Subject: How can I optimize a process on a NUMA architecture(x86-64 specifically)?
Date: Thu, 20 May 2004 17:51:48 -0700	[thread overview]
Message-ID: <40AD52A4.3060607@fastclick.com> (raw)

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
