Abstract
The calculation performance of three types of moment calculation algorithms is evaluated on SX super computer. Those are WorkArray, LISTVEC compile directive, and RETRY algorithms. The used simulation model consists of two dimensional in space. The calculation time of WorkArray and RETRY methods show almost same cost. That of LISTVEC methods is about 1.5 times larger than those of others. The used main memory size of RETRY and LISTVEC methods is almost same cost. That of WorkArray is a few times larger than those of others. The algorithm of WorkArray and LISTVEC are simple but that of RETRY is complicated. However, in the view points of total merits, we recommend to use RETRY algorithm.
