Distributed File Systems for Exascale Computing

SESSION: Doctoral Showcase - Early Research Showcase

EVENT TYPE: Doctoral Showcase

TIME: 3:30PM - 5:00PM

SESSION CHAIR: Wojtek James Goscinski

Presenter(s):Dongfang Zhao


It is predicted that exascale supercomputers will be emerging by 2019. The current storage architecture of High Performance Computing (HPC) would unlikely work well due to the high degree of concurrency at exascales. By dispersing the storage throughout the compute infrastructure, storage resources (also processing capabilities and network bandwidth) will increase linearly with larger scales. We believe the co-location of storage and compute resources is critical to the impending exascale systems. This work aims to develop both theoretical and practical aspects of building an efficient and scalable distributed file system for HPC systems that will scale to millions of nodes and billions of concurrent I/O requests. A prototype has been developed and deployed on a 64-node cluster, and tested with micro benchmarks. We plan to deploy it on various supercomputers, such as the IBM Bluegene/P and Cray XT6, and run benchmarks and real scientific applications at petascales and beyond.
