内容記述 | In this paper, we first show the performance evaluation results on a large clustered SMP system consisting of the Fujitsu PRIMEPOWER HPC2500 installed to JAXA with 56 SMP compute nodes with 32 CPUs each for typical hybrid parallel CFD codes, and discuss the correlation between the code features and the parallel scalable performance. Next, we propose a sustained performance prediction method for the hybrid parallel programming by making the extension of Amdahl's law, and show the validity of the performance prediction by comparing the scalability performance data of the JAXA CFD codes and the prediction data from the proposed extended Amdahl's law. We found that the extended Amdahl's law is useful for the performances prediction for the JAXA CFD codes with less communication, and that the enhanced version of extended Amdahl's law with inter-node communication effects included is valid for the communication intensive codes. | |||||
