Right, there is some docs which need to be update or even drop, and a reorder would be a timing to push each of arch maintainer to do something, isn't it? Anyway, reordering documents like kernel source dir could be one of choices. :) > > So, in my mind, this needs some thought.

[RFC PATCH] sched/numa: do load balance between remote nodes
commit cb83b629b remove the NODE sched domain and check if the node
distance in SLIT table is farther than REMOTE_DISTANCE, if so, it will
lose the load balance chance at exec/fork/wake_affine points.
But actually, even the node distance is farther than REMOTE_DISTANCE,
Modern CPUs also has QPI like connections, that make memory access is
not too slow between nodes. So above losing on NUMA machine make a
huge performance regression on benchmark: hackbench, tbench, netperf
and oltp etc.
This patch will recover the scheduler behavior to old mode on all my
Intel platforms: NHM EP/EX, WSM EP, SNB EP/EP4S, and so remove the
perfromance regressions. (all of them just has 2 kinds distance, 10 21)

I just felt a little uneasy re-purposing the RECLAIM_DISTANCE for this, but I guess its all the same anyway. Both mean expensive-away-distance. I understand you, the BIOS guys don't have a good alignment with us on this. So I've taken this. thanks! ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
