Abstract
In order to take advantages of the large number of processors which the massively parallel computer systems usually have, a new 2D parallelisation of the code SIMSON is introduced in this report. The performance of the major subroutines is analysed in detail to identify the bottle-necks of the code. The overall performance of the new 2D version is promising. In addition, a performance model is proposed and it predicts the performance well for the benchmark cases.
