Oracle Grid Engine, previously known as Sun Grid Engine (SGE), previously known as 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 is open source and free to use from the project website under the Sun Industry Standards Source License. There is a commercial version available from the Oracle site. It appears that all further versions, starting from 6.2u6, will be commercial (with a 90-day free trial)
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.

Famous quotes containing the words oracle and/or engine:
“There be three things which are too wonderful for me, yea, four which I know not: the way of an eagle in the air; the way of a serpent upon a rock; the way of a ship in the midst of the sea; and the way of a man with a maid.”
—Bible: Hebrew Proverbs, 30:18-19.
From the oracle of Agur, son of Jakeh.
“The machine unmakes the man. Now that the machine is perfect, the engineer is nobody. Every new step in improving the engine restricts one more act of the engineer,—unteaches him.”
—Ralph Waldo Emerson (1803–1882)
