Public bug reported: OpenMPI 1.10.2 has a bug handling cpusets. Here is a link to the mailing list discussion including the patch I'll attach:
https://www.mail-archive.com/users%40open-mpi.org/msg00273.html I encountered this error by adding torque 5.1.1.2 to the system including cpuset support. When I run a job I get this error: -------------------------------------------------------------------------- A request for multiple cpus-per-proc was given, but a directive was also give to map to an object level that has less cpus than requested ones: #cpus-per-proc: 1 number of cpus: 0 map-by: BYSOCKET Please specify a mapping level that has more cpus, or else let us define a default mapping that will allow multiple cpus-per-proc. -------------------------------------------------------------------------- Adding the patch to the deb package and rebuilding it resolved the issue.
