| Abstract : | The unprecedented scale, heterogeneity, and varied usage patterns of grids pose significant technical challenges to any underlying file system that will support 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 Legion and Globus I/O against a baseline to validate the efficiency of existent grid-based file access solutions., |
