Abstract
The message passing interface (MPI) is used to implement the proposed parallel multigrid method, which ensures the portability of the code. The object-based programming model adopted for this work is also described. The performance of the parallel algorithm is studied using two sets of benchmark problems: fixed-size problems and scaled-size problems. In order to demonstrate portability, three widely used parallel systems; an IBM SP2, an SGI Origin2000 and a CRAY T3E are employed. The obtained results shows that the proposed parallel algorithm is highly scalable and can efficiently solve large scale problems on a large number of processors.
