High Performance Computing Virtualization | Virtual SMP | ScaleMP

High Performance Computing Virtualization | Virtual SMP | ScaleMP: "The innovative Versatile SMP™ (vSMP) architecture aggregates multiple x86 systems into a single virtual x86 system, delivering an industry-standard, high-end symmetric multiprocessor (SMP) computer. Using software to replace custom hardware and components, ScaleMP offers a new, revolutionary computing paradigm."

Another way to scale-out server virtually: Build a big "logical" x86 server out of multiple relatively inexpensive x86 servers, instead of getting big Sun (ahem ... Oracle) or IBM SMP servers. Servers are connected via Infiniband. Unlike Vmware/Xen hypervisors, this method allows a workload to transparently span the resources of multiple physical servers. But even with Infiniband, the memory latency can still be very significant. I remember experiencing very poor scale-out performance on DB2 with the IBM x3950 multi-chassis setup.

Some good articles that describes virtual SMP solutions:

I would love to see some real world benchmarks of these virtual SMP solutions vs hardware optimized SMP servers.
