Performance study of 3D integral equation computations on massively parallel computer T.G. Logan & H. Hu Department of Mathematics, Hampton University, Hampton, Virginia 23668, USA ABSTRACT A comparative study of computational performance of CM-5 and Cray- YMP computers for a three-dimensional numerical source panel method calculation is made. A serial FORTRAN code is converted into a parallel CM-FORTRAN code. The performance results are obtained on CM-5 with 32, 64 and 128 nodes along with those on Cray-YMP with a single processor. The comparison of the performance indicates that the parallel CM-FORTRAN code out-performs the equivalent serial FORTRAN code, except for the post-aerodynamic calculations where the "parallel" code is not fully parallelized. INTRODUCTION In recent years, the processors of conventional vector supercomputers seem to be approaching the limit in computational speed inherent in their tech- nology. However, the need for
