Real-World Applications in Numerical Ocean Modeling

Fangli Qiao from the First Institute of Oceanography in China gave this talk at PASC19. “In this interdisciplinary dialogue we will address such questions as – what is state-of-the-art in numerical ocean modeling? And what are the current trends in model improvement? We will consider several applications of the surface wave-tide-circulation coupled numerical ocean model, such as nuclear radiation spread prediction following damage to the Fukushima Nuclear Power in 2011, and the rescue of lives at sea after boats capsized near Phuket in 2018.”

Large-Scale Optimization Strategies for Typical HPC Workloads

Liu Yu from Inspur gave this talk at PASC19. “Ensuring performance of applications running on large-scale clusters is one of the primary focuses in HPC research. In this talk, we will show our strategies on performance analysis and optimization for applications in different fields of research using large-scale HPC clusters.”

The Challenges of Updating Scientific Codes for New HPC Architectures

In this video from PASC19 in Zurich, Benedikt Riedel from the University of Wisconsin describes the challenges researchers face when it comes to updating their scientific codes for new HPC architectures. After that he describes his work on the IceCube Neutrino Observatory.

Flexibly Scalable High Performance Architectures with Embedded Photonics

Keren Bergman from Columbia University gave this talk at PASC19. “Data movement, dominated by energy costs and limited ‘chip-escape’ bandwidth densities, is a key physical layer roadblock to these systems’ scalability. Integrated silicon photonics with deeply embedded optical connectivity is on the cusp of enabling revolutionary data movement and extreme performance capabilities.”

Video: Dr. Michela Taufer sets the stage for SC19 with ‘HPC is Now’

In this video, Dr. Michela Taufer from the University of Tennessee recaps PASC19 and looks ahead to SC19. “SC is still a place to share new and futuristic ideas, but our plenary sessions, panels, papers and conversations, aren’t just about the future anymore. They’re about what’s happening in the world of HPC today. Because … HPC is Now. That’s the theme of SC19 in Denver next November, and I believe it perfectly captures the state of this exciting field.”

Video: HPC for Instabilities in Aerospace Propulsion Systems

Thierry Poinsot from Toulouse Fluid Mechanics Institute gave this talk at PASC19. “This talk focuses on aerospace propulsion where optimization often leads to the occurrence of instabilities where combustion couples with acoustics, leading to unacceptable oscillations (the most famous example is the Apollo engine which required 1330 full scale tests to reach acceptable oscillation levels). The talk will show how simulation is used to control these problems, in real gas turbine engines and in rocket engines.”

Panel Discussion: Exascale and Beyond – Challenges in Productive and Sustainable Software

In this video from PASC 2019, Lois Curfman McInnes from Argonne and Rich Brueckner from insideHPC moderate a panel discussion on the challenges of software development for exascale supercomputers. “Software—the key crosscutting technology by which teams collaborate toward predictive science—is dramatically increasing in complexity due to disruptive architectural changes, multiphysics and multiscale modeling, the coupling of simulations and data analytics, and the demand for greater reproducibility and sustainability.”

Video: Jack Wells from ORNL on his new role as VP of OpenACC.org

Today OpenACC.org announced a newly elected vice president reflecting increased user influence within the organization. Additionally, the organization announced its 2019 Annual Meeting will be hosted by RIKEN Center for Computational Science (RIKEN R-CCS) in Japan, as well as the schedule of upcoming hackathons and bootcamps around the world.

Video: Portable Programming Models Highlighted at PASC19

In this video from PASC19 in Zurich, Technical Papers co-chair Sunita Chandrasekaran provides some highlights from the conference. After that, Sunita previews the upcoming Workshop on Performance Portable Programming Models for Accelerators (P3MA) at ISC 2019. “This workshop will provide a forum to bring together researchers and developers to discuss community’s proposals and solutions to performance.”

Video: Simulating Planet-Wide Bioenergy and Human Health on the Summit Supercomputer

In this video from PASC19 in Zurich, Dan Jacobson from ORNL describes how researchers are using the #1 Summit supercomputer to tackle the challenges facing an ever-growing human population. These planet-wide simulations could not even have been attempted before the advent of pre-exascale systems like Summit.”We are using CoMet to investigate the genetic architectures underlying complex traits in applications from bioenergy to human clinical genomics.”
