HPC Connects: Mapping Global Ocean Currents

In this video from the SC17 HPC Connects series, Dimitris Menemenlis from NASA JPL/Caltech describes how supercomputing enables scientists to accurately map global ocean currents. The ocean is vast and there are still a lot of unknowns. We still can’t represent all the conditions and are pushing the boundaries of current supercomputer power,” said Menemenlis. “This is an exciting time to be an oceanographer who can use satellite observations and numerical simulations to push our understanding of ocean circulation forward.”

HPC I/O for Computational Scientists

Phil Carns from Argonne gave this talk at the 2017 Argonne Training Program on Extreme-Scale Computing. “Darshan is a scalable HPC I/O characterization tool. It captures an accurate but concise picture of application I/O behavior with minimum overhead. Darshan was originally developed on the IBM Blue Gene series of computers deployed at the Argonne Leadership Computing Facility, but it is portable across a wide variety of platforms include the Cray XE6, Cray XC30, and Linux clusters.  Darshan routinely instruments jobs using up to 786,432 compute cores on the Mira system at ALCF.”

Video: The AI Initiative at NIST

Michael Garris from NIST gave this talk at the HPC User Forum. “AI must be developed in a trustworthy manner to ensure reliability and safety. NIST cultivates trust in AI technology by developing and deploying standards, tests and metrics that make technology more secure, usable, interoperable and reliable, and by strengthening measurement science. This work is critically relevant to building the public trust of rapidly evolving AI technologies.”

Video: Supercomputing Models Enable Detection of a Cosmic Cataclysm

In this podcast, Peter Nugent from Berkeley Lab explains how scientists confirmed the first-ever measurement of the merger of two neutron stars and its explosive aftermath. “Simulations succeeded in modeling what would happen in an incredibly complex phenomenon like a neutron star merger. Without the models, we all probably all would have been mystified by exactly what we were seeing in the sky.”

Video: NASA Advanced Computing Environment for Science & Engineering

Rupak Biswas from NASA gave this talk at the Argonne Training Program on Extreme-Scale Computing. “High performance computing is now integral to NASA’s portfolio of missions to pioneer the future of space exploration, accelerate scientific discovery, and enable aeronautics research. Anchored by the Pleiades supercomputer at NASA Ames Research Center, the High End Computing Capability (HECC) Project provides a fully integrated environment to satisfy NASA’s diverse modeling, simulation, and analysis needs.”

John Gustafson to host BoF on Posit Arithmetic at SC17

John Gustafson from A*STAR will host a BoF on Posit arithmetic at SC17. Entitled, “Improving Numerical Computation with Practical Tools and Novel Computer Arithmetic,”  this BOF will be co-hosted by Mike Lam with discussions on tools for measuring floating point accuracy. “This approach obtains more accurate answers than floating-point arithmetic yet uses fewer bits in many cases, saving memory, bandwidth, energy, and power.”

How the POP Performance Optimization Centre at BSC is Speeding up HPC in Europe

In this video, Jesús Labarta from the Barcelona Supercomputing Center describes the POP (Performance Optimization and Productivity) Centre of Excellence led by BSC. According to Labarta, POP’s performance analysis results in performance improvements ranging from 10-15% to more than 10 times. Best of all, the POP services are free of charge to organizations / SMEs / ISVs / companies in the EU!

HPC Connects: How Supercomputers Are Unraveling the Mystery of the Human Brain

In this video from SC17, Katrin Amunts from Jülich highlights how the massive European-based Human Brain Project (HBP), comprising a veritable orchestra of scientists, collaborates to deliver the most exquisitely detailed human brain models ever created. “We have to create an ‘atlas’ (of the brain) that has a very large size in terms and bits and bytes,” Amunts said.

Introducing the European EXDCI initiative for HPC

“The European Extreme Data & Computing Initiative (EXDCI) objective is to support the development and implementation of a common strategy for the European HPC Ecosystem. One of the main goals of the meeting in Bologna was to set up a roadmap for future developments, and for other parties who would like to participate in HPC research.”

Exascale: The Movie

In this video from HPE, researchers describe how Exascale will advance science and improve the quality of life for all. “Why is the U.S. government throwing down this gauntlet? Many countries are engaged in what has been referred to as a race to exascale. But getting there isn’t just for national bragging rights. Getting to exascale means reaching a new frontier for humanity, and the opportunity to potentially solve humanity’s most pressing problems.”
