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
