Historically, scientific computing applications have been statically linked before running on massively parallel High Performance Computing (HPC) platforms. In recent years, demand for supporting dynamically linked applications at large scale has increased. When programs running at large scale dynamically load shared objects, they often request the same file from shared storage. These independent requests tax the shared storage and the network, causing a significant delay in computation time. In this paper, we propose to leverage a proven file sharing technique, BitTorrent, abstracted by an on-node FUSE interface to create a system-level distribution method for these files. We detail our proposed methodology, related work, and our current progress.

 

Bio: Matthew G. F. Dosanjh is a third year PhD student advised by Professor Patrick G. Bridges within the UNM Department of Computer Science. He received his bachelors degree in Computer Science from UNM in the spring of 2010. He decided to stay at UNM to pursue a PhD. His research interests center around high performance computing, particularly in scalability and resilience.
