Oracle Grid Engine

Oracle Grid Engine, previously known as Sun Grid Engine (SGE), CODINE (Computing in Distributed Networked Environments) or GRD (Global Resource Director), was a grid computing computer cluster software system (otherwise known as batch-queuing system), acquired as part of a purchase of Terraspring, then improved and supported by Sun Microsystems and later Oracle. There have been open source versions and multiple commercial versions of this technology, initially from Sun, later from Oracle and then from Univa Corporation.

This technology forked from the same codebase as HP's UDC, and IBM's eLiza in 2002.

On October 22, 2013 Univa announced it acquired the intellectual property and trademarks for the Grid Engine technology and that Univa will take over support.

The original Grid Engine open-source project website closed in 2010, but versions of the technology are still available under its original Sun Industry Standards Source License. Those projects were forked from the original project code and are known as Son of Grid Engine and Open Grid Scheduler.
