Access to Supercomputing Resources

BSC offers competitive access to MareNostrum through the Spanish Supercomputing Network (Red Española de Supercomputación, RES) and PRACE (Partnership for Advanced Computing in Europe). These two key research infrastructures open periodic calls for Spanish and European researchers to submit their applications. The proposals received are evaluated according to their scientific and technical excellence, and resources are awarded based on the relative ranking received. In addition, European researchers can access MareNostrum and other BSC facilities through the mobility programme HPC-Europa3.


Which resources are available?

BSC offers 80% of the capacity of MareNostrum through RES and PRACE calls. Both infrastructures also provide technical support and training for users. The following table summarises the distribution of MareNostrum resources and corresponding access criteria:

Who can apply?

BSC resources are meant for non-for-profit R&D purposes, and are open to researchers from academia and public research centres. SMEs have also access to PRACE resources under specific conditions through the SHAPE programme.

How to apply?

Supercomputing resources are granted by means of competitive calls.

  • PRACE calls are announced on the PRACE website. You can find further information about the application procedure in the PRACE Application Guide.
  • RES calls are continuously open and proposals are evaluated every four months. To participate in these calls, you need to create an account in the RES Intranet and complete an application form on-line. For further information, please visit the RES website and read the RES Access Protocol.

Mobility programmes

HPC-Europa3 | Pan-European Research Infrastructure on High Performance Computing

The HPC-Europa3 project provides funding for researchers working on computational science to visit HPC centres and/or scientific hosts in Europe to foster new scientific collaborations. Visitors are funded for travel, accommodation and subsistence during their stay (between 3 and 13 weeks), and they are provided with an amount of computing time suitable for the approved project. In addition, they receive scientific and technical mentoring from the host.

Calls for applications are open 4 times per year and published online on the HPC-Europa3 website.

The project HPC-Europa3 is funded by the Horizon 2020 programme; for more information, download the leaflet of the project.
