摘要: Today's massively parallel machines are typically message-passing systems consisting of hundreds or thousands processors. Implementing applications efficiently in this environment is a challenging task, and poor design decisions can be expensive to correct. Tools techniques that allow the fast accurate evaluation different parallelization strategies would significantly improve productivity application developers increase throughput on architectures. This paper investigates one major issues building tools compare strategies: determining what type performance models code computer system sufficient for comparison strategies. The built around case study employing Performance Prediction Tool (PerPreT) predict Parallel Spectral Transform Shallow Water Model (PSTSWM) Intel Paragon.
