Abstract

With the increase of embedding dimension, the computing scale of the permutation entropy algorithm will grow exponentially. Consequently, it puts forward higher requirements for the timeliness of calculation. The Sunway TaihuLight supercomputer is a totally independently designed and developed Chinese supercomputer with a new many-core processor, the SW26010. To fully take advantages of computing and storage resources of heterogeneous many-core cluster, the phase space matrix is divided between the core groups base on MPI, and internal parallelism bases on OpenACC in the core groups. By these methods, the permutation entropy algorithm is successfully transplanted and accelerated. The experimental results on dam oscillation dataset show that the performance of the single-core group version is 7.18 times faster than that of the MPE version, and the speedup ratio can reach 85.6 when using 128 core groups.
