Aubrey,

Thanks for testing with your set up.

I think the test that's of interest is to see my load balancing added on top
of Aaron's fairness patch, instead of using my previous version of
forced idle approach in coresched-v3-v5.1.5-test-tim branch.

I've added my two load balance patches on top of Aaron's patches
in coresched-v3-v5.1.5-test-core_vruntime branch and put it in

https://github.com/pdxChen/gang/tree/coresched-v3-v5.1.5-test-core_vruntime-lb

I hope to improve the forced idle time later. But for now let's see if
additional load balance logic can help remove cgroup mismatch
and improve performance, on top of Aaron's fairness patches.

Thanks.

Tim
