set_mmtests_numactl wasn't invoked #21

Closed ZhangYet closed 1 year ago

ZhangYet commented 2 years ago

Found that set_mmtests_numactl wasn't invoked before so that export MMTESTS_NUMA_POLICY="fullbind_single_instance_cpu" didn't work when testing the impact of NUMA policies on redis. So I made some changes.

https://github.com/gormanm/mmtests/pull/20

But I found MMTESTS_NUMACTL in some bench like /shellpack_src/src/iozone/iozone-bench, and I don't know why.

NUMA policies and how they are applied needs a rethink. It's somewhat benchmark specific how the binding should be done so it needs to be divided into generic and benchmark-specific configuration options. As bindings are not often used, it's on the backburner to address in a sensible fashion.
