General Notes
setenv MPI_DSM_DISTRIBUTE 1
Ensures that each MPI process gets a unique CPU and physical
memory on the node with which that CPU is associated. 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.
