Event Description: With increasing demand for AI in HPC, there has been an explosion in architectures, programming models, and AI frameworks. The already-daunting task of programming for heterogenous systems has become even more challenging. This BoF, organized by the IXPUG but not limited to Intel technology, will focus on portable programming across a wide variety of architectures running a diverse set of HPC, and AI workloads. This BoF will explore challenges, state-of-the-art approaches, and emergent best practices for programming across heterogeneous systems and novel architectures, identifying common principles and practices that enable development and maintenance of software across sites, architectures, and applications.

Panelists:
- Dr. Alastair Murray, Codeplay
- Alastair Murray is the VP of Product Engineering at Codeplay Software Ltd. In this role he oversees various compiler and SYCL orientated projects, working to broaden hardware support across the SYCL ecosystem through both backend target support and extensions to open standards. He is also co-chair of the Hardware Abstraction Special Interest Group in the newly formed UXL Foundation and the oneAPI Community Forum before it; and he is involved in OpenCL where he is a co-editor of the specification and was heavily involved in writing the 3.0 version. Prior to joining Codeplay he did his PhD in compiler design at the University of Edinburgh, and was a post-doctoral researcher at Virginia Tech’s System Software Research Group working on heterogeneous compilers and operating systems.
- Dr. Venkatatram Vishwanath, Argonne National Laboratory
- Venkatram Vishwanath is a computer scientist at Argonne National Laboratory. He is the Data Science Team Lead at the Argonne Leadership Computing Facility (ALCF). His current focus is on algorithms, system software, and workflows to facilitate data-centric applications on supercomputing systems. His interests include scientific applications, supercomputing architectures, parallel algorithms and runtimes, scalable analytics and collaborative workspaces. He has received best papers awards at venues including HPDC and LDAV, and a Gordon Bell finalist. Vishwanath received his Ph.D. in computer science from the University of Illinois at Chicago in 2009.
- Dr. Zhao Zhang, Rutgers University
- Dr. Zhao Zhang is an assistant professor in the Department of Electrical and Computer Engineering at the Rutgers University. Prior to that, Dr. Zhang was a computer scientist and led the machine learning group at Texas Advanced Computing Center (TACC). From 2014 to 2016, Dr. Zhang was a postdoc researcher at AMPLab, UC Berkeley and the data science fellow in Berkeley Institute for Data Science. Dr. Zhang received his Ph.D. from the Department of Computer Science at UChicago in 2014. Dr. Zhang has extensive experience in high performance computing (HPC) and big data systems. His recent research focus is the fusion of HPC and deep learning (DL) with a wide range of topics of optimization algorithm, I/O, architecture, and domain applications.
- Dr. Anna Pietarila Graham, Los Alamos National Laboratory
- Dr. Anna Pietarila Graham is the deputy group leader for HPC-ENV and the LANL Center of Excellence (CoE) Lead for Crossroads and El Capitan at the Los Alamos National Laboratory. Prior to LANL, she worked as a staff scientist in observational and computational solar physics at the Max Planck Institute for Solar System Research in Germany and the National Solar Observatory in Tucson, AZ, and as a research geophysicist focusing on depth imaging at Shearwater GeoServices in Houston, TX. Anna received her MSc in physics from Lund University, Sweden, and her Ph.D. in astrophysics from the University of Oslo, Norway.
