On a Mission of Disaster Management & Scientific Discoveries
Wednesday Mar 24, 2021
Wednesday Mar 24, 2021
We explore the critical role of visualization and visual analytics in disaster management and medical research with Paul Navrátil, Director of Visualization at the Texas Advanced Computing Center (TACC), and Jim Jeffers, Sr. Principal Engineer and Sr. Director of Advanced Rendering and Visualization at Intel. Paul reveals TACC’s approach to recent weather crises, as well as their partnership with National Oceanic and Atmospheric Administration (NOAA) in hurricane forecasting. He also talks about their collaboration with the Open Science community in the national HPC mobilization effort to fight COVID-19. Jim unpacks the complexities of in-situ analysis, ray tracing and line-of-sight physics. And they jam about the SOLAR Ray Tracing Consortium, Khronos Group ANARI Working Group and more.

Porting GROMACS Across Heterogeneous Architectures
Monday Mar 08, 2021
Monday Mar 08, 2021
In this second episode about GROMACS, one of the world’s most widely used open source molecular dynamics (MD) applications, we explore the quest to simplify portable, performant programming with Erik Lindahl, Biophysics Professor at Stockholm University & KTH Royal Institute of Technology, and Roland Schulz, Parallel Software Engineer at Intel. Andrey Alekseenko, Postdoctoral Fellow at KTH Royal Institute of Technology and SciLifeLab, shares his experiences porting GROMACS across hardware architectures. And our guests talk about Khronos SYCL’s rapid growth and vibrant, thriving community.

Expanding the SYCL 2020 Ecosystem with hipSYCL and DPC++
Tuesday Jan 26, 2021
Tuesday Jan 26, 2021
Open standards underpin the future of heterogeneous programming, and as Intel Principal Engineer Jeff Hammond points out, SYCL has proven in many ways that “standards don’t cost you a thing and you get portability.” A modern C++ language, SYCL has demonstrated amazing growth and now boasts four implementations—ComputeCpp, triSYCL, hipSYCL and DPC++. hipSYCL Creator Aksel Alpay explains some of the differences between these implementations, and how hipSYCL is evolving to incorporate DPC++ features contributed to the SYCL 2020 specification, including unified shared memory (USM), reductions, group algorithms and subgroups. The two also dive into a discussion of buffers and accessors, and Aksel debunks a few myths around hipSYCL.

Igniting the Next Generation of Deep Learning
Wednesday Jan 06, 2021
Wednesday Jan 06, 2021
Increased processing power, massive amounts of data, and the development of more advanced algorithms have brought deep learning to the forefront, and TensorFlow has emerged as one of the world’s most popular machine learning frameworks. Penporn Koanantakool, Google Senior Software Engineer, and Ramesh, Intel Principal Engineer, share how their teams are collaborating to optimize TensorFlow for the latest Intel technologies using oneAPI Deep Neural Network Library (oneDNN). The result: remarkable performance gains that will benefit applications spanning natural language processing, image and object recognition, autonomous vehicles, fraud detection, medical diagnosis and treatment, and much more. Intel-optimized TensorFlow is now made available through Intel AI Analytics Toolkit and is being used within Google Cloud Platform and a Google Health project.

A Proving Ground for Open Standards
Tuesday Dec 08, 2020
Tuesday Dec 08, 2020
Andrew Lumsdaine, Chief Scientist at Northwest Institute for Advanced Computing, shares his journey in parallelism, from the HPC community’s early skepticism of and eventual move to C++ to build large systems, to his pursuit to develop a series of C++ libraries to strike at the contradiction between abstraction and performance, to today’s reality that parallelism and heterogeneity are essential for achieving performance. Together, Andrew and Mike Voss, Principal Engineer at Intel, underscore the value of open standards and high-quality implementations of open standards—specifically, the oneAPI specification and Intel oneAPI toolkits, respectively—and provide listeners with ways to get involved in helping shape ISO C++, Khronos SYCL, DPC++ and oneAPI.

Who better to have a spicy discussion with about #OpenMP than Tim Mattson and Bronis de Supinski? These two have truly lived at the forefront of the amazing, decades-long OpenMP journey, from its inception to its preeminence as a foundational tool for HPC application programmers. Listen to what’s coming in 5.1 and beyond, how the C++ ecosystem is evolving, why Python in HPC, and have fun as these two razz each other.
