  1. CLUSTER COMPUTING A Seminar on Presented by : Name – Balvant V. Biradar Roll No. – 001 Class – M.Sc. C.S. – S.Y. (IV - Semester)

  2. This Seminar Covers… • Introduction to Cluster Computing • Types of Clusters • Cluster Components • Cluster Operation • Cluster Applications • References

  3. ABSTRACT • A computer cluster is a group of linked computers, working together closely so that in many respects they form a single computer • The major objective in the cluster is utilizing a group of processing nodes so as to complete the assigned job in a minimum amount of time by working cooperatively. The main and important strategy to achieve such objective is by transferring the extra loads from busy nodes to idle nodes. • The seminar will contain the concepts of cluster computing and the principles involved in it.

  4. Introduction • Background Study • Super , Mainframe computers are not cost effective • Cluster technologies have been developed that allow multiple low cost computers to work in a coordinated fashion to process applications • These are cost effective and provides performance and flexibility

  5. What is cluster computing • Cluster computing is best characterized as the integration of a number of off-the-shelf commodity computers and resources integrated through hardware, networks, and software to behave as a single computer

  6. Cluster Benefits • Scalability, a cluster uses the combined processing power of compute nodes to run cluster-enabled applications • Availability, within the cluster is assured as nodes within the cluster provide backup to each other in the event of a failure • Performance, an additional benefit comes with the existence of a single system image and the ease of manageability of the cluster

  7. TYPES OF CLUSTER • High Availability or Failover Clusters • designed to provide uninterrupted availability of data or services to the end-user community • Used to implement database, mail, file print, web application servers.

  8. TYPES OF CLUSTER cont.. • Load Balancing Cluster • distributes incoming requests for resources or content among multiple nodes running the same programs or having the same content

  9. TYPES OF CLUSTER cont.. • Parallel/Distributed Processing Clusters • A parallel cluster is a system that uses a number of nodes to simultaneously solve a specific computational or data-mining task • typically used for- mathematical computation, scientific analysis and financial data analysis

  10. CLUSTER COMPONENTS • The basic building blocks of clusters are broken down into multiple categories: the cluster nodes, cluster operating system, network switching hardware and the node/switch interconnect

  11. CLUSTER OPERATION • Cluster Nodes: • migrated from the conventional tower cases to single rack-unit multiprocessor systems • responsible for running the file system and also serves as the key system

  12. CLUSTER OPERATION Cont… • Cluster Network: • availability of high speed, low-latency network switch technologies that provide the inter-nodal communications • Network Characterization: Two primary Characteristics – bandwidth and delay, • Ethernet, Fast Ethernet, Gigabit Ethernet and 10-Gigabit Ethernet

  13. CLUSTER OPERATION Cont… • Cluster Applications: • Parallel applications exhibit a wide range of communication behaviours and impose various requirements on the underlying network • Compute Intensive Applications: applies to any computer application that demands a lot of computation cycles, are very sensitive to end-to-end message latency • Data or I/O Intensive Applications: applies to any application that has high demands of attached storage facilities • Transaction Intensive Applications: applies to any application that has a high-level of interactive transactions between an application resource and the cluster resources

  14. CLUSTER OPERATION Cont… • Message Latency: • defined as the time it takes to send a zero-length message from one processor to another (in ms) • is made up of aggregate latency incurred at each element within the cluster network, including within the cluster nodes themselves

  15. CLUSTER OPERATION Cont… • CPU Utilization: • To use computer resources as efficiently as possible

  16. CLUSTER APPLICATIONS • Few important cluster applications are: • Google Search Engine. • Petroleum Reservoir Simulation. • Protein Explorer. • Earthquake Simulation. • Image Rendering.
