The framework is designed for parallel computations on distributed and shared memory computers, thus allowing for efficient solution of large-scale problems. The framework provides automated data exchange between processors based on stencil information. This automated data exchange allows a user to add FD schemes without knowledge about underlying parallel infrastructure. The framework includes acoustic solver based on staggered second-order in time and various orders in space FD schemes with perfectly matched layer and/or free surface boundary conditions.59 ppengTechnical reportTR09-07
