Watch 5,000 Robots Merge to Map the Universe in 3-D

In this video, scientists describe how the Dark Energy Spectroscopic Instrument (DESI) will measure the effect of dark energy on the expansion of the universe. It will obtain optical spectra for tens of millions of galaxies and quasars, constructing a 3D map spanning the nearby universe to 11 billion light years. “How do you create the largest 3D map of the universe? It’s as easy as teaching 5,000 robots how to “dance.” DESI, the Dark Energy Spectroscopic Instrument, is an experiment that will target millions of distant galaxies by automatically swiveling fiber-optic positioners (the robots) to point at them and gather their light.”

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.

Video: Bill Dally Keynote on Accelerated Machine Learning from GTC Israel

In this video from GTC Israel, Bill Dally from NVIDIA gives a keynote talk on accelerated computing for Machine Learning and HPC. “GTC is the largest and most important event of the year for GPU developers. GTC and the global GTC event series offer valuable training and a showcase of the most vital work in the computing industry today – including artificial intelligence and deep learning, virtual reality, and self-driving cars.”

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.”

Video: MIT Makes Billion-Dollar Bet on Ai and Machine Learning

Today MIT announced a new $1 billion commitment to address the global opportunities and challenges presented by the prevalence of computing and the rise of artificial intelligence. The initiative marks the single largest investment in computing and AI by an American academic institution, and will help position the United States to lead the world in preparing for the rapid evolution of computing and AI. ” As we look to the future, we must utilize these important technologies to shape our world for the better and harness their power as a force for social good.”

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.”

Video: The March to Exascale

As the trend toward exascale HPC systems continues, the complexities of optimizing parallel applications running on them increase too. Potential performance limitations can occur at the application level which relies on the MPI. While small-scale HPC systems are more forgiving of tiny MPI latencies, large systems running at scale prove much more sensitive. Small inefficiencies can snowball into significant lag.

Video: Bridging the Automated Vehicle Gap: Consumer Trust, Technology and Liability

Kristin Kolodge from J.D. Power and Associates gave this talk at the HPC User Forum in Detroit. “With the rapid emergence of new technology in the automotive industry, understanding driver behavior and preferences within the vehicle is more crucial than ever for automakers. For 50 years, J.D. Power has been providing rich automotive consumer insights. Now, J.D. Power will work with HARMAN to go beyond measuring consumer insights to help automakers around the world better measure and understand how their evolving products are satisfying customer needs.”

Sunita Chandrasekaran Receives NSF Grant to Create Powerful Software Framework

Over at the University of Delaware, Julie Stewart writes that assistant professor Sunita Chandrasekaran has received an NSF grant to develop frameworks to adapt code for GPU supercomputers. She is working with complex patterns known as wavefronts, which are commonly found in scientific codes used in analyzing the flow of neutrons in a nuclear reactor, extracting patterns from biomedical data or predicting atmospheric patterns.

Video: Reflecting on the Goal and Baseline of Exascale Computing

Thomas Schulthess from CSCS gave this talk at the Blue Waters Summit. “Application performance is given much emphasis in discussions of exascale computing. A 50-fold increase in sustained performance over today’s applications running on multi-petaflops supercomputing platforms should be the expected target for exascale systems deployed early next decade. We will reflect on what this means in practice and how much these exascale systems will advance the state of the art.”
