In a gas turbine engine, the pressure expansion through the high- and low-pressure turbines (LPT) is achieved in a number of subsequent stages. The interaction of multiple stages of rotors and stators is a crucial source of deterministic unsteadiness which has repercussions on the loss production mechanisms, and it is thus of great importance to […]

Implementation of high-performance GPU kernels in Nektar++ Due to the recent evolution of high performance computing hardware from single-core central processing units (CPUs) to multi-core CPUs and the emergence of general purpose graphics processing units (GPGPUs or short GPUs), these shared memory systems are now characterised by a high degree of parallelism. They also possess […]

Date: Wed, 30 September 2020, 14:00 – 16:00 Summary: Beyond CFD: In this workshop we wish to share experiences on application of PDE solvers which go beyond CFD tools, for example composable solvers, stability analysis, inverse problems, data assimilation and uncertainty quantification. The format of the on-line workshop will involve a series of 3 short […]

Research Software Engineering and PRISM  Photo by Glenn Carstens-Peters on Unsplash  The PRISM platform is characterised by its group of advanced scientific research software and the teams that build and maintain this software. Software engineering expertise is therefore a significant part of PRISM. The term Research Software Engineering or RSE is becoming increasingly common within the research community. Indeed, the […]

We are delighted to announce that Prof Piggotty, PRISM Co-I, has been successful in being awarded the following EPSRC grants: EPSRC Impact Acceleration award “Multi-scale adjoint-enabled modelling to improve operational storm surge forecasting at the Flood Forecasting Centre (FFC) and support the wider modelling community” funded for 12 months to work on translational impact activities […]

An EPSRC Impact Acceleration grant was awarded to Co-I Colin Cotter to fund a research associate (Dr Jack Betteridge) for six months from October 1 2019 to March 30 2020 to accelerate the impact of EPSRC-funded research (through the Mathematics of Planet Earth Centre for Doctoral Training) on hybridisable implicit solvers for atmospheric dynamical cores […]

PRISM workshop on best practices for software training and workshops: Exploring online teaching in a post-pandemic era! Date: 21st May 2020 Location: on-line Summary: In this workshop we wish to share experiences and best practices on the use of workshops and tutorials for the PRISM related software. In light of the currently changes due to […]

Introduction Nektar++ is a sophisticated computational fluid dynamics codebase developed for multiple operating systems with an involved set of build dependencies. Current development relies on a Continuous Integration and Delivery (CI/CD) pipeline based on a Buildbot farm with test environments provided by virtual machines using on-premises compute infrastructure as execution hosts. Code hosting is provided […]

In modern computer architectures, the gap between processor clock speed and memory bandwidth is constantly increasing, meaning that to attain optimal performance, algorithms with a high degree of arithmetic intensity – i.e the ratio between computations performed and the amount of data transferred from the memory (DRAM) – are required. In this context, high-order finite […]

In this project we are  enabling ‘coupling’ in the Firedrake stack, for the purpose of simulation, optimisation and uncertainty quantification. We are particularly interested in the type of coupling in which two or more domains of possibly distinct physical natures interact with each other via interfaces. One characteristic example of such coupling is ‘ocean-atmosphere coupling’ […]
