Abstract :
Due to its high performance, optical fiber is more and more popular in the field of high performance computing. In this field, Message-Passing Interface (MPI) has been the most popular standard for parallel applications. MPICH2 is the most famous implementation of MPI. Optical fiber is a circuit-switched network, which needs to reserve an independent path before communication. Although the huge bandwidth of optical network can make up for this drawback, its influences on collective communication with high path building cost. In this paper, we present our experience in implementing MPICH2 over optical fiber with an agent supporting the control plane in optical fiber network; meanwhile wepsilave optimized the broadcast communication according to characteristics of the Optical network.
