Video: Antarctic Ice Sheet Simulations

In this video, the DOE SciDAC-funded BISICLES experiment investigates the millennial-scale vulnerability of the Antarctic Ice Sheet (AIS) due solely to the loss of its ice shelves. Starting at the present-day, the AIS evolves for 1000 years, exposing the floating ice shelves to an extreme thinning rate, which results in their complete collapse. The visualizations show the first 500 years of the simulation — after that point, the ice sheet continues to evolve and retreat, but less dramatically.

Cray Powers Haas Formula 1 Team

For the third year in a row, the American Haas F1 Team will use the computational capacity of a Cray Cray CS500 cluster supercomputer powered by AMD EPYC 7000 processors to handle its large CFD simulations for the 2019 season. “The double precision computing power of our new system will help solve our most demanding CFD and data challenges.”

Video: Altair Acquires SIMSOLID for Faster Product Simulation

Today Altair announced the acquisition of SIMSOLID, a company focused on full-fidelity CAD assemblies to provide fast, accurate, and robust structural simulation without requiring geometry simplification, cleanup, or meshing. “We believe SIMSOLID is a revolutionary technological breakthrough which will have a profound impact for product design,” said James Scapa, Altair’s Founder, Chairman, and CEO, “It’s incredibly fast, accurate, and robust and we believe a game changer for our industry.”

ExaFLOW Project takes on High-order CFD

After three years of working on key algorithmic challenges in CFD, the European ExaFLOW Project it touting a series of industry milestones. With three flagship runs, ExaFLOW has managed to work on different specific CFD use cases which highlight the importance of their outcomes for both industry and academia. “After three years of working on key algorithmic challenges in CFD, the European ExaFLOW Project it touting a series of industry milestones.

Video: Graphical User Interfaces for HPC

Mark Dawson gave this talk at the Supercomputing Wales Swansea Symposium 2018. “Supercomputing Wales is funded to provide university research teams access to powerful computing facilities to undertake high-profile science and innovation projects within the consortium universities. Software Engineers across Wales to develop algorithms and customized software that harnesses the power of the facilities. The aim of the investment is to capture more external research funding, increase scientific partnerships, create highly-skilled research jobs and support collaborations with industrial and other partners. This will provide a step change in supercomputing-enabled scientific research in Wales.”

New Paper Looks at Solidification of High-pressure Ice in newly discovered Ocean Worlds

A team of theorists from Lawrence Livermore National Laboratory (LLNL) has solved a long-standing puzzle in the nucleation of a high-pressure phase of ice known as ice VII, which is believed to exist near the core of “ocean world” planets recently detected outside of the solar system, and has recently been discovered to exist within the Earth’s mantle. “By dissecting the thermodynamics and kinetics of interfaces, there are entirely new classes of problems that can be studied and, ultimately, controlled. A holy grail is to design self-regulating dynamic systems and machines that can utilize far-from-equilibrium dissipative dynamics to perform complex tasks, as in biological systems — control of nucleation is a step on this path.”

Supercomputing to Feed the World

Sharan Kalwani writes that that supercomputers a critical tool for predicting severe weather that could threaten entire regions with famine. “Models have been improved – although at too slow a pace for the general public at large – that now this HPC approach is taking root in more than just the monsoon predictions. Tropical storms are also important and cyclones are also quite rampant. Recently two Petaflop-capable machines have been installed in a special tropical weather department in the central part of the country.”

How HPC can Benefit Society

Sharan Kalwani writes that that one of the main reasons he got into computing long ago was the potential that he saw in using powerful news supercomputing tools towards addressing the needs of the society we live in. “The point here is that technically the challenges are very tractable, however society needs to also grow at a comparable, if not higher pace than the technology (which is evolving faster than us).”

Cloud and Enterprise Adopting HPC-proven CPU-based Interactive, Photorealistic Rendering

The TACC Frontera supercomputer, which will become the fastest academic supercomputer in the United States when it becomes operational in 2019, will rely on CPUs for visualization. “The ability to run and visualize anywhere with SDVis solutions, regardless of the scale of the visualization task and without requiring specialized hardware for interactive response, is the reason HPC centers no longer need to procure GPUs for visualization clusters.”

Using Ai to Automatically Diagnose Alzheimer’s Disease

Researchers from Stanford University have developed a deep learning based system that can automatically detect Alzheimer’s disease and its biomarkers from MRIs, with 94 percent accuracy. “Our method uses minimal preprocessing of MRIs (imposing minimum preprocessing artifacts) and utilizes a simple data augmentation strategy of downsampled MR images for training purposes,” the researchers stated in their paper.
