Note (General): The Numerical Simulator system (NS system), installed in the National Aerospace Laboratory (NAL) in February 1987, is composed of FACOM VP400, VP200, and M780 computers. The first two are vector-processor-type supercomputers and the last is a scalar computer. To extract full performance from supercomputers, it is necessary to give consideration to solution algorithms, programs and data structure, program coding, etc. to match individual supercomputers. NAL has various application software programed for a scalar computer. They are not necessarily matched for the VP400 and VP200, therefore we tuned them up to facilitate high speed processing on those supercomputers. This paper reports the relative performance of the VP400, VP200 and M780, by comparing computing time of the original and the tuned programs on each computer. Also, methods of effective FORTRAN programming to increase vectorization rate and high speed computation with FORTRAN programs on the machines are described.
