I think that XP comes licensed for up to two processors; Server 2000/2003 are licensed for up to quad processors. I don't know how they'll count multicore machines, but I recon they won't care whether it's in two chips or one; dual-processors will be counted as two either way. Thomas P.

Microsoft recently came out and said they would allow single-processor licenses to operate across multiple processor cores. Seems like someone could get a lot of use from a P4 Extreme Edition with HT (4 quasi-parallel units) by creating a cheap workgroup/Web server out of it. I know Intel and AMD are/will be releasing server versions of their multicore CPUs, but have consistently found reliable servers using desktop processors to be far less expensive. Since my program's needs aren't huge but would definitely take advantage of parallel processing, cheap is good - has anyone else investigated this angle? Companies probably won't be selling this type of machine for a few months, but it just sounds like a big win for the small fry server market. -Orion |Orion A Smith, REACH Technology Coordinator| |457 Erickson Hall, MSU (517)432-4022| [log in to unmask]
