By employing both one- and two-dimensional partitioning methods, the performance of the program on NAL vector parallel computer 'NWT' was analyzed, and vector tuning and parallel tuning was applied to it to be suitable for NWT. Then a performance model of the program to estimate the consuming time of the program was made. By comparing the estimation time derived from the model and the actual time consumed, applicability of the performance model was evaluated and a good agreement was obtained. This work was done in the collaboration between ONERA (Office National d'Etudes et de Recherches Aerospatiales) and NAL.

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