Research Abstract

In this research, we have developed the parallelization strategy and the speedup technique for the simulation code of the many-body quantum system. Especially, we propose the communication algorithm in consideration of the network architecture of the many-core machines and the property of the quantum system, and then, we demonstrated that the algorithm can realize the high performance communications. Moreover, we simulate the real quantum problems using our developing codes and discussed the property of the problem by using the simulation results.
