Speaker(s) Title: 

Parallel File Systems today are comprised of multiple software components combined to provide concurrent and efficient access across hundreds or possibly thousands of storage devices. Using traditional programming models to develop these systems leads to large code bases, full of code that is difficult to follow, debug, and build on. In this presentation, I will describe a programming model based on concurrent state machines that has been useful in the implementation of the Parallel Virtual File System (PVFS), enabling concise specification of logical control flow. I will also describe a new approach that attempts to address a number of the lessons learned in PVFS.
