This is why I CC'd the maintainer of the will-it-scale github project, Anton Blanchard. My main intent is to report this issue to him, but I have not heard back from him yet. Is this project maintained ? Let me try to add his ozlabs.org address in CC. > For this test case, if we bind the workload to a specific CPU, then it > will hide the scheduler balance issue.

When you say that you bind the workload to a specific CPU, is that done outside of the will-it-scale testsuite, thus limiting the entire testsuite to a single CPU, or you expect that internally the will-it-scale context-switch1 test gets affined to a single specific CPU/core/hardware thread through use of hwloc ?
