SubjectHow can I optimize a process on a NUMA architecture(x86-64 specifically)?
Say you have a bunch of single-threaded processes on a NUMA machine. 
Does the kernel make sure to prefer allocations using a certain CPU's
memory, preferring to run a given process on the CPU which contains its
memory? Or should I use the NUMA API(libnuma) to spell this out to the
kernel? Does the kernel do the right thing in this case?


Thanks,

Brett
