Improving weather and climate forecasts

By | Energy and climate change | No Comments
Dr. Eike Mueller and Prof. Rob Scheichl of the Department of Mathematical Sciences at the University of Bath use the Emerald GPU-accelerated supercomputer to develop highly scalable iterative solvers for very large partial differential equations in numerical weather and climate prediction. Overview To improve the accuracy of numerical weather and climate prediction codes, the model resolution has to be continuously increased. At the same time the total run-time has to satisfy strict operational requirements: tomorrow’s forecast is not very useful if it takes a week to produce it! This requires the development of highly scalable numerical algorithms which can run...

High-order Computational Fluid Dynamics

By | Advanced materials, Innovation and infrastructure, News | No Comments
Application to Design of Next-Generation Unmanned Aerial Vehicles Computational simulation of fluid flow, often referred to as Computational Fluid Dynamics (CFD), plays an critical role in the aerodynamic design of numerous complex systems, including aircraft, F1 racing cars, and wind turbines. CFD technology allows engineers to understand complex flow patterns, and thus perform aerodynamic design, without ever flying an aircraft, or even starting up a wind tunnel. Dr. Peter Vincent, and his team of researchers in the department of Aeronautics at Imperial College London, have been using the Emerald GPU cluster to test the performance of new ‘high-order accurate’ CFD...

Working towards the Square Kilometre Array

By | News, Satellites and space | No Comments
The Many-cOre Technology Investigating Value, Application, deploymenT and Efficiency project or (MOTIVATE for short); is a pathfinder project with the aim of investigating the application of the latest many-core technologies, such as GPUs, to deliver energy and cost efficiencies in the area of radio astronomy High Performance Computing. Astrophysical radio sources such as Pulsars are excellent probes of extreme physical processes originating from compact sources within our Galaxy and beyond. Generating intermittent radio bursts of milliseconds in duration, as observed here on earth, the signals generated by Pulsars carry valuable information about the physical processes occurring at the source as well as in the intervening interstellar or intergalactic...

Modelling the coastal effects of a Tsunami

By | Energy and climate change, Innovation and infrastructure | No Comments
Dr Serge Guillas from UCL’s Department of Statistical Science is researching models for geophysics. ThroughUCL’s membership of the Science & Engineering South (SES) Consortium, he has worked with GPU specialists in Oxford to greatly improve the performance of a tsunami simulation code. The team used the SES GPU-accelerated supercomputer, Emerald, to achieve its results. Background High-performance computing is an integral part of research aimed at modelling real-life phenomena. Recent, major tsunamis in Indonesia and Japan have caused the insurance industry and civil authorities around the world to demand better models to assess tsunami risk. Dr Serge Guillas received proof-of-concept funding from...

World leaders in Performance Sports Engineering

By | Advanced materials, News | No Comments
The Wolfson Unit at the University of Southampton have been working with America’s Cup teams for over 30 years, using experimental testing in towing tanks and wind tunnels to define and improve the performance of the racing yachts. The America’s Cup, the world’s oldest international sporting trophy, was sailed in mono-hulls with traditional soft sails until 2010 but for the 2013 Americas Cup the yachts have been changed to catamarans with solid wing sails. The result is a four-fold increase in speed, and a shift in performance prediction requirements from straight line speed through the water to dynamic manoeuvres and...

How the “Swine” flu virus develops drug resistance

By | Bioscience and medicine, News | No Comments
A University of Bristol team used the Emerald GPU supercomputer to investigate how mutations of a key enzyme of H1N1 “Swine” flu lead to the development of resistance to current antiviral flu treatments. H1N1-2009 is a highly adaptive virus derived from different gene segments of swine, avian and human influenza. Within months of its appearance in early 2009, the H1N1-2009 strain caused the first flu pandemic of the 21st-century. The antiviral drugs zanamivir (Relenza) and oseltamivir (Tamiflu), which target the neuraminidase enzyme in influenza, successfully treated the infection but widespread use of these drugs led to a series of mutations in...
