Subject: [PATCH 0/6] sched,numa: weigh nearby nodes for task placement on complex NUMA topologies (v2)
Date: Fri, 17 Oct 2014 03:29:48 -0400 [thread overview]
Message-ID: <1413530994-9732-1-git-send-email-riel@redhat.com> (raw)
This patch set integrates two algorithms I have previously tested,
one for glueless mesh NUMA topologies, where NUMA nodes communicate
with far-away nodes through intermediary nodes, and backplane
topologies, where communication with far-away NUMA nodes happens
through backplane controllers (which cannot run tasks).
Due to the inavailability of 8 node systems, and the fact that I
am flying out to Linuxcon Europe / Plumbers / KVM Forum on Friday,
I have not tested these patches yet. However, with a conference (and
many familiar faces) coming up, it seemed like a good idea to get
the code out there, anyway.
Vinod tested the v1 series + patch 6 on a backplane topology
system, and I changed v2 on a glueless mesh topology system.
The patches appear to behave.
Placement of tasks on smaller, directly connected, NUMA systems
should not be affected at all by this patch serie
v2: remove the hops table, and use numa_distance instead, tested
on a system with glueless mesh topology, not yet tested on
a backplane style system (but the algorithm should be unchanged)
