However, with Linux and BIOS NUMA support as well, one must choose between
128-bit inter-node interleaving and NUMA. If you enable inter-node
interleaving, you by definition disable NUMA since the memory addresses
are interleaved across both CPUs. Disabling 128-bit quad-channel access,
setting same-node interleaving, dual-channel 64-bit access only, still
allows the dual-channel access per node, while ALSO allowing NUMA
addressing, with each CPU (single or now dual-core) getting "local" access
to its memory to run its threads, in preference to cross-HYPERLINK access
to the memory associated with the other CPU and memory controller.
Thanks, Duncan that is very interesting.
This was where I was heading with the question, although it was off-topic :S
I will definately look into this more when the system arrives :)
Cheers,
