Abstract
Grid technology has been studied and developed by numerous researchers in recent years. Data in conventional grid environments are changed by using TCP/IP. However, as long as the architecture is based on packet switching, highly efficient computing is difficult to achieve. We thus propose a new architecture, the computing environment, where network switches and computing nodes are connected to one another with optical fibers, thereby offering high-performance computing by establishing an optical wavelength path between shared memories on computing nodes. We established the lambda computing environment using the AWG-STAR system, and designed a data-sharing structure for the OpenMP library, which is a parallel-computing programming language utilizing shared memory. Moreover, we evaluated its performance against existing parallel computing in a PC-cluster environment by executing OpenMP applications.
