Developing a Future-Proof CFD Code
| Description | In this award we explored whether is it possible to develop new scientific software in such a way that the software would run quickly and efficiently on a diverse range of new supercomputers. This wasn't possible previously, with specialised versions of software being optimised for each type of supercomputer. The current approach is very time consuming, expensive, and error prone. We have now demonstrated that it is possible to develop scientific software which is "performance portable" across a wide variety of very diverse supercomputer architectures, such as GPUs from Nvidia or AMD, or CPUs from Intel or ARM. |
| Exploitation Route | Others could use similar techniques to those developed by us to create their own performance portable software applications. For example, anyone using CFD-like techniques should be able to exploit our findings, delivering much higher fidelity CFD simulations, or much quicker simulations at the same resolution than before. They will also be able to exploit GPUs using our new techniques. |

| Description | Demonstrated that performance portable applications are possible, and so caused Intel to parter with us and fund a new parallel computing centre in Bristol. This has also led to recent collaborations with Rolls-Royce and a new EPSRC Prosperity Partnership proposal submission in February 2018, with academic partners including a different group at Oxford, Cambridge, Edinburgh (EPCC) and Warwick. |

| Title | ROTORSIM |
| Description | ROTORSIM is a structured grid, multiblock, compressible finite-volume computational fluid dynamics (CFD) code developed by Prof. Christian Allen, head of the Bristol Aerodynamics research group. This award has contributed a new design for the code to make it highly performance portable, and uses OpenCL so that it can exploit modern GPUs and Intel Xeon Phi to achieve much higher performance on next generation supercomputers. |
| Type Of Technology | Software |
| Year Produced | 2016 |
| Impact | ROTORSIM is also being used as one of the new benchmarks in the FP7 Mont Blanc European Exascale research project, making it one of the first applications to run at large scale on an ARM-based supercomputer. ROTORSIM is one of the few applications to run at extremely large scale on the Titan supercomputer at Oak Ridge national laboratory in the USA. ROTORSIM also helped form the basis of the first phase of the Intel Parallel Computing Center at the University of Bristol. |
