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.
