Subject: [PATCH v3 0/2] sched: smart wake-affine
Date: Thu, 04 Jul 2013 12:55:00 +0800 [thread overview]
Message-ID: <51D50024.10902@linux.vnet.ibm.com> (raw)
Since v2:
Add patch [PATCH 2/2] sched: reduce the overhead of obtain factor
for optimization. (Thanks to PeterZ)
This patch-set will implement a smart wake-affine, in order to regain the
lost performance of the workload like pgbench, meanwhile reserve the gained
benefit of the workload like hackbench.
