Sun Grid Engine (SGE), earlier known as CODINE (COmputing in DIstributed Networked Environments) or GRD (Global Resource Director) is an open source batch-queuing system, supported by Sun Microsystems. Sun also sells a commercial product based on SGE, known as N1 Grid Engine (N1GE).
Software like SGE is typically used on a computer farm or computer cluster and is responsible for accepting, scheduling, dispatching, and managing the remote 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 grid computing system, made available over the Internet in the United States in 2006. [1]

[edit] Features
Features of SGE include:
- Multiple advanced scheduling algorithms allow powerful policy-based resource allocation
- Cluster queues
- Job and scheduler fault tolerance
- Job Checkpointing
- Job arrays
- DRMAA (Job API)
- Resource reservation
- XML status reporting
- Usage accounting
- N1 Grid Engine 6 accounting and reporting (ARCO)
- Service Domain Management module in order to meet Service Level Objectives
- parallel make: distmake, dmake (Sun ONE Studio), and SGE's own qmake
A number of SGE add-ons are available:
- Grid Engine Portal (GEP)
- Transfer-queue over Globus (TOG)
- JOb Scheduling Hierarchically (JOSH)
SGE runs on multiple platforms, including:
- AIX
- BSD - FreeBSD, NetBSD, OpenBSD
- HP-UX
- IRIX
- Linux
- Mac OS X
- Solaris
- SUPER-UX
- Tru64
- Windows (as execution hosts only)
- Z/OS (in progress)
[edit] History
In 2000, Sun acquired Gridware, Inc. a privately owned commercial vendor of advanced computing resource management software with offices in San Jose, Calif., and Regensburg, Germany.[2] Later that year, Sun offered a free version of Gridware for Solaris and Linux, and renamed the product Sun Grid Engine.
In 2001, Sun made the source code available [3], and adapted the open source development model. Ports for MacOSX and *BSD were contributed by the non-Sun open source developers.
