|Stable release||6.2u5 / December 22, 2009|
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 also sells a commercial product based on SGE, also known as N1 Grid Engine (N1GE).
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.
Features new in version 6.2
- Advance reservation
- Array job interdependencies
- Enhanced remote execution (without using external rshd/rlogind/sshd processes)
- Multi-clustering 
- Daemons managed by the Service Management Facility on Solaris
- Pseudo TTY (pty) support for interactive jobs
- Job Submission Verifier (client-side and server-side job verification)
- GUI Installer and SGE Inspect
- Topology-aware scheduling and thread binding
- Hadoop integration, Amazon EC2 integration for cloud computing
Other features of SGE include:
- Multiple advanced scheduling algorithms allow powerful policy-based resource allocation
- Cluster queues
- Job and scheduler fault tolerance - Grid Engine continues to operate as long as there is one or more hosts available
- Job checkpointing
- Job arrays and job tasks
- DRMAA (Job API)
- Resource reservation
- XML status reporting (qstat and qhost), and the xml-qstat web interface
- Parallel jobs (MPI, PVM, OpenMP), and scalable parallel job startup with qrsh 
- Usage accounting
- Accounting and Reporting COnsole (ARCO)
- parallel make: distmake, dmake (Sun Studio), and SGE's own qmake
- FLEXlm integration  and multi-cluster software license management with LicenseJuggler 
SGE runs on multiple platforms, including:
- BSD - FreeBSD, NetBSD, OpenBSD
- Mac OS X
- Windows via SFU(Interix) or SUA(Microsoft Windows Services for UNIX) (as execution hosts only)
- Z/OS (in progress)
A typical Grid Engine cluster consists of a master host, and one or more execution hosts. Moreover, multiple shadow masters can be configured as hot spares, which take over the role of the master when the original master host crashes.
Support and training
Sun provides support contracts  for the commercial version of Grid Engine on most UNIX platforms and Windows. Professional services, consulting, training, and support are also provided by Sun Partners.  Sun partners with Georgetown University to deliver Grid Engine administration classes. The Bioteam runs short SGE training workshops that are 1 or 2 days long.
Users can obtain community support on the Grid Engine mailing lists.
Notable deployments of SGE include:
- Sun Grid
- the TSUBAME supercomputer at the Tokyo Institute of Technology, which was number 7 on June 2006 TOP500 list.
- Ranger at the Texas Advanced Computing Center (TACC). Ranger has 62,976 processor cores in 3,936 nodes and a peak performance of 504TFlops.   Ranger is currently the 6th most powerful TOP500 supercomputer. 
- San Diego Supercomputer Center (SDSC)
- Geophysical Fluid Dynamics Laboratory (NOAA GFDL)
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. Later that year, Sun offered a free version of Gridware for Solaris and Linux, and renamed the product Sun Grid Engine.
Other Grid Engine based products
- Sun Constellation System
- Sun Visualization System
- Sun Compute Cluster 
- ClusterVisionOS Distribution
- Rocks Cluster Distribution
- EGEE 
- Univa UD's UniCluster Express
- BioTeam's iNquiry
A number of SGE add-ons are available:
- Solaris Cluster integration 
- Service Domain Management module in order to meet service level objectives
- Transfer-queue Over Globus (TOG). Globus does not officially support SGE, but the London e-Science Center has created a package and provides instructions on how to configure a Globus Toolkit server so that it can submit jobs for execution on a local Sun Grid Engine installation.
