Abstract :
We develop an optimized program for the N-body problem on the CM-5 with vector units. The work is intended to make full use of the power of the vector pipelines provided by the CM-5 equipped with vector units to improve the computation performance. Some development issues using the vector units are discussed. The code is written in CDPEAC, an assembly-like language which can be called from C. Performance data and some analysis results are given
