Research team from Imperial College London shortlisted for ACM Gordon Bell Prize and SC16 Best Paper Award

A research team from Imperial College London has been shortlisted for the 2016 ACM Gordon Bell Prize for High Performance Computing Applications and also for SC16’s Best Paper Award.

Led by Dr. Peter Vincent, Reader in Aeronautics and EPSRC Early Career Fellow, the submission ‘Towards Green Aviation with Python at Petascale’ (Peter Vincent, Freddie Witherden, Brian Vermeire, Jin Seok Park, and Arvind Iyer, all of Imperial College London) covers the topic of achieving accurate simulation of unsteady turbulent flow, which is critical for improved design of ‘greener’ aircraft that are quieter and more fuel-efficient, demonstrated by application of PyFR, a Python based computational fluid dynamics solver, to petascale simulation of such flow problems.

The rationale behind algorithmic choices, which offer increased levels of accuracy and enable sustained computation at up to 58 percent of peak DP-FLOP/s on unstructured grids, are discussed in the context of modern hardware. Presenting a range of software innovations, results are presented from a full-scale simulation of flow over a low-pressure turbine blade cascade, along with weak/strong scaling statistics from the Piz Daint and Titan supercomputers, and performance data demonstrating sustained computation at up to 13.7 DP-PFLOP/s.

Developing novel numerical methods and applying them to solve challenging fluid flow problems across science, engineering, and medicine, Vincent and his team focus on developing academic advances that have real and significant impact within, such as the open-source flow solver PyFR. 

With an interest in theoretical aspects of high-order numerical methods for unstructured grids, and their implementation on modern hardware platforms, Imperial College London are partners in the Innovate UK and EPSRC funded Hyperflux project which has developed high order CFD solver prototype, based on next generation High-Order Flux Reconstruction (HO/FR) CFD methods. Exploiting the power of HPC, the software is up to 30x more cost effective than standard 2nd order finite volume CFD methods. High-order CFD methods using the flux reconstruction (FR) approach offer new potential for the accurate, efficient simulation of unsteady flows (including acoustics) with shed vortices and wakes, providing higher fidelity solutions than currently achievable with low-order schemes on unstructured grids. 

Results for the ACM Gordon Bell Award and SC16 Best Paper Award will be announced at the SC event, taking place 13th-18th November. 

About Hyperflux

Hyperflux is one of several funded projects within the ‘Towards Zero Prototyping’ Programme, run by Innovate UK and the EPSRC. CFMS is leading the integration and dissemination activities, working with Imperial College London, experts in High-Order Methods (HOMs) and cloud high performance computing and computational fluid dynamics specialist, Zenotech. Current CFD technology is lacking in accuracy and efficiency for unsteady flow problems (including acoustics) and for resolving shed vortices and wakes. HOMs provide a potential solution, enabling higher fidelity solutions than currently achievable with low-order schemes on unstructured grids. Dr. Peter Vincent and his group at Imperial College are experts in this field, working with CFMS and Zenotech to create a high-order CFD solver prototype, which is now available at CFMS for industrial and research evaluation. Shown to be up to 30x more cost effective than standard 2nd order finite volume CFD methods, CFMS is offering organisations the opportunity to evaluate the working capability, with access to test cases across aerospace, automotive, maritime, civil and renewables engineering.

 About CFMS

The Centre for Modelling & Simulation (CFMS) is proud to be a growing, independent and not-for-profit organisation that specialises in high value design capability. We promote advanced modelling and simulation, underpinned by HPC, pushing the boundaries of technology.

Through our exceptional, collaborative, virtual and physical facility, we enable the adoption and acceleration of new technologies for advanced modelling and simulation, while improving learning and developing awareness of state-of-the-art. Engaging with organisations large and small, we help to provide access to the right tools, resources, skills and technologies, resulting in increased productivity and faster, more informed decision-making.

As a trusted and neutral provider, our vision is to drive a practical revolution in engineering capability and design, working with organisations to reduce risk in the design phase, product development costs and time to market.
