Abstract
Increasingly, le systems for multiprocessors are designed with parallel access to multiple disks, to keep I/O from becoming a serious bottleneck for parallel applications. Although le system software can transparently provide high-performance access to parallel disks, a new le system interface is needed to facilitate parallel access to a le from a parallel application. We describe the di culties faced when using the conventional (Unix-like) interface in parallel applications, and then outline ways to extend the conventional interface to provide convenient access to the le for parallel programs, while retaining the traditional interface for programs that have no need for explicitly parallel le access. Our interface includes a single naming scheme, a multiopen operation, local and global le pointers, mapped le pointers, logical records, multi les, and logical coercion for backward compatibility. 1
