That is what is expected, yes (though only at the PU level, since only that one is completely included in the cpuset, you would need "intersects" to get the path). and that's what I get on my machine: € ./test This system has 7 levels Cpuset: 0x00000040 Number of objects at depth 0: 0 Number of objects at depth 1: 0 Number of objects at depth 2: 0 Number of objects at depth 3: 0 Number of objects at depth 4: 0 Number of objects at depth 5: 0 Number of objects at depth 6: 1 > Evidently my understanding of this functionality is still > not correct. No, it's completely correct, it just seems there's an odd thing somewhere. Could you run through strace so we can check what the kernel returns? Samuel
