e-Science Update Steve Gough, ITS 19 Feb 2007
e-Science • large scale science increasingly carried out through distributed global collaborations • enabled by the Internet • access to very large data collections • very large scale computing resources • high performance visualisation Ne. SC web site, in turn taken from the Research Council e-Science Core Programme 20 Feb 2007 e-Science Update 2
e-Science • easy access to expensive remote facilities – computing resources • dedicated Teraflop computers or cheap collections of PCs – information stored in dedicated databases Ne. SC web site, in turn taken from the Research Council e-Science Core Programme 20 Feb 2007 e-Science Update 3
The Grid • an architecture proposed to bring all these issues together • the Grid as an enabler for Virtual Organisations – "An infrastructure that enables flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions and resources. " • Ian Foster and Carl Kesselman – inventors of the Globus approach to the Grid 20 Feb 2007 e-Science Update Ne. SC web site, in turn taken from the Research Council e-Science Core Programme 4
Study of Users' Priorities for EInfrastructure for Research • SUPER • continuing study by staff from: – National e-Science Centre (Ne. SC) – Open Middleware Infrastructure Institute UK (OMII-UK) – Council for the Central Laboratory of the Research Councils (CCLRC) 20 Feb 2007 e-Science Update 5
SUPER • found 5 main issues with existing users: – distributed file management and policy – tools to support the creation and use of dynamic virtual organisations – need to support projects through tools and training – authentication, software licensing, and reliable and consistent environments – user interaction with e-infrastructure services through defined APIs, scripting environments, and graphical workflow environments 20 Feb 2007 e-Science Update 6
e-Science Development Officer • stimulate research collaboration – within Reading and between Reading & other institutions • • maximise use of developing resources work with academics based in ITS, but work with existing experts • SSE, ESSC, ACET, Meteorology etc • closing date 2/3/07 20 Feb 2007 e-Science Update 7
National Grid Service (NGS) • mission: – to provide coherent electronic access for UK researchers to all computational and data based resources and facilities required to carry out their research, independent of resource or researcher location – http: //www. grid-support. ac. uk/ 20 Feb 2007 e-Science Update 8
National Grid Service (NGS) – 2 compute nodes • Oxford & White Rose Grid – 2 data nodes • Manchester & RAL 20 Feb 2007 e-Science Update 9
Reading Grid • 200+ classroom PCs running Co. Linux image • using spare CPU power • PCs join a condor pool of local computers • joining Reading & Oxford Grids? • can we add PCs in schools? • more from Ian Bland later 20 Feb 2007 e-Science Update 10
Reading e-Science Centre (Re. SC) • promote e-Science methods in the environmental science community • http: //www. resc. rdg. ac. uk/ • more from Jon Blower. . . 20 Feb 2007 e-Science Update 11
