Subject: [PATCH 0/3] sched,numa: further numa balancing fixes
Date: Sat, 14 Jun 2014 15:18:56 -0400 [thread overview]
Message-ID: <1402773539-6466-1-git-send-email-riel@redhat.com> (raw)
A few more bug fixes that seem to improve convergence of
"perf bench numa mem -m -0 -P 1000 -p X -t Y" for various
values of X and Y, on both 4 and 8 node systems.
This does not address the issue I highlighted Friday:
https://lkml.org/lkml/2014/6/13/529
I have an idea on how to fix that issue, but implementing
that as part of this series would be silly, since I would
have to rip the code back out and completely rewrite it
once I started working on placement for systems with complex
NUMA topologies. Better to leave that code for then...
Patches are against the latest -next and -tip trees.
