The National E-Infrastructure Service (NES), formerly the National Grid Service, was an organisation for UK academics and researchers from 2004 through 2011. It was funded by two governmental bodies, Engineering and Physical Sciences Research Council (EPSRC) and the Joint Information Systems Committee (JISC). ==Description== The NES provided compute and data resources accessed through a standard common set of services.〔NES Minimum Software Stack, ''Wallom D, Oliver P, Richards A, Young S'', Version 3.2, ()〕 NES services are based on the Globus Toolkit for job submission and the Storage Resource Broker for data management. NES resources hosted scientific software packages, including SIESTA and Gaussian. As well as providing access to compute and data resources, the NES offered training (through the National e-Science Centre in Edinburgh)〔(National e-Science Centre )〕 and Grid support to all UK academics and researchers in grid computing. NES had more than 500 users〔(NES User Account System Metrics )〕 and twenty nine sites.〔(NES Resources )〕 The NES and GridPP were the two organisations that made up the (UK NGI ) the organisation which was the UK's point of contact with the European Grid Infrastructure. Prior to the NES, the UK e-Science programme funded a Grid Support Centre and later the Grid Operations Support Centre (GOSC). These provided support for end users to use and develop grid computing. Following the UK Engineering Task Force developing the so-called 'Level 2 Grid', which was an ''ad hoc'' collection of individual institutes committing a variety of compute resources for grid computing, the NES was funded to develop this into a full service. Initially called the ETFp Grid, or Engineering Task Force Production Grid, it became known as the National Grid Service. Hardware was purchased and installed by February 2004, and a web site appeared by April 2004.〔 During phase 1, from October 2004 to September 2006, it worked with the separately funded Grid Operations Support Centre (GOSC). By the start of phase two in October 2006, the NGS and the GOSC merged under the single project name NES. The NES had a third phase which ran through September 2011. 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「National Grid Service」の詳細全文を読む スポンサード リンク
