node utilization

[Phex]

Hi there.

I am running a Linux Mint guest on a Windows 7 Host with two processors, each providing 8 physical cores. As there is no resource-demanding process running on the host, I have dedicated all 16 physical cores to the VM, or at least I supposed so. When I now run 16 different, non-multi-threading and resource demanding jobs inside the VM, I only see one node utilized on my host (NUMA node 1), ie 8 cores. Does it mean that only one processor is actually being used? I assume that NUMA node 0 and NUMA node 1 belong to either one of the two processors (not knowing how to check this). If that is the case, then I would only make use of 16 logical cores ie 8 physical cores ie half of the possible performance, right? If all I am writing makes sense, then how can I change the configuration to really make sure that all 16 physical cores are being used?

Host: Windows 7 SP1
Guest: Linux Mint 15
DELL T7600 with 2x Intel 2687w (8 cores)

Thank you for your comments.
