Or could mbind be > used to set up a policy and then the cpuset would change? My intention (hopefully the code matches this) is that mbind nodes are constrained to fit in the cpuset. If you ask to mbind more nodes, those outside the cpuset are masked off. If you later change the cpuset, then we mask more nodes off to continue to fit in the cpuset. If this gets us down to an empty mbind list, then you get to use whatever memory nodes are in your new cpuset. -- I won't rest till it's the best ...
