INGI Research Meeting

BEgrid is the Belgian research grid infrastructure that resulted from a BELNET initiative in 2003. BEgrid is built using resources from universities and research centers (UCL, KUL, ULB, VUB, UGent, Universiteit Antwerpen…) and the BELNET high-speed network. The organization provides resources for researchers at both national level and international level (like the LHC high-energy physics experiments from CERN). BELNET as NGI (National GRID Initiative) provides central services and represents Belgium in international organizations (like EGI - European Grid Initiative).
