Oracle Grid Engine, previously known as Sun Grid Engine (SGE), CODINE (Computing in Distributed Networked Environments) or GRD (Global Resource Director), is an open source batch-queuing system, developed and supported by Sun Microsystems. Sun once also sold a commercial product based on SGE, known as N1 Grid Engine (N1GE).
Grid Engine was previously developed and supported by Sun Microsystems. Sun once also sold a commercial product based on SGE, known as N1 Grid Engine (N1GE). With the purchase of Sun by Oracle it was forked and there are currently three actively maintained forks: Univa Grid Engine, Son of Grid Engine and Scalable Grid Engine/Open Grid Scheduler.
Until recently Oracle offered a version known as Oracle Grid Engine but support has been transferred to Univa along with the copyrights and it is expected that the Oracle version will be folded into Univa Grid Engine. It was previously known as Sun Grid Engine (SGE), CODINE (Computing in Distributed Networked Environments) or GRD (Global Resource Director), and is an open source batch-queuing system,
The Scalable Grid Engine and Son of Grid Engine versions are open source and free to use under the Sun Industry Standards Source License.
The Univa Grid Engine and Oracle Grid Engine forks are proprietary and apart from time limited demo versions only available with a support contract.
Scalable Logic offers an optional support contract for the Scalable Grid Engine version.
SGE is typically used on a computer farm or high-performance computing (HPC) cluster and is responsible for accepting, scheduling, dispatching, and managing the remote and distributed execution of large numbers of standalone, parallel or interactive user jobs. It also manages and schedules the allocation of distributed resources such as processors, memory, disk space, and software licenses.
SGE is the foundation of the Sun Grid utility computing system, made available over the Internet in the United States in 2006, later becoming available in many other countries.
