We have developed a high level library, the Nearest Neighbor Tool (NNT), to facilitate the coding of finite difference approximation weather prediction models on parallel computers. NNT provides portability and ease of programming and at the same time optimizes performance by allowing the overlap of computation and communication to tolerate the latency of(More)
NOAA Forecast Systems Laboratory (FSL) is a technology evaluation and transition laboratory. In this role, FSL is evaluating massively parallel processors (MPPs) for operational use in real-time numerical weather prediction (NWP). To this end, FSL has developed a portability library known as the Nearest Neighbor Tool (NNT) to facilitate its evaluation. NOAA(More)
