Abstract

Grid computing pr sents two major challenges for deploying large scal applications across wide area networksgathering volunteers PC and clusters/parallel computers ascomputational resources: security and fault tolerance.This paper presents a lightweight Grid solution for thedeployment of multi-parameters applications on a set ofclusters protected by firewalls. The system uses a hierarchical design based on Condor for managing each clusterlocally and XtremWeb for enabling resource sharing amongth clusters.We discuss the security and fault tolerance mechanisms used for this design and demonstrate the usefulness of the approach measuring the performances of amulti-parameters bio-chemistry application deployed ontwo sites: University of Wisconsin/Madison and Paris SouthUniversity.This experiment shows that we can efficiently and safelyharness the computational power of about 200 PC distributed on two geographic sites.
