Benchmark calculations with an unstructured grid flow solver on a SIMD computer

An unstructured grid flow solver was implemented on a massively parallel computer, and benchmark computations were performed. The solver was a two-dimensional computational fluid dynamics (CFD) code that performs first-order, steady-state solutions of the Euler equations. The parallel computer employed was the Connection Machine made by Thinking Machines, Corp. The CFD code was programmed in *Lisp, the accuracy of the code was verified, and numerous optimizations were implemented. Several benchmark runs were then made to assess and understand the impact of the code modifications and to obtain meaningful performance comparisons with other advanced computers.
