The Globus Alliance is a community of organizations and individuals developing fundamental technologies behind the “Grid,” which lets people share computing power, databases, instruments, and other on-line tools securely across corporate, institutional, and geographic boundaries without sacrificing local autonomy. The Globus Toolkit is an open source software toolkit used for building Grid systems and applications. It is being developed by the Globus Alliance and many others all over the world. A growing number of projects and companies are using the Globus Toolkit to unlock the potential of grids for their cause.

Abstract
Quantum structure or scattering calculations often belong to a class of computational problems involving the aggregation of a set of matrices representing a linear problem to be solved. The authors discuss a number of approaches based on cluster and grid computing, and discuss the implementations and the respective merits and shortcomings. The authors consider MPI-based cluster computing in a self-scheduling paradigm, CoBRA (a cpu-harvesting desktop grid) in a farmer-worker paradigm, and a batch-computing paradigm on BEGrid (the Belgian research grid facility). It is observed that for all paradigms an efficient implementation is possible, yielding results within a comparable time frame.
