Cluster computing2

  1. 1. CLUSTER COMPUTING GHANSHYAM ANAND
  2. 2. <ul><li>Is a group of tightly coupled computer working together closely </li></ul><ul><li>Clusters are commonly connected through fast LAN (Local Area Network) </li></ul><ul><li>Cluster have evolved to support application where the huge database is required </li></ul>INTRODUCTION
  3. 3. <ul><li>First commodity clustering product was </li></ul><ul><li>ARC net ,developed by DATA point in </li></ul><ul><li>1977 </li></ul><ul><li>The next product was VAX cluster, released by DEC in 1980 </li></ul>HISTORY
  4. 4. <ul><li>Microsoft , Sun Microsystems ,and other leading hardware and software companies offer clustering packages </li></ul>
  5. 5. <ul><li>Price/Performance </li></ul><ul><li>Reason for the growth in use of Clusters is that they have significantly reduced the cost of processing power </li></ul><ul><li>Availability </li></ul><ul><li>Single points of failure can be eliminated, </li></ul><ul><li>If any one system component goes down, </li></ul><ul><li>The System as a whole stay highly available </li></ul>WHY CLUSTER
  6. 6. <ul><li>Scalability </li></ul><ul><li>Cluster can grow in overall capacity because processors and nodes can be added as demand increases </li></ul>
  7. 7. <ul><li>A Cluster is a type of parallel/distributed processing system, which consist of a collection interconnected stand alone computers (Node) working together </li></ul><ul><li>NODE </li></ul><ul><li>A single or multiprocessor system with a memory, I/O facilities & O/S </li></ul><ul><li>Generally 2 or more nodes are connected together </li></ul>ARCHITRETURE
  8. 8. <ul><li>Appear as a single system to user and applications </li></ul><ul><li>Provide a cost-effective way to gain features and benefits </li></ul>
  9. 9. <ul><li>High Performance (HP) Clusters </li></ul><ul><li>Load Balancing Clusters </li></ul><ul><li>High Availability (HA) Clusters </li></ul>KINDS OF CLUSTERS
  10. 10. <ul><li>Start from 1994 </li></ul><ul><li>Donald Becker of NASA assembled this cluster. </li></ul><ul><li>Applications like data mining, simulations, parallel processing, weather modeling, etc </li></ul>HIGH PERFORMANCE CLUSTER
  11. 11. <ul><li>Large number of nodes to share load </li></ul><ul><li>from the user side they are multiple machine ,but function as single virtual machine </li></ul><ul><li>Commonly used with busy ftp and web servers with large client base </li></ul>LOAD BALANCING CLUSER
  12. 12. <ul><li>Avoid single point of failure </li></ul><ul><li>This requires at least two nodes - a primary and a backup. </li></ul><ul><li>Almost all load balancing cluster are with HA capability </li></ul>HIGH AVAILABILITY CLUSTER
  13. 13. <ul><li>Cluster Networking </li></ul><ul><li>Programming </li></ul><ul><li>Timing </li></ul><ul><li>Speed Selection </li></ul>ISSUES TO BE CONSIDERED
  14. 14. <ul><li>Clusters are promising </li></ul><ul><li>Solve parallel processing problems </li></ul><ul><li>New trends in hardware and software technologies are likely to make clusters </li></ul><ul><li>Clusters based supercomputers can be seen everywhere </li></ul>CONCLUSION
  15. 15. THANK YOU
