From 0d92363564de7b755f47ab91aaafa0ec197a36af Mon Sep 17 00:00:00 2001 From: James Simmons Date: Wed, 2 Mar 2016 17:01:54 -0500 Subject: [PATCH] staging: lustre: bind socklnd peers to a specific CPT Currently the socklnd driver doesn't support CPT affinity for its peers. Binding peers to a specific CPT and memory allocated to the NUMA node belonging to the CPT should give a performance boost.
