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
       processes 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
