What is Grid &What should Grid do Sheng JIANG Net & Reading Group CS – UCL Networks Research Group, CS – UCL
Grid Introduction • The Grid computing is originally raised by physics, which requires large computation • The Grid refers to an infrastructure that enables the integrated, collaborative use of high-end computers, networks, databases, and scientific instruments owned and managed by multiple organizations • Grid applications often involve large amounts of data and/or computing and often require secure resource sharing across organizational boundaries Networks Research Group, CS – UCL
Grid Problems • Coordinated resource sharing and problem solving in dynamic, multi-institutional virtual organizations • Dynamically configuration • Highly controllable • Sharing policy and mechanisms • Much more interoperation Networks Research Group, CS – UCL
Grid vs.Other Technologies (1) • Conventional Distributed Computing • Not provide a general resource-sharing framework for VO requirements • World Wide Web • Ubiquity • Attractive platform for constructing VO • Lacks features required for the richer interaction Networks Research Group, CS – UCL
Grid vs.Other Technologies (2) • Virtual Private Network • Not extend dynamically to encompass other resource • Not provide the resource control and management • Peer-to-Peer and Internet Computing • More in common • Focus on vertically integrated solution Networks Research Group, CS – UCL
Layered Grid Architecture Networks Research Group, CS – UCL
Grid Functionalities • Secure communication • With easy access • Balance with performance • Large data transfer • Resources and services discovery • Tasks and instances scheduling • Remote access and management • Upgradeability and transport protocols • Self recovery Networks Research Group, CS – UCL
What could Grid do • Multiple domain integrated services and user interfaces • Friendly user interface for end users, even administrators • Mobility support • More… Networks Research Group, CS – UCL
