Conclusion
A tight integration between the RM and the parallel environment offers significant benefits over a loose integration. We have implemented a robust and open architecture in Sun CRE that enables tight integrations with multiple RMs, and we have used that architecture to provide tight integrations with the Sun Grid Engine system, PBS, and LSF. The architecture is extensible, so third parties can implement their own integration with their own favored RM. The architecture adds to a growing set of open interfaces in the HPC ClusterTools environment, making it an attractive foundation for building open and integratable HPC solutions.
The software described here is part of the Sun HPC ClusterTools 5 software release, which is available at:
