Implementation and Evaluation of MPI Library with Globus Toolkit for Establishing λ Computing Environment

We propose a new architecture, the lambda computing environment, that accomplishes high speed data transmission over optical fibers. In the lambda computing environment, we can achieve highly reliable high-speed communication by establishing wavelength paths. In this paper, we use the Globus toolkit to build a grid environment and establish the lambda computing environment using the AWG-STAR system. Moreover, we implement the MPI library using services of the Globus toolkit and the shared memory of the AWG-STAR system to exchange data, and evaluate performance of distributed computation in a lambda computing environment. Our results show that the performance depends on the number of accesses to the shared memory and the size of exchanged data
