NUMA's about memory access so it's about cores/CPUs/processors/whatever_you_want_to_call_it and how they access memory. [...] >> NUMA is also an option in the kernel.

You could use numactl and place your binary on certain nodes (cores) and check whether that works. You should also check your code uses OpenMP, threading, ... for example. Monitor your CPU and memory also while your software is running ;) What SW are you going to be running? Do you know if your software is SMP and/or NUMA aware? Rafa
