Son of Grid Engine is a highly-scalable and versatile distributed resource manager for scheduling batch or interactive jobs on clusters or desktop farms. It is a community project to continue Sun's Grid Engine. It is competitive against proprietary systems and provides better scheduling features and scalability than other free DRMs like Torque, SLURM, Condor, and Lava.
Open Grid Scheduler/Grid Engine is a batch-queuing system for distributed resource management. It is used by many high-performance clusters and computation farms. Together with basic batch job scheduling, it supports advance reservation, array jobs, parallel make, parallel job management, and GPU management.
