  • Senior technical leader – co-design activities around RISC-V (CS & App.Dept) (RE2-3)

    Context And Mission

    The Laboratory of Open Computer Architecture (LOCA) at Barcelona Supercomputing Center aims to break through traditional disciplinary silos and lead the research and development of European open software and hardware stacks based on the RISC-V Instruction Set Architecture for Exascale and beyond. This will be done with BSC’s scientific departments to produce highly optimized grand challenge scientific applications in climate modelling, personalized medicine and energy. LOCA spans topics ranging from Computer Architecture to System Software to Applications, in both traditional HPC and emerging High-Performance Data Analytics (HPDA) and is working towards EU autonomy in HPC technologies. BSC is looking for a co-design expert in open software to contribute to this aim.

    This is being done with the support of BSC’s Severo Ochoa award for the 2023-26 period, which aims to boost BSC capacities to codesign hardware and software, maximise internal and external synergies, expand international leadership, provide best-practice career development with strong gender actions, and enhance societal engagement and technology transfer. (

    Main goal:
    Apply domain expertise and support to the application departments focused on the identification and exploitation of tools, mechanisms that can help on the characterization, optimization, and co-design of HPC applications in collaboration with experts on domain-specific scientific applications (Life, Earth, Applied Engineering) and open hardware architectures.

    Key Duties

    • Identify tools, methodologies, workflows, etc. of interest for Computer Science research department that can benefit from other groups/departments’ support.
    • Help to characterize the core applications for Life, Earth and CASE departments by using the resources available at BSC and contribute to the definition of Key Performance Indicators (KPI) for improving their performance.
    • Work to optimize domain applications for BSC-designed RISC-V HPC processors in collaboration with the multi-disciplinary team and contribute to enhancing the full HPC stack.
    • Identify potential co-design activities being performed within multiple projects in the relevant application department, track the work, inform on relevant aspects, promote synergies and exchange of best practices.
    • Co-organize sessions to disseminate the knowledge, progress, and projects of the Severo Ochoa, in the shape of workshops and/or seminars.
