PPFS - Portable Parallel File System

Abstract

We have developed (and continue to enhance) a portable, parallel input/output library to explore the design space for scalable input/output systems. This approach permits a wide range of experimentation with modest human resources. These input/output libraries are invoked by user input/output calls and rely on the underlying system software for physical input/output, though the option exists to replace the physical system with a simulation substrate. Interposing the libraries between the application and the system software allows us to quickly experiment with a variety of data distribution and data management algorithms. For example, local read ahead and write behind policies can be implemented in the user-level library, as well as coordinated global prefetching policies coupled with distributed caching.
