GLOBUS TOOLKIT

History of Globus

The first version, Globus v1.0, ran on about 10 different operating systems, from Windows to Cray, and maintenance was a nightmare.

A few years later, the second evolution of Globus Toolkit (GT2) arrived. While several APIs and interfaces looked the same, the internals were to a large extent rewritten.

The evolution GT4, what is the difference in security.

Actual simulation code may be stored in repositories under the control of the author, while the computers being used to execute these codes may be located within a national facility

Grid infrastructure furnishes the fundamental services needed to locate, access, and manage shared resource

Much like TCP/IP and DNS provide the basic services on which can be built higher-level capabilities, such as the World Wide Web, Globus services are designed to provide the low-level mechanisms on which higher level, domain specific services are constructed.

Summary about Grid Computing

Grid is not the Holy Grail of implementing algorithms

Grid computing is relatively cheap since the ability to support computation across administrative domains sets
