Evaluation of a spectral element CFD code on parallel architectures

We present an evaluation of a Spectral Element Navier-Stokes solver on three generations of parallel architecture. The parallel platforms used are a network of Transputers, an Intel iPSC/860 and a Meiko CS2. While performance on the older Transputer and iPSC/860 machines is fairly predictable, the b...

Description
Summary:We present an evaluation of a Spectral Element Navier-Stokes solver on three generations of parallel architecture. The parallel platforms used are a network of Transputers, an Intel iPSC/860 and a Meiko CS2. While performance on the older Transputer and iPSC/860 machines is fairly predictable, the behaviour of the code on the SPARC-10 based Meiko CS2 demonstrated the influence of the internal memory hierachy on performance. These effects give the code problem dependent performance parameters that makes scaling properties difficult to quantify. Our code however, seems future proof, provided sufficiently large problems can be found to overcome the relatively large communications costs with respect to the processor speed.
