Fenix: Distributed e-Infrastructure Services for EBRAINS

Abstract The Human Brain Project (HBP) ( https://humanbrainproject.eu/ ) is a large-scale flagship project funded by the European Commission with goal of establishing research infrastructure for brain science. This currently being realised and will be called EBRAINS https://ebrains.eu/ ). wide ranging services communities require diverse access, processing storage capabilities. As result, it strongly rely on e-infrastructure services. HBP led to creation Fenix https://fenix-ri.eu/ ), collaboration five supercomputing centres, who are providing set federated EBRAINS. architecture has been designed uniquely address need spectrum services, from high performance computing (HPC) on-demand cloud technologies identity access federation, facilitating ease usage distributed resources. In this article we describe underlying concepts an audience computational science end-users developers domain-specific applications, workflows platforms To exemplify use Fenix, discuss selected cases demonstrating how researchers can offered these resources obtained.
