The CPUs are chosen by simply starting at cpuset-relative CPU 0 and incrementing until all MPI processes have been forked. setenv MPI_REQUEST_MAX 65536 Determines the maximum number of nonblocking sends and receives that can simultaneously exist for any single MPI process. MPI generates an error message if this limit (or the default, if not set) is exceeded. Default: 16384 limit stacksize unlimited Removes limits on the maximum size of the automatically- extended stack region of the current process and each process it creates.
