✦ Synopsis

Honjou, N., K. Ohtsuki, M. Sekiya and F. Sasaki, A parallelization technique for the speedup of configuration interaction computing, Parallel Computing 17 (1991) 297-310 In order to speed up configuration interaction (CI) computing by means of fork/join based parallel processing, we have considered a parallelization approach to high performance parallel processing, and adopted it to the energy expression computing of a practical CI program ATOMCI. It is proved from the performance evaluation on a tightly-coupled three-processor system that the parallel processing of CI computing is really effective, and our parallelization approach is appropriate to the speedup of Ci computing.

A parallel computing approach to run fast and full-wave electromagnetic simulation of complex structures in Grid Computing environment is presented. In this study, we show how Grid Computing improves speed and/or reliability over that provided by a single computer, while typically being much more co
