You have found what we found (also in other areas of OpenMPI) that Slurm has some interesting behaviors.

Slurm node config is as follows: NodeName=n[001-008] RealMemory=258452 Sockets=4 CoresPerSocket=16 ThreadsPerCore=1 State=UNKNOWN Port=[17001-17008] But we get this error--so I suspect it's a parsing error on the slurm side? No, it's slurm properly reading info from hwloc, but that info doesn't match the actual hardware because the BIOS is buggy. Brice
