✦ Synopsis

Two different numerical solutions of the two-component kinetic collection equation were implemented on parallel computers. The parallelization approach included domain decomposition and MPI commands for communications. Four different parallel codes were tested. A dynamic decomposition based on an occupancy function provided the optimum balance between time performance and flexibility for any number of processors. The occupancy function was defined according to the number of calculations required at each grid point in the domain. Speed-up performance depended very much on the parallel code used and in some cases very good results were obtained for up to 32 processors.

The multi-moments method of S. Tzivion, G. Feingold, and Z.

For solving this set of equations an accurate and efficient method is proposed. The method conserv

Techniques for solving linear equations on a single instruction multiple data (SIMD) computer such as the ICL DAP have so far been confined to simple methods such as the Successive Overrelaxation and Alternating Direction Implicit algorithms. While these techniques are adequate for simple finite dif
