Migration of a Complete 3D Poisson Solver from Legacy Fortran to CUDA
Speakers:

- A*STAR Institute of High Performance Computing
Abstract:
We describe our journey of migrating a legacy direct solver library for Poisson equations written in Fortran77 to CUDA in order to harness the computational power provided by the Tesla device ("Fermi"). This legacy library is still widely used today as it is the most complete library that can deal with three different boundary conditions (Dirchlet, Neumann and Cyclic) and two grid configurations (staggered and centered) independently in any of the three dimensions (x, y, z); giving a total of over 200 configurations.
