内容記述 | The performance evaluation for the various parallel programming languages is done using NS3D (P3) code under the condition of the large scale and the large number of processors. After the scalar optimization of the NS3D code, the code is parallelized using the various parallel programming languages and the performance is evaluated. The calculation part for the NS3D code is obtained a good parallel performance using the various parallel programming languages and the hybrid version (MPI + OpenMP and XPFortran + OpenMP). However, the communication part of the NS3D code indicates that the performance of the XPFortran (+ OpenMP) version is better than that of the MPI (+ OpenMP) version. It is necessary to improve the performance of the MPI (+ OpenMP) version. The performance ratio between the sequential calculation and the XPFortran + OpenMP using 1,440 CPUs is about 845. | |||||
