Note (General): We investigated parallel processing using multitasking on the CRAY X-MP/216 system, which is a supercomputer with multiple vector processors. Multitasking is a multiprocessor computer operation mode that executes two or more parts of a single program in parallel. It is one method of high-speed processing. The FORTRAN programs under investigation are those for a subsonic flow over an airfoil, an unsteady transonic flow over a wing, and an inviscid compressible flow through a two-dimensional cascade. These programs were rewritten so that they could be effectively executed on two CPUs. The computing times of the original programs with one CPU, multitasked programs with one CPU, and multitasked programs with two CPUs are presented in this paper, and the ratio of the computing times of the multitasked programs to those of the original program is discussed.
