Petroleum Reservoir Simulator. Models underground flow and thermodynamics of hydrocarbons

Coding Styles (data decompositions, computational methods):

Fortran 90, HPF, MPI, Newton-Raphson iterative solvers, domain decomposition

Extrinsic Interfaces Used (and reasons):

None

Performance Information, if Available (including any possible comparisons to MPI and/or OpenMP):

MPI versions are 2x faster when the processor count exceeds 4-8 but is closer at lower
processor counts

Please comment on any aspects of the application that might be interesting, including any problems using HPF effectively:

Efficiency, vis-a-vis MPI, is an issue for larger processor counts Grid irregularity and load balancing are concerns (HPF 2.0?).
