“…In other words, the code developed for general purpose CPUs is able to run on MIC only by recompiling. In our previous paper [16], we tested the performance of a classical PDES simulator ROSS on CPU and MIC respectively. The results showed that the multi-thread version ROSS performs much better than MPI based ROSS on MIC.…”

Abstract. The widespread of many-core processors brings new opportunities to enhance performance of PDES applications. MIC is a relative new many-core architecture compared with the widely-used GPU. In our previous paper, experiments for evaluating performance of a PDES simulator ROSS are designed and tested on MIC and CPU respectively. However, no related works have been done on evaluation PDES simulators on CPU+MIC collaborative platform. We observe that the MPI based ROSS performs poorly, while the multi-thread ROSS is not able to work on CPU+MIC platform. We propose a PDES simulator based on a MPI+OpenMP hybrid parallel modeled ROSS which can be called as ROSS-OMPI. We use MPI to handle the interactive events between CPU and MIC, while several OpenMP threads are issued to process events in parallel inside CPU and MIC respectively. The experiment results show that the hybrid model of ROSS brings better performance.
