Grid computing ppt 2003(done)

  1. 2. <ul><li>What is the Grid? </li></ul><ul><li>Grid is an infrastructure, which allows integrated, collaborative use of geographically separated, autonomous resources. </li></ul><ul><li>Integrate networking, communication, computation and information toprovide a virtual platform in the same way </li></ul>
  2. 3. <ul><li>Grid Computing is a type of parallel and distributed system that enables the sharing, selection, and aggregation of geographically distributed &quot;autonomous&quot; resources dynamically at runtime depending on their availability, capability, performance, cost, and users' quality-of-service requirements </li></ul><ul><li>Grid computing is all about achieving greater performance and throughput by pooling resources on a local, national, or international level . </li></ul>
  3. 5. <ul><li>A Grid… </li></ul><ul><li>… coordinates resources, which aren’t subordinated to a central authority ... </li></ul><ul><li>... and uses open, standard protocols and interfaces, </li></ul><ul><li>... to provide not trivial qualities of services . </li></ul>CHARACTERISTICS OF GRID SYSTEM
  4. 6. <ul><li>TYPES OF GRID </li></ul><ul><li>Computational Grid -computing power </li></ul><ul><li>Scavenging Grid -desktop machines </li></ul><ul><li>Data Grid -data access across multiple organizations </li></ul>
  5. 7. Scavenging Grid Computational Grid Data Grid
  6. 8. PROS AND CONS Money Saving Schedule Problem (Who, When?) Space Saving Security Problem (Data is Remote) Resource Saving Resource Management (Who is Prior?) Time Saving CONS PROS
  7. 10. <ul><li>Grids are about large-scale resource sharing . </li></ul><ul><ul><li>Spanning administrative boundaries. </li></ul></ul><ul><ul><ul><li>Central processors, storage, network bandwidth, databases, applications, sensors and so on </li></ul></ul></ul><ul><li>Problem solving in dynamic, multi-institutional environment . </li></ul><ul><li>Organizing geographically distributed computing resources </li></ul><ul><ul><li>So that they can be flexibly and dynamically allocated and accessed </li></ul></ul><ul><li>Providing such capabilities, where Sharing is highly controlled, clear definitions of exactly what is shared, who is allowed to share, and the conditions under which sharing occurs. </li></ul>
  8. 12. <ul><li>IMPORTANCE OF GRID COMPUTING </li></ul><ul><li>Flexible, Secure, Coordinated resource sharing. </li></ul><ul><li>Virtualization of distributed computing resources. </li></ul><ul><li>Give worldwide access to a network of distributed resources. </li></ul>
  9. 13. <ul><li>GRID REQUIREMENTS </li></ul><ul><li>Security </li></ul><ul><li>Resource Management </li></ul><ul><li>Data Management </li></ul><ul><li>Information Services </li></ul><ul><li>Fault Detection </li></ul><ul><li>Portability </li></ul>
  10. 14. <ul><li>Resource sharing </li></ul><ul><ul><li>Computers, data, storage, sensors, networks, … </li></ul></ul><ul><ul><li>Sharing always conditional: issues of trust, policy, negotiation, payment, … </li></ul></ul><ul><li>Coordinated problem solving </li></ul><ul><ul><li>Beyond client-server: distributed data analysis, computation, collaboration, … </li></ul></ul><ul><li>Dynamic, multi-institutional virtual organizations </li></ul><ul><ul><li>Community overlays on classic org structures </li></ul></ul><ul><ul><li>Large or small, static or dynamic </li></ul></ul>
  11. 15. Science Today is a Team Sport!!
  12. 16. <ul><li>Used in an innovative way in a wide variety of areas including inventory control, enterprise computing, games, etc. </li></ul><ul><li>The Entropia system of peer-peer or Mega computing </li></ul><ul><li>[email_address] </li></ul><ul><li> is being developed by the UK e-Science program </li></ul>
  13. 17. e-Science scenario
  14. 18. <ul><li>How will grids will impact your everyday life? Who could imagine? Consider the following predictions about the future </li></ul><ul><li>&quot;The world will only need five computers&quot; (attributed to Thomas J. Watson, IBM )   </li></ul><ul><li>640 kilobytes is all the memory you will ever need&quot; ( attributed to Bill Gates, Microsoft) &quot;There is absolutely no need for a computer in the home&quot; (attributed to Ken Olsen, DEC)(once a leading minicomputer manufacturer) </li></ul>
  15. 19. <ul><li>Grid Computing is becoming the platform for next generation escience experiments. </li></ul><ul><li>Grid computing is cooperation of different computers, for a specific task, so that the user acquires better performance for that specific task . </li></ul>
  16. 20. <ul><li>Davies, Antony (June 2004). &quot;Computational Intermediation and the Evolution of Computation as a Commodity“. </li></ul><ul><li>&quot;What is the Grid? A Three Point Checklist&quot;(PDF). </li></ul><ul><li>&quot;Anatomy of the Grid&quot;(PDF). </li></ul>
