Oracle Grid Engine,〔(【引用サイトリンク】title=Oracle Grid Engine )〕 previously known as ''Sun Grid Engine'' (SGE), CODINE (Computing in Distributed Networked Environments) or GRD (Global Resource Director),〔(【引用サイトリンク】title=A Little History Lesson )〕 was a grid computing computer cluster software system (otherwise known as batch-queuing system), acquired as part of a purchase of Terraspring,〔http://www.bizjournals.com/sanfrancisco/stories/2002/11/11/daily85.html〕 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.〔http://www.crn.com/news/channel-programs/18838567/sun-acquires-terraspring-to-bolster-n1-strategy.htm〕 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.〔(【引用サイトリンク】title=Univa Completes Acquisition of Grid Engine Assets, Becoming the Sole Commercial Provider of Grid Engine Software )〕 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.〔(【引用サイトリンク】title=The Grid Engine Source License )〕 Those projects were forked from the original project code and are known as Son of Grid Engine〔(【引用サイトリンク】title=Son of Grid Engine )〕 and Open Grid Scheduler.〔(【引用サイトリンク】title=Open Grid Scheduler )〕 Grid Engine 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. Grid Engine used to be the foundation of the Sun Grid utility computing system, made available over the Internet in the United States in 2006,〔(【引用サイトリンク】title=World's First Utility Grid Comes Alive on the Internet )〕 later becoming available in many other countries and having been an early version of a public Cloud Computing facility predating Amazon AWS, for instance. ==Features== The below feature sets date from the last Sun releases in 2009 or earlier. More current feature information can be found on the web sites of the open source forks or for Univa Grid Engine. Features in 6.2: * Advance reservation * Array job interdependencies * Rule-based ''Resource Quota'' control〔(Specification: Resource Quota )〕 * Enhanced remote execution (without using external rshd/rlogind/sshd processes) * Multi-clustering〔(【引用サイトリンク】 Hedeby Project home )〕 * 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''〔(【引用サイトリンク】 xml-qstat )〕 web interface * Parallel jobs (MPI, PVM, OpenMP), and scalable parallel job startup with qrsh〔(【引用サイトリンク】 Long delay when submitting large jobs (mailing list message) )〕 * Usage accounting * Accounting and Reporting COnsole (ARCO) * parallel make: distmake, dmake (Sun Studio), and SGE's own qmake * FLEXlm integration〔(【引用サイトリンク】 flex-grid )〕〔(【引用サイトリンク】 Olesen-FLEXlm-Integration )〕 and multi-cluster software license management with ''LicenseJuggler''〔(【引用サイトリンク】 LicenseJuggler )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oracle Grid Engine」の詳細全文を読む スポンサード リンク
