| Abstract(in English) | When the large-scale parallel computing system that uses a lot of computing nodes aims at performance improvement, interconnection network that realizes communication among computing nodes is one of the key factor which affects the performance of whole system. Therefore performance evaluation of interconnection network is necessary, but the evaluation environment of network that built using actual equipment is unreal in terms of cost. Thus we think that performance simulation by software is one of the effective way. When the behavior of large-scale interconnection network is simulated by simulator, the problem is that the quantity of process is enormous and performance evaluation requires a lot of time. In this paper, we tried to reduce the simulation time by parallelization using GPU. Since the change to simple parallelization don't elicit the enough performance of GPU, we aim at acceleration of simulation speed by tuning for GPU. For example it is the improvement of efficiency of memory access. The result of performance evaluation, the parallelized simulator achieved the speed up ratio of maximum 37.8 times. |
