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, and is a hosting member of the PRACE European distributed supercomputing infrastructure. 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 770 staff from 55 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 10 members but steadily growing, performs R&D tasks in the field of Earth Science Model (ESM) performance: its goal is to identify models bottlenecks and research how to remove them. The team has at its disposal cutting-edge performance tools, able to evaluate and represent different performance metrics. Having identified those areas in the code, the experts in the team proceed to modify them without impacting the final results. Possible solutions can go from using more efficient numerical algorithms to modifying the way the model exploits the HPC infrastructure. The approaches can include the porting to new cutting-edge technologies such as accelerators.
Key Duties
  • The successful candidate will work on GPU porting of Earth Science applications, implementing a new GPU base code of the applications run in CPU supercomputers until now. This porting include the use of novel GPU technologies and different tools for the porting. The candidate will also be involved in the development of the department's "common" tools: these include several applications whose interest is shared among different sub-group in the Earth Sciences department and whose number of users can range from small groups to several institutions.
    This position involves close interaction with external collaborators/software vendors as NVIDIA or AMD.
