Toyama International Conference Center), Toyama Japan, PetaFLOPS scale computers such as the next-generation supercomputer K, are being developed in the world. These supercomputers still don't have enough capability to conduct detailed numerical simulations for actual ows in aerospace elds. At the moment, much faster computer with ExaFLOPS capability has been studied. One of the big challenges to realize ExaFLOPS scal computers is to achieve high level power efficiency, which greatly changes existing hardware architectures. This change may dramatically degrade the performance of existing CFD programs. Therefore, a new programing model for CFD is necessary for such novel architectures. As a rst step of a discussion of the new programing model, a loop structure of CFD program is discussed in this paper, based on the architecture trend of ExaFLOPS scale computers., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0061958005, レポート番号: JAXA-SP-12-010}, pages = {25--30}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {エクサフロップス級計算機に向けたプログラミングモデルに関する一考察}, volume = {JAXA-SP-12-010}, year = {2013} }
