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
