概要

A Three dimensional dense plasma particle code "SCOPE (Strongly COupled Plasma particIE code) " has been parallelized for both Intel Paragon XP/S (scalar-distributed memory) and NEC SX-4 (vector-shared memory) . Since a PPPM (Particle-Particle Particle-Mesh) method is used in the code, parallelization has been achieved by distributing PP Iatice zones into processing elements (PE) . A macro task method is introduced for the sheared memory machine (SX-4) with few modifications of the original code, while the nx library supported by Intel is used with considerable changes of the code necessory for the distributed memory machine (Paragon) . Scalarble speed up has been obtained up to 512 PE of Paragon and 32 CPU of SX. Performance of the parallelized codes is also evaluated.
