Our research is about exploring parallel multigrid methods to solve three dimensional Poisson equation on a cylindrical coordinate system which will be implemented in many/multicore processor environment. First, we try to investigate the iteration method that used as smoother. Our objective is to reduce as much as possible the serial part of the solver. While the other part of multigrid methods like in restriction and prolongation process is easier to parallelize, in many-core architectures, memory access pattern is not too friendly to straightforward implementation. Next, we also investigate the parallelization in multinode systems, where some node might idle while the other nodes still do some computation. In order to achieve that, we try to consider some key issues: (1) thread parallelism that related to scalability with core count, (2) data-parallelism exposure to explore vectorization capabilities and (3) data-locality aware techniques.
