Adrian Jackson, from EPCC (Edinburgh Parallel Computing Centre), will deliver this research seminar in to the Engineering Department on parallel computing applied to fluid dynamics.
The presentation will start by summarising the main strategies for parallelising large simulation codes, particularly in view of emerging multi- and many-core processor architecture.
The hybrid parallelisation of a state-of-the-art nonlinear frequency-domain harmonic balance turbulent Navier-Stokes solver for general unsteady aerodynamics and aeroelasticity will then be presented. The hybrid parallelisation is based on optimal concurrent use of shared and distributed memory parallel computing. The talk will highlight some important features of the recently optimised hybrid parallelisation, aimed at maximising the parallel efficiency (scalability).
The successful implementation of these features will be demonstrated by presenting and discussing an exhaustive set of numerical results.
Adrian Jackson is Technical Architect at EPCC, University of Edinburgh, where he has worked for the past 11 years. He has worked with a wide range of academic and industry partners to provide HPC expertise and effort. He has also developed and teaches a number of courses as part of EPCC's Masters Programme and for external organisations and academic parties.
Currently he manages a team of researchers that works closely with a range of scientists to provide HPC knowledge and support, including through the NAIS (Numerical Algorithms and Intelligent Software) and Nu-FuSE (the G8 funded Nuclear Fusion Simulation at Exascale) projects.
He received an MSc in High Performance Computing from EPCC in 2002, following the award of a first class Bachelors of Science in Computer Science from The University of Edinburgh.
