On a 48 core AMD bulldozer node with Ubuntu kernel 3.13.0-57-generic i get this with hwloc 1.11.0 * hwloc 1.11.0 has encountered what looks like an error from the operating system. * L3 (cpuset 0x000003f0) intersects with NUMANode (P#0 cpuset 0x0000003f) without inclusion! An identical node with kernel 3.2.0-87-generic and hwloc 1.11.0 shows no problem. (The hwloc version in openmpi 1.8.6 also shows the same type of problem but with a slightly shorter message)
