GRID COMPUTING: STATE OF THE ART REPORT 10.28.02
By Mark Baker, Rajkumar Buyya, and Domenico Laforenza GRIDtoday
==============================================================================

The last decade has seen a substantial increase in commodity computer and
network performance, mainly as a result of faster hardware and more
sophisticated software.

Nevertheless, there are still problems, in the fields of science, engineering,
and business, which cannot be effectively dealt with using the current
generation of supercomputers. In fact, due to their size and complexity, these
problems are often very numerically and/or data intensive and consequently
require a variety of heterogeneous resources that are not available on a
single machine.

A number of teams have conducted experimental studies on the cooperative use
of geographically distributed resources unified to act as a single powerful
computer. This new approach is known by several names, such as metacomputing,
scalable computing, global computing, Internet computing, and more recently
peer-to-peer or Grid computing.

The early efforts in Grid computing started as a project to link
supercomputing sites, but have now grown far beyond their original intent. In
fact, many applications can benefit from the Grid infrastructure, including
collaborative engineering, data exploration, high- throughput computing, and
of course distributed supercomputing.

Moreover, due to the rapid growth of the Internet and Web, there has been a
rising interest in Web-based distributed computing, and many projects have
been started and aim to exploit theWeb as an infrastructure for running
coarse-grained distributed and parallel applications.

In this context, the Web has the capability to be a platform for parallel and
collaborative work as well as a key technology to create a pervasive and
ubiquitous Grid-based infrastructure. This paper aims to present the state-of-
the-art of Grid computing and attempts to survey the major international
efforts in developing this emerging technology.
