GRID COMPUTING

• Today's science is much based on computation,
  data analysis, and collaboration as on the
  efforts of individual experimentalists and
  theorists.
• Grid computing is the application of several
  computers to a single problem at the same time.
• Grid computing depends on software to divide and
  apportion pieces of a program among several
  computers.

• In case of clusters, the resource allocation is
  performed by a centralised resource manager and
  all nodes cooperatively work together as a single
  unified resource. In case of Grids, each node has
  its own resource manager and do not aim for
  providing a single system view.
• One of the major disadvantages of this feature is
  that the computers which are actually performing
  the calculations might not be entirely
  trustworthy.

How grid computing works

The following are the major business areas for
grid computing

• Life sciences analyze biological and chemical
  information.
• Financial services- for complex financial models.
• Higher education data and computation-intensive
  research.
• Engineering services collaborative design and
  data-intensive testing.
• Government collaboration and agility in both
  civil and military departments
