This paper discusses implementation of a parallel numerical algorithm for simulating multiphase flow in porous media, with application to reservoir simulations. The flow is described by a system of two coupled nonlinear PDEs which is discretized by the finite difference scheme and linearized by the Newton's method. Different implementations on the latest KSR-1 parallel computers are discussed to demonstrate the performance improvement by using different parallelization strategies; automatic parallelization, semi-automatic parallelization, and manual parallelization. Timing results show that good speedup can be achieved by using compiler directive on this type of architecture.
