Grid Computing - Collection of computer resources from multiple locations

  1. 1. Presented by : Dibyadip Das Dnyaneshwar Magar February 20, 2014 Grid Computing 1
  2. 2. What Grid Computing is • Allows sharing and coordinated use of diverse resources in dynamic, distributed “virtual organizations”. Grid Computing 2
  3. 3. Electrical Power Grid Analogy Electrical power grid • users (or electrical appliances) get access to electricity through wall sockets with no care or consideration for where or how the electricity is actually generated. • “The power grid” links together power plants of many different kinds The Grid • users (or client applications) gain access to computing resources (processors, storage, data, applications, and so on) as needed with little or no knowledge of where those resources are located or what the underlying technologies, hardware, operating system, and so on are • "the Grid" links together computing resources (PCs, workstations, servers, storage elements) and provides the mechanism needed to access them. Grid Computing 3
  4. 4. Why need Grid Computing? • Core networking technology now accelerates at a much faster rate than advances in microprocessor speeds • Exploiting under utilized resources • Parallel CPU capacity • Virtual resources and virtual organizations for collaboration • Access to additional resources Grid Computing 4
  5. 5. Who needs Grid Computing? • Not just computer scientists… • scientists “hit the wall” when faced with situations: – The amount of data they need is huge and the data is stored in different institutions. – The amount of similar calculations the scientist has to do is huge. • Other areas: – – – – – Government Business Education Industrial design …… Grid Computing 5
  6. 6. Types of resources • Computation • Storage • Communications • Software and licenses • Special equipment, capacities, architectures, and policies Grid Computing 6
  7. 7. Job Scheduling Grid Computing 7
  8. 8. Security • Access policy - What is shared? Who is allowed to share? When can sharing occur? • Authentication - How do you identify a user or resource? • Authorization -How do you determine whether a certain operation is consistent with the rules? Grid Computing 8
  9. 9. Grid Security Model Grid Computing 9
  10. 10. Grid User Roles ---A User’s Perspective • Enrolling and installing grid software • Logging onto the grid • Queries and submitting jobs • Data configuration • Monitoring progress and recovery • Reserving resources Grid Computing 10
  11. 11. Grid User Roles ---An Administrator’s Perspective • Planning • Installation • Managing enrollment of donors and users • Certificate authority • Resource management • Data sharing Grid Computing 11
  12. 12. Grid Architecture GRI D Application Internet Collective Application Resource Connectivity Transport Fabric Internet Link Grid Computing 12
  13. 13. Grid Architecture • Fabric layer: Provides the resources to which shared access is mediated by Grid protocols. • Connectivity layer: Defines the core communication and authentication protocols required for grid-specific network functions. • Resource layer: Defines protocols, APIs, and SDKs for secure negotiations, initiation, monitoring control, accounting and payment of sharing operations on individual resources. • Collective Layer: Contains protocols and services that capture interactions among a collection of resources. • Application Layer: These are user applications that operate within VO environment. Grid Computing 13
  14. 14. Key Components • Portal/user interface Grid Computing 14
  15. 15. Grid Portal • Provides uniform access to the grid resources. For example, capabilities for Grid Computing resource authentication, remote resource access, scheduling capabilities, and monitoring status information. Grid Computing 15
  16. 16. Key Components • Security – Grid Security Infrastructure (GSI) Grid Computing 16
  17. 17. Key Components • Broker – Monitoring and Discovery Service (MDS) Grid Computing 17
  18. 18. Broker • It provides pairing services between the service requester and the service provider. • This pairing enables the selection of best available resources from the service provider for the execution of a specific task Grid Computing 18
  19. 19. Key Components • Scheduler Grid Computing 19
  20. 20. Scheduler • Schedulers are types of applications responsible for the management of jobs. • Allocation of resources needed for any specific job. • Partitioning of jobs to schedule parallel execution of tasks, data management Grid Computing 20
  21. 21. Globus Toolkit 4 Grid Computing 21
  22. 22. Online Access to Scientific Instruments Advanced Photon Source wide-area dissemination real-time collection archival storage desktop & VR clients with shared controls tomographic reconstruction DOE X-ray October 12, 2001 grand Intro to Grid ComputingUSC/ISI, NIST, U.Chicago challenge: ANL, and 22 Globus Toolkit™
  23. 23. Applications • The Southern California Earthquake Center uses Globus software to visualize earthquake simulation data. Grid Computing 23
  24. 24. Applications • Scientists in the Earth System Grid (ESG) are producing, archiving, and providing access to climate data that advances our understanding of global climate change. ESG uses Globus software for security, data movement, and system monitoring. Grid Computing 24
  25. 25. Applications • Globus Toolkit-driven Grid computing is central to management of large datasets generated by colliders such as those at CERN. This simulation shows two colliding lead ions just after impact, with quarks in red, blue, and green and hadrons in white. Grid Computing 25
  26. 26. Prospect of Grid computing • The Grid aims ultimately to turn the global network of computers into one vast computational resource. • Related to many areas in computer science • Being developed by hundreds of researchers and software engineers around the world. • Still “work in process” • Potentially revolutionary.
