Applications are invited for a two-year Research Fellow / Senior Research Fellow position on the EPSRC Prosperity Partnership for Advanced Simulation and Modelling of Virtual Systems (ASIMoV) project. ASIMoV is a consortium project with collaborators from Rolls-Royce plc., the Centre for Modelling & Simulation (CFMS), Zenotech Ltd, the Universities of Edinburgh, Oxford, Cambridge, Bristol and Warwick/Birmingham. The aim of this 5-year project is to lead the virtual certification of gas turbine engines and develop the next generation of engineering simulation and modelling techniques for Rolls-Royce engine design.

You will possess a PhD degree (or equivalent) in Computer Science or a closely related discipline and have a strong background in developing parallel applications for High Performance Computing systems and will be able to contribute to the design, analysis, implementation, optimization and deployment of parallel algorithms and software for multi-core and many-core architectures on large-scale cluster systems. You should have excellent programming skills in C/C++ or FORTRAN and have demonstrable experience in writing and running parallel codes using MPI, OpenMP, CUDA or SYCL/OpenCL. You will also have interest in the design and development of compilers/translators/code-generation, with good knowledge gained in this area at least at undergraduate level. The ideal candidate would have excellent software development skills in relation to developing parallel numerical simulation software for HPC systems. The role requires an enthusiastic and task/goal oriented individual who will be able to communicate effectively and aim to deliver the ASIMOV goals.

The Warwick research contributions to the ASIMOV project will be led by Dr. Gihan Mudalige (Warwick) and Prof. Stephen Jarvis (Birmingham). The challenges to be addressed in this project at Warwick will involve:

1. High-Level Abstractions for performance portability 2. Performance modelling and optimization of HPC applications 3. Lean Computing Optimizations – Communications avoiding algorithms

Candidates should provide with their application form, a CV, a list of publications (if applicable) and contact details of two referees. Informal enquiries to g.mudalige@warwick.ac.uk are welcome.

Start date for the post is expected to be July 2021, but this is subject to negotiation.

Job Description

JOB DESCRIPTION

To work in the High-Performance and Scientific Computing (HPSC) Group, specifically supporting the ASIMOV project. To contribute to the research climate within the department, and to conduct and publish high-quality research within the project.

DUTIES AND RESPONSIBLITIES

Research and scholarship

• Contribute to delivering the Warwick work packages of the ASIMOV project. The specific deliverables for this post will be:

(1) Re-engineering Rolls-Royce's gas-turbine engine numerical simulation suite to utilize high-level domain specific abstractions frameworks/ DSLs (e.g. OP2 - https: // op-dsl.github.io/). A key part of the work will consist of development/extension of novel code-generation and translator tool-chains (working with production compiler frameworks such as LLVM) for OP2 targeting Rolls-Royce's production CFD codes.

(2) Integrate the high-level domain specific abstractions / DSLs based CFD solvers to Rolls-Royce's production workflow. In particular, integrate with Rolls-Royce's production coupler framework optimizing to utilize the best performance on multi-core (CPU) and many-core (GPU) clusters.

(3) Support the maintenance of the re-engineered DSL-based CFD solvers in line with developments in the wider Rolls-Royce production CFD dev team.

• Benchmark and measure performance and scalability of research codes developed as part of this project on multi-core and many-core systems including large-scale clusters such as ARCHER2 and Cirrus.

• Publication of research papers arising from this work, particularly targeting top-tier (A/A) conferences and journals.

Research Software Development

• Management of open source (and proprietary) software development processes and repositories in collaboration with Dr. Mudalige and external academic and industrial collaborators.

• In-cooperation of best-practices in software engineering for open source (and proprietary) software developed as part of this project

• Update and maintain open source (and proprietary) software documentation, help develop training material for the high-level domain specific libraries and support of end-users (supporting bug fixes and providing guidance).

• Setup continuous integration (CI) systems for robust software development

Administration and Other Activities

• Engaging with the day-to-day activities of HPSC group including group seminars, team meetings and workshops. • Liaising with, and presenting to, external industrial partners on the results of this research. • Attend, and contribute to, project meetings at project partner sites in the UK. • Depending on experience, system administration/management of HPC hardware in the HPSC group. • In cooperation with other team members, and collaborators establish and maintain open source software websites, allowing publicity and access to results.

The duties and responsibilities outlined are not intended to be an exhaustive list but provide guidance on the main aspects of the job. The postholder will be required to be flexible in their duties.

Further Particulars

The Project:

The strategic vision of this Prosperity Partnership for Advanced Simulation and Modelling of Virtual Systems (ASiMoV) is to enable the research and development of the next generation of engineering simulation and modelling techniques. Our aim is to achieve the world's first high fidelity simulation of a complete gas-turbine engine during operation, simultaneously including the effects of thermo-mechanics, electromagnetics, and CFD. This level of simulation will require breakthroughs at all levels, including physical models, numerical solvers, algorithms, software infrastructure, and Exascale HPC hardware. Our partnership uniquely combines fundamental engineering and computational science research with two high tech SMEs and Rolls-Royce plc to address a challenge that is well beyond the capabilities of today's numerical solvers. Simulation and modelling, enabled by high performance computing, have transformed the way products are designed and engineered. The technology developed for the Trent XWB, the world's most efficient aero engine, could only have been achieved through simulation and modelling. However, next generation products will place demands on simulation that cannot be met by incremental changes to current techniques. The ACARE Flightpath 2050 goals demand fundamental changes to engine architectures and the 2015 Aerospace Technology Institute Propulsion Strategy identified "virtual certification" as a key technology needed in the 2025-30 timeframe. The journey to virtual certification is an incremental one requiring a thorough evidential database to convince the certification authorities that the analysis can be trusted. It will move forward on a number of fronts. One of those is the whole engine tests to certify operational performance and thrust.

Our driving ambition is to realise new simulation technology for the ultra- high resolution and extreme scale needed for meaningful virtual certification models. For Rolls-Royce, virtual certification will bring a major business transformation requiring unprecedented trust in simulation and fundamental changes to design processes and skills. Estimated cost savings for virtual certification are measured in the many £millions per engine programme; but we also estimate that each simulation will require a billion core hours. At this scale, savings from computational cost and performance optimisation will be £millions per design study. Hence the need for ASiMoV to push forward the boundaries of numerical modelling and simulation on the next generation of Exascale supercomputers.

The Post:

The post-holders will be a Senior Research Fellow working with Dr. Gihan Mudalige at the University of Warwick. The post-holders will be based in the Department of Computer Science, and will work closely with team members in the High Performance and Scientific Computing Group (HPSC) and other members of the ASIMOV project, including Rolls-Royce plc.

There is a high probability to extend the duration of the post beyond 24 months based on performance and project funding. This is a fantastic opportunity to develop and lead work directly targeting next generation Exascale-level HPC systems and applications.
