NAME
wwmpirunDESCRIPTION
wwmpirun Is a wrapper for the systems mpirun command. It first locates the number of idle CPU's requested and then wraps the mpirun command so that the user doesn't have to locate free nodes to run jobs by hand.OPTIONS
- --np
- Define the number of processes that you wish to launch. This is a required option.
- -m --master
- How many (if any) jobs do you wish to launch on the master. This is assumed to be none unless you are running a lam enviornment which requires the current node to be included (usually the master).
- -l --lam
- Use the LAM-MPI runtime enviornment (eg. lamboot/lamhalt).
- -h --help
- Show the help screen.
ENVIORNMENT
- MPIRUN
- The actual mpirun command that is intended to be wrapped. If undefined, this will default to 'mpirun' and will use the first one in the default path.
- NODES
- The NODES enviornment variable will limit which nodes are displayed. It can be used either as a list of nodes, seperated by commas, or pointed to a file which contains a list of node names. You can set it with the following syntax:
for bash:
-
- export NODES=node0000,node0001,node0010,node0011
for (t)csh:-
- setenv NODES /path/to/node/list/file
