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 running 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 SEE ALSO

OMPI-RESTART(1) Open MPI OMPI-RESTART(1) NAME
ompi-restart, orte-restart - Restart a previously checkpointed parallel job using the Open PAL Checkpoint/Restart Service (CRS) NOTE: ompi-restart, and orte-restart are all exact synonyms for each other. Using any of the names will result in exactly identical behav- ior. SYNOPSIS
ompi-restart [ options ] <GLOBAL SNAPSHOT HANDLE> Options ompi-restart will attempt to restart a previously checkpointed parallel job from the global snapshot handle reference returned by ompi_checkpoint. <GLOBAL SNAPSHOT HANDLE> The global snapshot handle reference returned by ompi_checkpoint, used to restart the job. This is required to be the last argu- ment to this command. -h | --help Display help for this command -p | --preload Preload the checkpoint files on the remote systems before restarting the application. Disabled by default. --fork Fork off a new process, which is the restarted process. By default, the restarted process will replace ompi-restart. -s | --seq The sequence number of the checkpoint to restart from. By default, the most recent sequence number is used (specified by -1). -hostfile | --hostfile The hostfile from which to restart the application. Useful in unscheduled environments. (Same behavior as --machinefile option) -machinefile | --machinefile The machinefile from which to restart the application. Useful in unscheduled environments. (Same behavior as --hostfile option) -v | --verbose Enable verbose output for debugging. -gmca | --gmca <key> <value> Pass global MCA parameters that are applicable to all contexts. <key> is the parameter name; <value> is the parameter value. -mca | --mca <key> <value> Send arguments to various MCA modules. DESCRIPTION
ompi-restart can be invoked multiple, non-overlapping times. This allows the user to restart a previously running parallel job. SEE ALSO
