See linux-mm. We just went through a series of tests and functionality wise it worked just fine. > translate a single node machine into N different nodes.

Yes this is a new way of using cpusets but it works and we could fix the scalability issues rather than adding new subsystems. > And what happens when you want to have cpuset with memory that needs to > be even further fine grained than each node.

I think we should have one container mechanism instead of multiple. Maybe merge the two? The cpuset functionality is well established and working right. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
