Self organizing inter-grids virtual organization

Abstract

National audienceThe pervasive grid environment aim at combining the great computing capabilitiesof grid with the mobility capabilities of pervasive systems. The concept of pervasive grid impliesthe multiplication of users, and consequently of applications and needs. Thus, this mergingmake the integration of several heterogeneous platforms critical, especially in a context oftemporary and dynamic collaborations. Our approach consists, instead of homogenizing themiddlewares, in allowing several of them to interact into heterogeneous and dynamic virtualorganization (VO), called inter grid VO. This article focuses on the data management in thiskind of VO, and more precisely on monitoring information, which are both critical to the managementof the plateforms, and highly frequently updated. Our proposal is a an autonomousand self-organized virtual network architecture able to quiclky desseminate data while limitingthe network consumption. The efficiency of our approach as been proved on the experimentalplatform Grid 5000
