Leveraging Heterogeneity Aurora as a Critical Step
Increasingly, HPC application developers are turning to heterogeneous computing to continue to achieve the super exponential growth that has fueled the Top500 supercomputers over the last three decades. Further, HPC now encompasses workflows spanning classical HPC or modeling and simulation, AI, and Big Data and Analytics. Aurora, the exascale machine to be delivered to Argonne in 2022, embraces all three pillars, and is a critical step on the path toward leveraging heterogeneous computing. It has been called out by the DOE as needing to meet real application benchmarks in each of modeling and simulation, AI, and data analytics. Aurora will achieve these capabilities by leveraging heterogeneity in a CPU - GPU co-designed system

In this talk I will describe important trends in HPC, describe Aurora, both the novel hardware and the innovative software capabilities that will be available in production. I will provide examples of how we are striving to achieve a tighter integration across each of the three key exascale pillars mentioned above. I will also present our vision for the future of HPC including how we are designing for the trends of increasing heterogeneity, and a much broader set of workflows including AI, cloud, and edge. I will show that Aurora represents an important step in that direction and share a vision of how we will address the challenges raised by those trends in future generations.

Dr. Robert W. Wisniewski is an ACM Distinguished Scientist, IEEE Senior Member, the CTO and Chief Architect for High Performance Computing and a Senior Principal Engineer at Intel Corporation. He is the technical lead and PI for Aurora, the supercomputer to be delivered to Argonne National Laboratory that will achieve greater than an exaflop of computation. He is also the lead architect for Intel's cohesive and comprehensive software stack that was used to seed OpenHPC, and serves on the OpenHPC governance board as chairman. He has published over 79 papers in the area of high performance computing, computer systems, and system performance, filed over 59 patents with 46 issued, with an h-index of 40 with over 6500 citations, and given over 69 external invited presentations. Before coming to 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 was the most powerful computer in the world in June 2012, and occupied 4 of the top 10 positions on Top 500 list.
