- Abstract
- In this paper present a parallel implementation, based on ScaLAPACK, of a direct 4SID method. As the computational stages of the method are solved mainly by direct calls to ScaLAPACK routines, we concentrate on the specific difficulties of the implementation, e.g. the redistribution of data between some stages. A structured matrix multiplication is implemented efficiently by a dedicated algorithm. We report experimental results that show good behavior for up to 16 processors.
