...will be a computer with up to four sockets, each filled with a quad core CPU that, in the case of Intel CPUs, will be hyper-threaded. This means the standard system in the data center will have up to 64 virtual processors.
Is there a 4-way hyperthreading variant I haven't heard about? I thought HT was always viewed as two CPUs by the Linux kernel (well, assuming it's enabled in the BIOS and the kernel config), which would imply no more than 32 virtual processors. Did I miss something here?
