An unstructured 3D Euler solver is parallelized on a Thinking Machine Corporation Connection Machine 5, distributed mem ory computer with vecto rizing capability. In this paper, the SIMD strategy is employed through the use of the CM Fortran langu age a nd the CMSSL scientific library. The performanc e of the CMSSL mesh partitioner is evaluated and the overall efficiency of the parallel flow solver is discussed.

“…Previous experience with distributed memory machines has been less than satisfactory. Such implementations require considerable effort and have not been able to demonstrate superior performance for this class of problems [11,12]. The shared memory vector-parallel architecture of the CRAY-YMP-C90 has proved to be very effective for the current type of problems.…”

A three-dimensional unstructured mesh Reynolds averaged Navier-Stokes solver is described. Turbulence is simulated using a single field-equation model. Computational overheads are minimized through the use of a single edge-based data-structure, an efficient multigrid solution technique, and the use of multi-tasking on shared memory multi-processors. The accuracy and efficiency of the code are evaluated by computing two-dimensional flows in three-dimensions and comparing with results from a previously validated two-dimensional code which employs the same solution algorithm. The feasibility of computing three-dimensional turbulent flows on grids of several million points in less than two hours of wall clock time is demonstrated.

“…Finally, Section 4 reports and analyses the performance results obtained on several parallel systems. We note that other works in this direction can be found in, among others, Johan et al [6] and Morano and Mavriplis [7] for experiences on the Connection Machine CM-5, Mavriplis et al [8] for the parallelisation of a multigrid Euler solver on the Intel Touchstone Delta.…”
