As part of the mpirun task submitted, the following flags are commonly used with mpirun:
-ccp Automatically creates an appfile which matches the CCP job allocation. The
number of ranks run will equal the number of processors requested.
-nodex When used in conjunction with the -ccp flag, will run one rank per node in
the CCP job allocation. (i.e. number of ranks equals number of nodes, one
rank per node.)
-netaddr XX.XX.XX.XX
Specifies the TCP network to use.
-TCP or -IBAL Specifies the network protocol to use.
Verify that rank.exe is on a shared directory.
Below are some useful CCP environment variables for naming the job name or stdout/err
fileshare:
• CCP_CLUSTER_NAME - Cluster name
• CCP_JOBID - Job ID
• CCP_JOBNAME - Job name
• CCP_TASKCONTEXT - Task ‘content’ (jobid.taskid)
• CCP_TASKID - Task ID
Included in the help directory is an example template (.xml file). To use this template, change
the processor count on the Submit Jobs window, Processors tab, and edit the Tasks
command to include flags and the rank executable. The job will run with ranks being equal to
the number of processors, or the number of nodes if the -nodex flag is used.
Submitting jobs from the CCS GUI
To execute an HP-MPI job from the CCS GUI:
1. Bring up the Compute Cluster Job Manager. If it asks for the cluster name, give it the
name of the head node. If running on the Compute Cluster Job Manager from the head
node, select localhost.
2. Select File->Submit Job. This will bring up the Submit Job window.
