Toward global and grid computing for large scale linear algebra problems

Platforms of global computing and grid computing have been developed in parallel without any link between them. However, they can be considered as complementary tools and it would be interesting to gather their resources. Moreover, we focus on linear algebra which has been seldom fitted to global computing. In particular, we aim the eigen-problem which is often used by the applications of industrial companies and laboratories. In this paper, we unify those two goals. We fit the algorithm of bisection on a platform of global computing, XtremWeb, and on a platform of RPC programming, OmniRPC. Those software are deployed on two different geographic sites at the engineer school of Poly tech 'Lille, France, and at the HPCS laboratory of Tsukuba, Japan. The combination of two different software and two geographic sites allows to do a wide range of tests and, then, to analyze them and compare all configurations
