What is Grid?
The "grid" often means "grid environment", which is a circumstance that multiple resources distributed over global network (WAN) are used simultaneously. Grid environment works as infrastructure for various activities using multiple resources over global network, such as computation using remote computers, tele-communication with friends over the Internet, and so on.
What is Grid computing?
"Grid computing" is one of the situations using grid, and it aimes at constructing large and high performance computation environment.
Why Grid computing?
In recent years, more and more high performance computers work in all over the world. Since, in grid computing, such computers will be used simultaneously, high computation performance will be achived with taking less costs than building a new supercomputer. So grid computing attracts attention as a next generation of efficient computational infrastructure for various science technologies.
