Abstract

我々は,グリッド環境上に分散した汎用並列計算機群と専用並列計算機を結合し,各種物理現象の複合シミュレーションを可能とする計算環境HMCS-Gを設計し,重力専用計算機GRAPE-6クラスタを中心とする計算宇宙物理学用のシステムを実装した.アプリケーションプログラミングの簡便さとシステム全体のスループット向上のため,グリッドRPCとしてOmniRPCを用い,HMCS-Gの特性に合わせた効率的なシステムを実現した.各種ネットワーク環境における初期性能評価の結果,ある程度のネットワークバンド幅のもとで,HMCS-Gは実アプリケーションの現実的な実行に耐える性能を提供できることが確認された.また,HMCS-Gにより,貴重な専用計算リソースであるGRAPE-6のようなシステムを,世界規模で共有することが可能となる.We have developed a hybrid computing system named HMCS-G which combines general purpose parallel systems and a special purpose machine for gravity calculation on computational grid environment. The prototype is implemented with GRAPE-6 gravity engine and OmniRPC as Grid-RPC with high portability and throughput. Through the preliminary performance evaluation on several network conditions, it is confirmed that the function and capability of HMCS-G can support actual application for multiphysics simulation. With HMCS-G, the utilization ratio of special purpose machines such as GRAPE-6 is also greatly enhanced through access from all over the world.
