dual core chips than hotels.nl great machine, yet if they can't use it, that means more than ever that the incentive to run on faster hardware is getting less interesting to them. In a few years time with 16 core processors, who knows, perhaps everyone is happy enough to just take a laptop with a 8 core processor as that's plenty fast. Vincent
