mpirun_elan is a tool that enables programs linked with the Quadrics QsNet MPI library to run on a ParaStation MPI cluster under control of the ParaStation MPI process management facility. Within ParaStation MPI the startup of parallel jobs is handled as described within the process_placement(7) manual page. The spawning mechanism is steered by environment variables, which are described in detail within ps_environment(7).
mpirun_elan typically works like this:
mpirun_elan -npnumprog[args]
This will startup the program prog
num times in parallel forming a
parallel job.
Args are optional argument which will be
passed to each instance of prog.
-np num
Number of processes to create.
-n,
--nodes=nodeslist
List of node numbers to use.
-h,
--hosts=hosts
List of hosts to use.
--hostfile=hostfile
Hostfile to use.
-sort=criteria
Sorting criteria to use: proc,
load,
proc+load or
none.
-sourceprintf
Print output-source info.
-rusage
Print resource usage when finished.
-e,
-exports=envlist
Environment to export to foreign nodes.
-k, --keep
don't remove mpihosts file upon exit.
-v, --verbose
Print diagnostic messages.
-V, --version
Output version information and exit.
-?, --help
Show this help messages.
--usage
Display brief usage message.
