Neil, we are talking about 384 cores seen by the sum of all OSes (64 per node OS).
No special trick to overprovisione the nodes.

In the new intel machines "Nehalem" class, we have a technology called "hyperthreading" (remember pentium 4 ? same thing).
There's 192 physical cores, but seen as 384 cores by the OS.

That's the way it is supposed to be deployed in production, VT included.
But i can always try to disable the feature in the BIOS if needed.

thanks
