The Search for Gravitational Waves

In this video from PASC18, Alexander Nitz from the Max Planck Institute for Gravitational Physics in Germany presents: The Search for Gravitational Waves. “The LIGO and Virgo detectors have completed a prolific observation run. We are now observing gravitational waves from both the mergers of binary black holes and neutron stars. We’ll discuss how these discoveries were made and look into what the near future of searching for gravitational waves from compact binary mergers will look like.”

ISC Keynote: Tackling Tomorrow’s Computing Challenges Today at CERN

In this keynote video from ISC 2018, Physicist and CTO of CERN openlab discusses the demands of capturing, storing, and processing the large volumes of data generated by the LHC experiments. “CERN openlab is a unique public-private partnership between The European Organization for Nuclear Research (CERN) and some of the world`s leading ICT companies. It plays a leading role in helping CERN address the computing and storage challenges related to the Large Hadron Collider’s (LHC) upgrade program.”

Low-Mach Simulation of Flow and Heat Transfer in an Internal Combustion Engine

In this video from PASC18, Saumil Patel from Argonne describes his poster on engine combustion simulation. “This work marks a milestone achievement in using Nek5000, a highly-scalable computational fluid dynamics (CFD) solver, to capture turbulent flow and thermal fields inside realistic engine geometries. In the context of an arbitrary Lagrangian-Eulerian (ALE) framework, several algorithms have been developed and integrated into Nek5000 in order overcome the computational challenges associated with moving boundaries (i.e. valves and pistons).”

AMD steps up to HPC Workloads at ISC 2018

In this video from ISC 2018, Derek Bouius from AMD describes how HPC users can take advantage of new AMD EPYC processors and Radeon GPUs to accelerate their applications. “With the introduction of new EPYC processor based servers with Radeon Instinct GPU accelerators, combined with our ROCm open software platform, AMD is ushering in a new era of heterogeneous compute for HPC and Deep Learning.”

Bringing Big Compute to FEA

In this special guest feature, Gemma Church from Scientific Computing World discusses advances to FEA software as it is now used to simulate a wide range of physical phenomena. “With 40 years” experience in developing FEA technologies, the most significant challenges are not in the internal technical work. In fact, the major challenge might be termed institutional inertia. Many companies are hardwired with the thought that product design requires extensive physical prototyping.”

Finalists Vie for Coveted 2018 Altair Enlighten Award

Today Altair announced the finalists for the 2018 Altair Enlighten Award, which recognizes technology-focused organizations throughout the automotive industry driving innovation in vehicle lightweighting. “Every year brings more submissions and increasingly clever ways of removing weight from our vehicles. Observing the submissions grow in quantity and quality over the years is very encouraging because it demonstrates the commitment by the automotive companies and their suppliers to decrease the mass of our vehicles leading to a cleaner future for all of us.”

Atomicus Chart Software Brings Easy Analytics to Scientists

ISV vendor Atomicus is approaching the release of an advanced software component AtomicusChart developed for scientists researching physical, chemical, biological phenomena and for those who need a convenient tool to present the results in scientific formats. “The ATOMICUS CHART is a product from Atomicus, which can be re-used and integrated in any software requiring high-speed graphics for large volumes of data (including big data) and dedicated to the needs of analytical applications.”

From Weather Dwarfs to Kilometre-Scale Earth System Simulations

Nils P. Wedi from ECMWF gave this talk at PASC18. “The increasingly large amounts of data being produced b weather and climate simulations and earth system observations is sometimes characterised as a deluge. This deluge of data is both a challenge and an opportunity. The main opportunities are to make use of this wealth of data to 1) improve knowledge by extracting additional knowledge from the data and 2) to improve the quality of the models themselves by analysing the accuracy, or lack thereof, of the resultant simulation data.”

PASC18 Conference Grows in Attendance and Scope

Over at CSCS, Simone Ulmer writes that more than 400 scientists from all over the world met in Basel in early July for PASC18. With more than 200 talks centered around the conference theme of “Fast and Big Data, Fast and Big Computation” 400 attendees enjoyed the exchange of knowledge in the area of Scientific Computing and Computational Science.

Podcast: Supercomputing New Enzymes for Breaking Down Plastics

In this TACC podcast, Gregg Beckham from NREL and Lee Woodcock from the University of South Florida describe how they are using supercomputers to engineer an enzyme that breaks down plastic. “We used computer simulations to understand how a polymeric ligand like PET would be able to bind to the enzyme,” said study co-author Gregg Beckham, a Senior Research Fellow and Group Leader at the US National Renewable Energy Laboratory (NREL). “We also conducted experimental work to show that indeed, the PETase can break down water or soda bottles, industrially relevant PET films, and another plastic, polyethylene furanoate.”
