An efficient three-dimensional unstructured Euler solver has been parallelized on a Cray Y-MP C90 shared memory computer and on an Intel Touchstone Delta distributed memory computer. Both machines yield comparable performance rates. However, the availability of sophisticated software tools enabled the parallelization of EUL3D on the shared memory vector/parallel CRAY Y-MP C90 with minimal user input. On the other hand, the implementation on the distributed memory massively parallel architecture of the Intel Touchstone Delta machine is considerably more involved. As massively parallel software tools become more mature, the task of developing or porting software to such machines should diminish. It has also been shown that with today's supercomputers, and with efficient codes such as EUL3D, the aerodynamic characteristics of complex vehicles can be computed in a matter of minutes, making design use feasible
