Legacy application software is typically written in a dialect of Fortran, and must be reprogrammed to run on today's microprocessor-based multicomputer architectures. We describe our experiences in modernizing a legacy direct numerical simulation (DNS) code with the KeLP software infrastructure. The resultant code runs on the IBM SP2 with higher numerical resolutions than possible with the lega...
