About the position

The EC-funded Center of Excellence for Exascale CFD (CEEC), https://ceec-coe.eu/, which started on January 1st 2023 and runs for four years, specializes in the area of numerical simulations for turbulence. Anyone who has ever flown knows that there can be turbulence, air currents that spin and twist with varying strength and direction. Today there are methods to calculate this seemingly unpredictable phenomenon, but they are complex and require a lot of computing power. Exascale computing offers such supercomputer performance. The main task of the advertised position is to contribute to the algorithmic development and enhancement of the consortium CFD applications. The work involves analysis of the consortium CFD applications using computer arithmetic tools, identifying possibilities for precision cropping, implementing provided algorithmic solutions, and benchmarking/ testing.  The opportunities for precision cropping can be evaluated using the Verificarlo framework (https://github.com/verificarlo/verificarlo) through stochastic and lower-precision emulation. This  will be done in collaboration with Li-PaRAD, UVSQ, Université Paris-Saclay which is one of the main institutions contributing to Verificarlo. 

To meet these needs, we are now looking for a project assistant for a temporary position.

The main responsibilities of the announced position are to:

• Characterize the numerical behavior and pinpoint abnormalities on the consortium CFD codes. 
• Deploy and improve the Verificarlo tool so it can be used in the CEEC context which targets heterogenous HPC platforms. 
• Evaluate the numerical behavior and energy-footprint of different algorithmic solutions into the consortium codes in close collaboration with and help from the codes’ developers.
• Evaluate the optimization impact on energy reduction and for sustainable development. In particular, find the best compromise in terms of accuracy and energy for different CFD kernels.

By working with CEEC, an project assistant will have an opportunity to:

• Collaborate with leading European researchers from five different countries and contribute to the algorithmic development driven by production-ready project applications.
• Access to HPC infrastructures including local and EU tier-0 supercomputers.
• Publish scientific articles as the main author.

Qualifications 

• Bachelor of Science (or equivalent diploma) in computer science or applied mathematics. 
• The ability to concretize and solve open and complex problems.
• Experience in algorithm development and their implementation.
• Experience in scientific software development using C/C++ and possibly Fortran.
• Basic knowledge and, preferably, experience in high-performance computing (shared memory, accelerators, distributed) as well as the related libraries (OpenMP, MPI, CUDA)
• Experience of working with containers such as Singularity; GitHub; CI/CD 

We also require the following soft skills:

• Excellent communication skills in written and spoken English
• Good collaborative skills to work with researchers in the project
