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
