Bug Description

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.
