Porting large applications to distributed computing platforms
is a challenging task from a software engineering perspective.
The Computational Grid has gained tremendous popularity as
it aggregates unprecedented amounts of compute and storage
resources by means of increasingly high performance network
technology. The primary aim of this paper is to demonstrate
how the development time to port very large applications to this
environment can be significantly reduced. TOP-C and AMPIC
are software packages that have each seen successful
application in their respective domains of parallel computing
and process creation/communication. We combine them to
implement and deploy a master-worker model of parallel
computing over the Computational Grid. To demonstrate the
benefit of our approach, we ported the 1,000,000 line Geant4
sequential code in three man-weeks by using our TOP-C/AMPIC
integration. This paper evaluates the benefits of our approach
from a software engineering perspective, and presents
experimental results obtained with the new implementation of
Geant4 on a Grid testbed.
