About BSC
The Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS) is the leading supercomputing center in Spain. It houses MareNostrum, one of the most powerful supercomputers in Europe, was a founding and hosting member of the former European HPC infrastructure PRACE (Partnership for Advanced Computing in Europe), and is now hosting entity for EuroHPC JU, the Joint Undertaking that leads large-scale investments and HPC provision in Europe. The mission of BSC is to research, develop and manage information technologies in order to facilitate scientific progress. BSC combines HPC service provision and R&D into both computer and computational science (life, earth and engineering sciences) under one roof, and currently has over 1000 staff from 60 countries.

Context And Mission
Within the Barcelona Supercomputing Center the Earth Sciences Department, led by Prof Francisco Doblas-Reyes, aims to deliver novel, advanced, and well-evaluated high-resolution global climate models capable of simulating and predicting climate estimations with unprecedented reliability. The successful candidate will be part of the Performance Team a sub-group in the section of Computational Earth Sciences.
This team, composed of 17 members but steadily growing, performs R&D tasks in the field of Earth Science Model (ESM) performance. The team has different goals such as identify model bottlenecks and research how to remove them, adaptation of parallel codes for top HPC platforms around Europe or the use of novel technologies as new accelerators in a proper way.
There is not a clear cut between computational performance and other technical aspects of ESMs. Knowledge of the physical and numerical processes inside the models are necessary to properly assess and improve them. Therefore, members of the team often support the other groups in the departments with technical challenges in the field.
An important task is the evaluation of impacts that certain model developments have. Techniques such as lossy compression, GPU porting, and mixed precision, can have undesired effects. To ensure the correct behavior, one needs a reliable set of diagnostics, and a generic workflow to be applied after changes to the models. To achieve this, members of the performance team work closely together with teams in the department focussed on the scientific aspects of ESMs.
This vacancy is in the context of a project that aims in fostering the collaboration between European and Japanese research centers. The successful candidate will be working in close collaboration with our partners from Japan and has the opportunity to test and deploy applications on Fugaku, one of the largest and fastest supercomputers in the world.
