MPI_COSCHED

Specifies the user's preference regarding use of the spind daemon for coscheduling. Values can be 0 (prefer no use) or 1 (prefer use). This preference may be overridden by the system administrator's policy. This policy is set in the hpc.conf file and can be 0 (forbid use), 1 (require use), or 2 (no policy). If no policy is set and no user preference is specified, coscheduling is not used.

If no user preference is specified, the value 2 will be shown when environment variables are printed with MPI_PRINTENV.
