What Is Grid Computing?

What is Grid Computing

• Emerging computing model that provides the
  ability to perform higher throughput computing by
  taking advantage of many networked computers to
  model a virtual computer architecture that is
  able to distribute process execution accross a
  parallel infra-structure.

What is Grid Computing

• Heterogeneous and Distributed enviroment
• It is NOT a cluster architecture!

7
Parts of Grid Computing

• Infrastructure Grid
• Hardware resources such as processors, storage
  and network
• Applications Grid
• Packaged or custom applications used for
  business logic and process flow within
  application software

Goals of Grid Computing
10
Goals Of Grid Computing

• Pervasive, uniform, and reliable access to data,
  storage capacity and computation power
• Resource utilization
• Delivery of computer power as a utility. (City
  Water, electricity systems)

Examples of Grid Computing
17
Examples Of Grid Systems

• Seti_at_Home is the most popular(1st).
• Climateprediction, Einstein_at_Home etc.
• All uses BOINC software
• Over 18 projects working using BOINC

Examples (Continued...)

• Enterprise grids
• Oracle grid
• Blade Servers
• Sun

20
Oracle uses grid Structure
21
Blade Servers

• For power, heat and space savings
• Includes processors, memory, network cards and
  storage

22
Grid Softwares
23
Grid Softwares

• Globus Management Software
• Java Technology Custom programming

24
Globus Grid Management Software
25
Globus Grid Management Software

• Product for managing grids
• Supported by many large vendors
• GRAM Grid Resource Allocation Manager
• gatekeeper process that controls execution of
  job managers
• MDS Monitoring and Directory Service
• GRIS (Grid Resource Information Service) collects
  local info
• GIIS (Grid Index Information Service) collects
  GRIS info
• GASS (Global Access to Secondary Storage)

26
Java Technology
27
Java Technology

• RMI, Web Services and JNDI
• RMI Remote Method Invocation
• Web Services Software As Services, Soap
  Packages over HTTP
• Orchestration of Services
• E-commerce, Online Community Servers
• J2EE Application Servers gt Load Balancing, Fail
  Over mechanisms

28
Application Suitability
29
Application Suitability

• For a grid system to perform applications must
  have some criteria.
• Best Suitable gt Large Batch jobs that requires
  minimum inter process communication and
  synchronization

30
Academic Researches
31
Academic Researches

• In 2004, Genaud Algorithm for load balancing.
• Allock Et. Al. Data transfer problem in high
  performance grid environments. (Replica
  management Service that uses an FTP-like protocol
  to make replicas of data elements accross the
  grid to improve performance)

32
Conclusion
33
Conclusion

• In summary, Grid computing is cooperation of
  different computers, for a specific task, so that
  the user acquires better performance for that
  specific task.
• The Load is on remote machines rather than
  clients.
• Like Transfer of CPU power as electricity power.
