| Abstract | The performance of a pseudo spectral turbulence simulation code on various supercomputers, with either shared memory or distributed memory, is presented. The communication with the memory is intense, and careful consideration of the two memory configurations is needed to obtain high performance. The investigations of the performance show that the scaling with the number of processors is excellent for both memory systems. Also, vector processors are compared with super scalar processors, and the performance is generally higher for the vector processor since the code vectorizes well. However, the computers with the scalar processors, and distributed memory, have a much larger number of processors which gives an overall better performance for the total machine. The numerical code, with e.g. 24 ยท 10 degrees of freedom, was run at 3.5 Gflop/s on 64 processors on an IBM SP2 machine. |
