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

The mission revolves around Alya, a high-performance computational mechanics code developed within the CASE department to solve complex coupled multiphysics/multi-scale/multi-domain problems, which are mostly coming from the engineering realm. Among the different physics solved by Alya, we can mention incompressible/compressible flows, non-linear solid mechanics, chemistry, particle transport, heat transfer, turbulence modelling, electrical propagation, etc.
For a couple of years, the development of Alya follows a CI/CD scheme based on Gitlab tools (issues, merge requests, etc.), pipelines, and API. The complexity of the CI/CD pipeline has increased with the addition of new features, the integration of multiple third-party libraries, and the deployment of Alya on new platforms that require more “exotic” compilers or compilation options. We want to optimize the pipeline as much as possible to reduce the potential bottlenecks hindering development and preventing daily code integration. In particular, much effort will be put into optimizing the regression test framework that runs thousands of tests on various HPC platforms.
The candidate will participate in deploying and maintaining the GitLab infrastructure, i.e. the physical machines and the OpenStack virtual machines running the self-hosted GitLab server, as well as the GitLab runners executing the pipeline jobs.
The candidate will also be involved in improving the build system based on CMake and help the developers integrate new third-party libraries and extend the compilation options. Work will also be focused on improving the architecture of Alya and providing support for git and GitLab to the developers and the users.
