“The Importance of Tight Coupling for Achieving the Next Generation of HPC“

Abstract

Since processing speed has discontinued its inexorable climb, achieving the next HPC generation expected perform acne increase has been challenging. Yet, the HPC community has continued on an exponential curve exponentially exceeding Moore’s law. In this talk, I will examine architectural directions we are exploring to help us continue achieving that superexponential. I will describe three directions. The first, is memory coupled compute – bringing memory and compute much closer together. A second direction is tightly coupling general purpose cores and accelerators. And the third is tightly coupling many nodes into a supernode. For each of these I will provide motivation describing why they are valuable and then share the architectural directions we are exploring.

Bio

Dr. Robert W. Wisniewski is a Senior Vice President, Chief Architect of HPC, and the Head of Samsung’s SAIT Systems Architecture Lab. He is an ACM Distinguished Scientist and IEEE Senior Member. The System Architecture Lab is innovating technology to overcome the memory and communication walls for HPC and AI applications. He has published over 80 papers in the area of high performance computing, computer systems, and system performance, has filed over 62 patents with over 46 issued, has an h-index of 42 with over 7500 citations, and has given over 85 external invited presentations. Prior to joining Samsung, he was an Intel Fellow and CTO and Chief Architect for High Performance Computing at Intel. He was the technical lead and PI for Aurora, the supercomputer delivered to Argonne National Laboratory as one of the world’s first exascale computers. He was also the lead architect for Intel’s cohesive and comprehensive software stack that was used to seed OpenHPC, and served on the OpenHPC Governance Board as chairman. Before Intel, he was the chief software architect for Blue Gene Research and manager of the Blue Gene and Exascale Research Software Team at the IBM T.J. Watson Research Facility, where he was an IBM Master Inventor and led the software effort on Blue Gene/Q, which received the National Medal of Technology and Innovation, was the most powerful computer in the world in June 2012, and occupied 4 of the top 10 positions on the Top 500 list.
