摘要：
This paper presents an MPI-parallelized version of a matching algorithm for synthetic aperture radar (SAR) images. First the necessity for automated matching and the chosen algorithm are outlined briefly, and the algorithmic structure and the applied parallelization strategy are then presented and discussed. Performance results on a Gray T3D and a PowerChallenge from SGI are given, showing unexpected differences between these architectures. Performance analysis indicates a bottleneck in data I/O.
