PDRA or RA in Task-based Programming

The role

Applications are invited for a Postdoctoral Research Associate or Research Associate in the Scientific Computing research group. The successful candidate is expected to work within a team of colleagues who are all contributing towards the core software developed by our ExCALIBUR projects.

In the task project, we have built a system which can track existing and hypothetical task parallelism within source code: Developers annotate their application with instructions “this could be a task” before they run their application. Our software then displays the existing and hypothetical task graph and delivers recommendations how the annotations could be translated into various task-based programming languages. As a new colleague, you will:

• Either build a new simulator which takes the task graph plus an abstract machine model – which we have to specify – and then delivers predictions and recommendations how fast the code might run if we introduced tasking;
• Or uses the task tool to inject (more) tasking into an existing smoothed particle hydrodynamics code which simulates galaxy formation.

In the multigrid project, we develop a toolkit for matrix-free multigrid solvers fitting to higher-order discretisation in space and time with dynamic AMR and local time stepping. As a new colleague, you will either:

• Develop new multigrid ingredients;
• Or apply our multigrid ideas to the application domain of interest (computational astrophysics)

This role is available at Grade 6 as a Research Associate or at Grade 7 as a Postdoctoral Research Associate.

This post is fixed term for 12 months, due to funding restrictions, and can be extended subject to a successful grant extension.
