Welcome to MultiXscale!
EuroHPC JU Center of Excellence
MultiXscale is a European High Performance Computing Joint Undertaking (EuroHPC JU) Center of Excellence in exascale-oriented application co-design and delivery for multiscale simulations. It is a collaborative 4-year project between members of the CECAM network and the EESSI community that will allow domain scientists to take advantage of the computational resources offered by EuroHPC JU.

Partner Networks

CECAM is a scientific network started in 1969 to promote fundamental research on advanced computational methods.
It provides the scientific backbone to support the project with three showcase areas for multiscale modeling:
Advanced parallel aerodynamic code for rotor aeroelastic analyses
High-power battery applications: Towards enhanced supercapacitor
Biomedical applications of ultrasound: Improving diagnostics and guiding drug delivery
EESSI is a tool developed by a network of HPC community partners whose goal is to build a common stack of scientific software installations for HPC systems.
It provides the technical backbone to the project, including CI/CD capabilities and hardware support across EuroHPC resources.
EESSI aims to reduce the technical burden on developers and end-users of scientific applications.
