An Incremental Approach to Porting Complex Scientific Applications to GPU/CUDA

João GazollaJavier DelgadoEsteban CluaS. Masoud Sadjadi

This paper proposes and describes a developed methodology to port complex scientific applications originally written in FORTRAN to the nVidia CUDA. The process was developed and validated by porting an existing FORTRAN weather forecasting algorithm to a GPU parallel paradigm. We believe that the proposed porting methodology described can be successfully utilized in several other existing scientific applications.
