Keynote: HPC Storage: Adapting to Change
Phil Carns (Argonne National Laboratory)
Abstract: Exascale computing has arrived, bringing with it a remarkable, and still growing, collection of data-intensive application use cases. This is an exciting opportunity for I/O researchers and practitioners, but it also increases pressure for us to keep pace and deliver on the promise of HPC technology. The community cannot afford to rest on its accomplishments; expanding access to new systems, problem domains, and user communities calls for us to adapt to new technologies, data management needs, and end-user expectations. This presentation will highlight illustrative examples in the field and discuss strategies for adapting to changes in HPC storage.
About the speaker: Phil Carns is a computer scientist in the Mathematics and Computer Science Division of Argonne National Laboratory. He is also an adjunct associate professor of electrical and computer engineering at Clemson University and a fellow of the Northwestern-Argonne Institute for Science and Engineering. He received his Ph.D. in computer engineering from Clemson University in 2005.
Phil has worked at Argonne since 2008, acting as technical lead, principal investigator, and developer for influential HPC research projects including Darshan (application I/O characterization), TOKIO (platform I/O characterization), Mochi (composable data services), PVFS (parallel file system), CODES (storage system simulation), and the Exascale Computing Project (data libraries and services for exascale platforms). Phil is a recipient of multiple R&D 100 awards. His research interests include HPC storage architectures, HPC system software, and I/O workload analysis.
