This merge adds Checkpoint/Restart support to Open MPI. The initial frameworks and components support a LAM/MPI-like implementation. This commit follows the risk assessment presented to the Open MPI core development group on Feb. 22, 2007. This commit closes trac:158 More details to follow. This commit was SVN r14051.

.SH DESCRIPTION
|
|
.ft R
|
|
\fIorte-clean\fR 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.
|
|
.sp
|
|
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.

.SH EXAMPLES

.ft R
|
|
Example 1: Clean up local node only.
|
|
.sp
|
|
.nf
|
|
example% orte-clean
|
|
.fi
|
|
.sp
|
|
|
|
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.
|
|
.sp
|
|
.nf
|
|
example% mpirun --pernode --host node1,node2,node3 orte-clean
|
|
.fi
|
|
.sp
|
|
To clean up on a specific set of nodes from a file.
|
|
.sp
|
|
.nf
|
|
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.
|
|
.sp
|
|
First, we see that we have two nodes with two CPUs each.
