No Comment
The 64-bit versions of Windows 7 and Windows Server 2008 R2 support more than 64 Logical Processors (LP) on a single computer. New processors are now appearing that leverage non-uniform memory access (NUMA) architectures. Within the near future, a system with 4 CPU sockets, 8 processor-cores per socket and with Simultaneious Multi-Threading (SMT) enabled per core, will achieve 64 Logical Processors. Many server-class solutions will need to be architected with NUMA awareness in order to achieve linear performance scaling on 64+ LP systems.
