[Cialug] NUMA v. non-NUMA on a processor basis

[Nathan C. Smith]

Sort of a virtualization question I guess.

Is using NUMA still preferred when doing virtualization on a single processor machine with multiple cores, or is NUMA purely for multiple physical processor clusters?

What about NUMA when virtualization is not in use?  Any benefit or performance penalty on a single or multiple processor machine?

Thanks.
