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.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
