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.”

Future MareNostrum 5 Supercomputer at BSC to host Made-in-Europe Technologies

Today the Barcelona Supercomputing Center announced plans to host EuroHPC processor technologies within its future Mare Norstrom 5 supercomputer. “Offering an heterogenous architecture, probably based on two big clusters with different characteristics, is BSC’s proposal to optimize both response times and energy use of the different works that the future supercomputer will have to compute. The details of this heterogenous architecture will be defined as the works of definition and the infrastructure tender progress.”

RDMA, Scalable MPI-3 RMA, and Next-Generation Post-RDMA Interconnects

Torsten Hoefler from ETH Zurich gave this talk at the Swiss HPC Conference. “Network cards contain rather powerful processors optimized for data movement and limiting the functionality to remote direct memory access seems unnecessarily constraining. We develop sPIN, a portable programming model to offload simple packet processing functions to the network card.”

Video: Supercomputing Dynamic Earthquake Ruptures

Researchers are using XSEDE supercomputers to model multi-fault earthquakes in the Brawley fault zone, which links the San Andreas and Imperial faults in Southern California. Their work could predict the behavior of earthquakes that could potentially affect millions of people’s lives and property. “Basically, we generate a virtual world where we create different types of earthquakes. That helps us understand how earthquakes in the real world are happening.”

AMD Verifies Vega20 GPU in Record Time on Azure

AMD engineers executed a physical verification pass of the Radeon Instinct Vega20 – its largest 7nm chip design – in ~10 hours on Microsoft Azure. The job used the TSMC-certified Calibre nmDRC software platform from Mentor, running on the Microsoft Azure cloud platform using HB-series virtual machines, powered by AMD EPYC processors.

Storage Advances for HPC and AI

In this special guest feature from Scientific Computing World, Robert Roe looks at storage technologies being developed to suit both AI and HPC workloads. “While AI may steal the headlines, HPC is still generating advances in storage technology. Cloud environments have made significant progress over the last five to ten years, going from what was seen as fringe or niche technology to a much more ubiquitous platform, particularly with the advances made by cloud giants such as Google and Amazon.”

Video: The Kokkos C++ Performance Portability EcoSystem for Exascale

Christian Trott from Sandia gave this talk at the GPU Technology Conference. “The Kokkos C++ Performance Portability EcoSystem is a production-level solution for writing modern C++ applications in a hardware-agnostic way. We’ll provide success stories for Kokkos adoption in large production applications on the leading supercomputing platforms in the U.S. We’ll focus particularly on early results from two of the world’s most powerful supercomputers, Summit and Sierra, both powered by NVIDIA Tesla V100 GPUs.”

Video: Perlmutter – A 2020 Pre-Exascale GPU-accelerated System for NERSC

Nick Wright from Lawrence Berkeley Lab gave this talk at the GPU Technology Conference. “We’ll present an overview of the upcoming NERSC9 system architecture, throughput model, and application readiness efforts. Perlmutter, a Cray system based on the Shasta architecture, will be a heterogeneous system comprising both CPU-only and GPU-accelerated nodes, with a performance of more than 3 times Cori, NERSC’s current platform.”

The Pending Age of Exascale

In this special guest feature from Scientific Computing World, Robert Roe looks at advances in exascale computing and the impact of AI on HPC development. “There is a lot of co-development, AI and HPC are not mutually exclusive. They both need high-speed interconnects and very fast storage. It just so happens that AI functions better on GPUs. HPC has GPUs in abundance, so they mix very well.”

HPE to Acquire Cray for $1.3 Billion

Today HPE announced that the company has entered into a definitive agreement to acquire Cray for approximately $1.3 billion. “This pending deal will bring together HPE, the global HPC market leader, and Cray, whose Shasta architecture is under contract to power America’s two fastest supercomputers in 2021,” said Steve Conway from Hyperion Research. “The Cray addition will boost HPE’s ability to pursue high-end procurements and will speed the combined company’s development of next-generation technologies that will benefit HPC and AI-machine learning customers at all price points.”
