Postdoctoral Research Associate

The Role Applications are invited for a Postdoctoral Research Associate in Task-based SPH Formalisms and the Performance Prediction of Task Codes. The successful candidate is expected to make contributions to the two ExCALIBUR projects Task-based Parallelism and PAX-SPH led by Profs Tobias Weinzierl and Richard Bower.

The successful applicant will be expected to extract task execution codes from running supercomputing applications without a major performance penalty, and to investigate into algorithms and heuristics how these task graphs can be scheduled optimally. The candidate should study to which degree such a posteriori knowledge about optimal scheduling can be fed into state-of-the-art or upcoming runtimes (schedulers) and which heuristics are particularly releveant to the domain of SPH and/or particular application areas and benchmarks. The work has to built upon and feed back into existing supercomputing codes such as Otter (task tracing), SWIFT (SPH) and ExaHyPE (Eulerian simulation). In the ideal case, the candidates help both SWIFT and ExaHyPE to migrate their runtime to the latest OpenMP standard, while they also assess to which degree all concepts can be transferred into the SYCL/oneAPI paradigm.
