Abstract:

Concerns about energy efficiency and cost are forcing the US Exascale Computing Project to reexamine system architectures, and, specifically, the memory and storage hierarchy.

While memory and storage technologies have remained relatively stable for nearly two decades, new architectural features, such as deep memory hierarchies, non-volatile memory (NVM), and near-memory processing, have emerged as possible solutions.

However, these architectural changes will have a major impact on HPC software systems and applications. To be effective, software and applications will need to be redesigned to exploit these new capabilities.

In this talk, I will sample these emerging memory technologies, discuss their architectural and software implications, and describe several new approaches to programming these systems. One such system is Papyrus (Parallel Aggregate Persistent -yru- Storage); it is a programming system that aggregates NVM from across the HPC system for use as application data structures, such as vectors and key-value stores, while providing performance portability across emerging NVM hierarchies.
 

Speaker bio:

Dr Jeffrey Vetter is a Distinguished R&D Staff Member at Oak Ridge National Laboratory (ORNL). At ORNL, Dr Vetter is the founding group leader of the Future Technologies Group in the Computer Science and Mathematics Division, and the founding director of the Experimental Computing Laboratory (ExCL). He also holds a joint appointment at the University of Tennessee-Knoxville.

He earned his Ph.D. in Computer Science from the Georgia Institute of Technology.

He is a Fellow of the IEEE, and a Distinguished Scientist Member of the ACM. In 2010, Dr Vetter, as part of an interdisciplinary team from Georgia Tech, NYU, and ORNL, was awarded the ACM Gordon Bell Prize.

In 2015, he served as the SC15 Technical Program Chair.

His recent books, entitled Contemporary High Performance Computing: From Petascale toward Exascale (Vols. 1 and 2), survey the international landscape of HPC.
