I put "virtual" there on purpose. Here's what I can publically share: http://www.tgdaily.com/content/view/43776/135/ and there's more to come. On a public front it is still 512 not 1K, though: 4 cpus per box * 16 physical cores per cpu * 8 virtual threads per core > and is apple doing such a thing? Nobody knows what Apple is doing for sure. I know 3 things though: 1. Apple badly wants a share of a server market 2. Apple is still doing POWER, though not releasing it (just like they did x86 for 7 or so years without telling anyone) 3. POWER is getting to 1K SMP as well. > even commodity intel and amd mp offerings are numa. > they're not very n, but they're still n. True. But even for those platforms good SMP frameworks are quite difficult to come by. And here I do mean computation, not how to accommodate scalable IO. Thanks, Roman.
