Abstract(in English) | To solve the inter-node bandwidth bottleneck in parallel computing systems, we propose a wavelength routing inter-node interconnect “Optical Hub”. The physical topology of Optical Hub is star, which leads to advantages in term of its bandwidth, size and energy consumption. The logical topology is full mesh, which leads to advantages in term of latency and reliability. We introduced multi-path routings, which are suitable for the full-mesh logical topology such as Optical Hub, by replacing conventional MPI functions with our custom ones. We simulated execution time of parallel computing benchmarks using parallel computing simulator SimGrid. As a result, we have confirmed that the parallel computing system with Optical Hub can achieve higher performance and lower energy consumption than conventional ones. |
