MPI_SPINDTIMEOUT

When coscheduling is enabled, limits the length of time (in milliseconds) a message will remain in the poll waiting for the spind daemon to return. If the timeout occurs before the daemon finds any messages, the process re-enters the polling loop. The default value is 1000 ms. A default can also be set by a system administrator in the hpc.conf file.
