orte-clean(1) Open MPI orte-clean(1)
NAME
orte-clean - Cleans up any stale processes and files leftover from Open MPI jobs.
SYNOPSIS
orte-clean [--verbose] mpirun --pernode [--host | --hostfile file] orte-clean [--verbose]
OPTIONS
[-v | --verbose] This argument will run the command in verbose mode and print out the universes that are getting cleaned up as well as pro- cesses that are being killed.
DESCRIPTION
orte-clean attempts to clean up any processes and files left over from Open MPI jobs that were run in the past as well as any currently run- ning jobs. This includes OMPI infrastructure and helper commands, any processes that were spawned as part of the job, and any temporary files. orte-clean will only act upon processes and files that belong to the user running the orte-clean command. If run as root, it will kill off processes belonging to any users. When run from the command line, orte-clean will attempt to clean up the local node it is run from. When launched via mpirun, it will clean up the nodes selected by mpirun.
EXAMPLES
Example 1: Clean up local node only. example% orte-clean Example 2: To clean up on a specific set of nodes specified on command line, it is recommended to use the pernode option. This will run one orte-clean for each node. example% mpirun --pernode --host node1,node2,node3 orte-clean To clean up on a specific set of nodes from a file. example% mpirun --pernode --hostfile nodes_file orte-clean Example 3: Within a resource managed environment like N1GE, SLURM, or Torque. The following example is from N1GE. First, we see that we have two nodes with two CPUs each. example% qsh -pe orte 4 example% mpirun -np 4 hostname node1 node1 node2 node2 Clean up all the nodes in the cluster. example% mpirun --pernode orte-clean Clean up a subset of the nodes in the cluster. example% mpirun --pernode --host node1 orte-clean
