Communicating efficiently on cluster based grids with MPICH-VMI
Emerging infrastructure of computational grids composed of Clusters-of-Clusters (CoC) interlinked through high throughput channels promises unprecedented raw compute power for terascale applications. Projects such as the NSF Teragrid and EU Datagrid deploy CoCs across multiple geographical sites providing tens of teraflops. Efficient scaling of terascale applications on these grids poses a challenge due to the heterogeneous nature of the resources (Operating Systems and SANs) present at each site that makes interoperability among multiple clusters difficult. In addition, due to the enormous disparity in latency and throughput of the channels within the SAN and those interlinking multiple clusters, these CoC grids contain deep communication hierarchies that prohibit efficient scaling of tightlycoupled applications. In this paper, we present a design of a grid-enabled MPI called MPICH-VMI for running terascale applications over CoC based computational grids. MPICH-VMI is based on MPICH
