On efficiency improvement of grid applications
Sirod Sirisup*, Suriya U-ruekolan
ABSTRACT: Grid computing technology addresses the growing need for computing resources in simulation-based engineering and science (SBES). However, optimal performance of grid computing technology requires `virtually tightly coupled' computing resources. This, though, may not be economically available in many research societies. In this work, we propose a new approach to improve performance of a typical parallel application for SBES on a `virtually not tightly coupled' grid computing environment. To this end, we have proposed, implemented, and investigated the performance of a new grid programming technique based on the Global Arrays toolkit and multi-level topology-aware approach. We have found that performance of the evaluating application implemented with this new technique outperforms both MPICH-G2 and native Global Arrays implementations, but is still comparable to that of the application implemented with OpenMP, the native Symmetric-Multi Processors programming.
