1 Introduction
Grid computing has emerged as an important field synonymous to high
throughput computing (HTC) [1].
Contrary to other systems where the focus
is to achieve greater performance measured in terms of the number of floating
point operations the system can perform per minute, the importance of grids
is defined in terms of the amount of work they are able to deliver over a period of time.
The difference between high performance computing and high
throughput computing has been illustrated by the Condor project [2].
Grids
cannot be considered as a revolutionary technology.
Rather they have evolved
from existing technologies such as distributed computing, web services, the
Internet, various cryptography technologies providing security features and
virtualization technology.
As we can see, none of these technologies is completely new.
They have existed for quite some time and have been serving
various needs.
