AMD improves hardware virtualization support
Story on the wires this week about AMD’s partnership with VMware to improve support for migration of virtual machines between different versions of AMD processors.
AMD-V Extended Migration provides the necessary support for virtualization software to mask the differences between CPU generations, facilitating the safe live migration of virtual machines between servers running different generations of AMD processors. This includes existing single-core and dual-core processors and all future AMD processor revisions, including the upcoming “Barcelona” Quad-Core AMD Opteron processors, the first native x86 quad-core microprocessor.
If you’re headed to SF in mid-September, AMD will be showcasing AMD-V Extended Migration using VMware at VMworld.
AMD announces ISA extensions for HPC
AMD announced this week they’re adding new instruction set extensions designed to improve performance in HPC, multimedia, and security apps.
