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
