Adding Sun HPC ClusterTools Support

Once the basic integration between Sun Grid Engine and Globus is successfully completed, both Sun Grid Engine and Globus can be further customized to support MPI parallel jobs using Sun HPC ClusterTools software.

The first step for the customization is to create connection between Sun Grid Engine and Sun HPC ClusterTools software. This integration can be accomplished by an easy integration script with accompanied scripts for job controls. The integration package is contained in the "Grid Engine common files" package since 5.3 beta2 in the $SGE_ROOT/mpi/sunhpc/loose-integration/ subdirectory. Please click here to download the package.

The second step is to modify Globus environment to support Sun MPI job submission through the Globus command. This involves a couple of step as shown below (Globus version 1.x).

Add "jobmanager-sge" service
Copy GRAM SGE scripts into the deploy directory

Note: The GRAM scripts are customized based on the fact that the default install configuration of SGE and the default integration between SGE and Sun HPC ClusterTools are used.

The following shows an example to submit an Sun MPI job to Sun Grid Engine through Globus. As discussed above, the submission is based on the default integration between Sun Grid Engine and Sun HPC ClusterTools. The job requests two MPI processes.

With the new GRAM scripts for SGE:

globusrun -r "hpc-node1.sun.com:2119/jobmanager-sge:" \
'&(jobtype=mpi) \
(directory=/home/byun/projects/JMS/Globus/ex03) \
(executable=/home/byun/projects/JMS/Globus/ex03/monte) \
(stdout=/home/byun/projects/JMS/Globus/ex03/ex03-output) \
(stderr=/home/byun/projects/JMS/Globus/ex03/ex03-error) \
(environment=(SGE_PE hpc) (SGE_CRE cre)) \
(count=2)'
