Hi,
This is the latest iteration of our numa/core tree, which
implements adaptive NUMA affinity balancing.
Changes in this version:
https://lkml.org/lkml/2012/11/12/315
Performance figures:
https://lkml.org/lkml/2012/11/12/330
Any review feedback, comments and test results are welcome!
For testing purposes I'd suggest using the latest tip:master
integration tree, which has the latest numa/core tree merged:
git pull git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git master
(But you can also directly use the tip:numa/core tree as well.)
Thanks,
Ingo
