In 2007, the Dublin Institute for Advanced Studies, in partnership with all the Irish Universities and major research institutions, and supported by the HEA under PRTLI cycles 3 and 4, led a national initiative in collaboration with ICHEC and HEAnet to provide the Irish research community with access to true capability high-performance computing. The outcome was an IBM solution based on local Blue Gene /L and Blue Gene /P supercomputers along with remote access to additional Blue Gene facilities abroad. Access to these systems was granted through the National Capability Service, which was operated by ICHEC.
