Abstract :
The unprecedented scale, heterogeneity and varied usage patterns of computational grids pose significant technical challenges to any underlying file system that supports them. While grids present a host of new concerns for file access, we focus on two issues: performance and usability. We discuss the Legion I/O model and interface to address the latter area. We compare the Legion and Globus I/O models against a baseline to validate the efficiency of existent grid-based file access solutions
