LCG stands for “Large Hadron Collider Computing Grid”, and its mission is to build and maintain data storage and analysis infrastructure for the entire high energy physics community that will use CERN’s large hadron collider. It contributed significantly to the development of computing grids, particularly in Europe.

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.
