Panel method computational performance on CM-2 and iPSC/860 MPP machines H. Hu, M. Soe Department of Mathematics, Hampton University, Hampton, Virginia 23668, USA ABSTRACT A comparative study of computational performance of CM-2, iPSC/860 and Cray-YMP computers for calculating matrix coefficients (aerody- namic influence coefficients) using a two-dimensional source panel method (boundary elements) code has been made. Detailed performance results are obtained for CM-2 and iPSC/860 with different numbers of proces- sors / nodes and for Cray-YMP with a single processor. The comparison of the performance indicates that the aerodynamic influence coefficient calculations on CM-2 and iPSC/860 with a large number of processors / nodes near- or outperforme the equivalent Cray-YMP code and achieve a high performance. Since the aerodynamic influence coefficient calcultaions take over 80% of the total computational time on Cray-YMP when the problem is large enough, it is very i
