嗯,終於有人在做Virtual SMP這玩意了...

ScaleMP
ScaleMP Makes Big SMPs Out of Little Ones

產品有這兩種:

vSMP Foundation Embedded - enables high-end x86 systems, leveraging standard, off-the-shelf components. vSMP Foundation Embedded supports 4 to 32 processors (128 cores) and up to 1 TB of shared memory. Systems based on vSMP Foundation Embedded are the largest x86 systems in the industry, providing an SMP user experience at cluster prices.

vSMP Foundation Standalone - provides four-socket x86 platform with up to 128 GB RAM. vSMP Foundation Standalone offers tremendous price and performance advantages over traditional four-sockets solutions, with 25% power consumption savings, 50% rack-space savings and more than 70% price/performance advantage.

沒用過,不知道效率如何。反倒是這讓我想起之前UNSW發展的vNUMA...

Itanium Virtualization and vNUMA
vNUMA: Virtual Multiprocessors on Clusters of Workstations

題外話,原來IA-64的sensitive指令多達七個,難怪需要加上VT-i,當初設計指令集的人能不能被拖去槍斃呀?
