General Notes
Software environment:
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
setenv MPI_TYPE_MAX 32768
Determines the maximum number of data types 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: 1024
setenv MPI_BUFS_THRESHOLD 1
Determines whether MPT uses per-host or per-process message
buffers for communicating with other hosts. Per-host buffers
are generally faster but for jobs running across many hosts they
can consume a prodigious amount of memory. MPT will use per-
host buffers for jobs using up to and including this many hosts
and will use per-process buffers for larger host counts.
Default: 64
setenv MPI_DSM_DISTRIBUTE
Activates NUMA job placement mode. This mode ensures that each
MPI process gets a unique CPU and physical memory on the node
with which that CPU is associated. Currently, the CPUs are
chosen by simply starting at relative CPU 0 and incrementing
until all MPI processes have been forked.
limit stacksize unlimited
Removes limits on the maximum size of the automatically-
extended stack region of the current process and each
process it creates.
PBS Pro batch scheduler (www.altair.com) is used with
placement sets to ensure each MPI job is assigned to
a topologically compact set of nodes
