They're sold as 32-ways today on the x445 (that's physical, without hyperthreading). I've personally booted Linux on a 16-way, but I'm know others have booted on the 32-way configuration. Patches for this were posted in the last week by James Cleverdon. There's also the bigsmp code in the kernel for other P4-based systems that are >8x. I haven't seen any of them yet, but I wouldn't imagine that people would put support in the kernel for hardware that wasn't at least *close* to production. -- Dave Hansen haveblue@us.ibm.com
