  3. 3. What is grid computing?What is grid computing? • Grid computing involves connecting geographically remote computers into a single network to create a virtual supercomputer by combining the computational power of all computers on grid.
  4. 4. • A network of geographically distributed resources including computers, peripherals, switches, instruments, and data. • Each user should have a single login account to access all resources. • Resources may be owned by diverse organizations

  6. 6. 66 The computing Grid approach Computing Grid System Users can access storage and computing resourcesUsers can access storage and computing resources coming from different (and heterogeneous) sourcescoming from different (and heterogeneous) sources The resources shared within the Grid can be physical objects (CPUs, storage devices) or logical resources (computing queues, distributed file systems)

  8. 8. Cousins of Grid ComputingCousins of Grid Computing  Distributed Computing  Peer-to-Peer Computing etc.  Distributed Computing Distributed computing is most often concerned with distributing the load of a program across two or more processes
  9. 9. PEER2PEER ComputingPEER2PEER Computing • Sharing of computer resources and services by direct exchange between systems. • Computers can act as clients or servers depending on what role is most efficient for the network.

  11. 11. Methods of Grid ComputingMethods of Grid Computing • Distributed Supercomputing • High-Throughput Computing • On-Demand Computing • Data-Intensive Computing • Collaborative Computing
  12. 12. Who Needs Grid Computing?Who Needs Grid Computing? • A chemist may utilize hundreds of processors to screen thousands of compounds per hour. • Teams of engineers worldwide pool resources to analyze terabytes of structural data. • Meteorologists seek to visualize and analyze data of climate with enormous computational demands.
  13. 13. Grid UsersGrid Users • Grid developers • Tool developers • Application developers • End Users • System Administrators
  14. 14. Grid DevelopersGrid Developers • Very small group. • Implementers of a grid “protocol” who provides the basic services required to construct a grid.
  15. 15. Tool DevelopersTool Developers • Implement the programming models used by application developers. • Implement basic services similar to conventional computing services: – User authentication/authorization – Process management – Data access and communication
  16. 16. Application DevelopersApplication Developers • Construct grid-enabled applications for end-users who should be able to use these applications without concern for the underlying grid. • Provide programming models that are appropriate for grid environments and services that programmers can rely on when developing (higher-level) applications.
  17. 17. System AdministratorsSystem Administrators • Balance local and global concerns. • Manage grid components and infrastructure. • Some tasks still not well delineated due to the high degree of sharing required.

  20. 20. Limitations of Grid ComputingLimitations of Grid Computing • Efforts are being made to standardize protocols. • Uses a command-line interface. • Requires programming in a language and using a host of libraries for interacting with Open Grid Services Infrastructure. • Our hope is to create an interface to Grid computing that accomplishes what Internet browsers (Netscape and Internet Explorer) did to open up the WWW
  21. 21. What’s Next?What’s Next? • More “filters” to transform data need to be developed and tested • Fancier graphics may be added to the GUIs • Extend Grid to include more software applications • Extend Grid services to other disciplines • Include industry and businesses as users and developers
  22. 22. CONCLUSIONCONCLUSION • Grid Computing involves cost savings, speed of computation, and agility. • The grid adjusts to accommodate the fluctuating data volumes that are a typical in the seasonal business.
