It is one of the core participants in the European Grid Initiative and the related EGI-InSPIRE project, where it operates a number of pan-European core services and management services for scientific computing; while in EGEE (Enabling Grids for E SciencE) projects series it also ran the Regional Operations Centre for South–East Europe.
