UNICORE
UNICORE (UNiform Interface to COmputing REsources) is a grid computing technology for resources such as supercomputers or cluster systems and information stored in databases. UNICORE was developed in two projects funded by the German ministry for education and research (BMBF). In European-funded projects UNICORE evolved to a middleware system used at several supercomputer centers. UNICORE served as a basis in other research projects. The UNICORE technology is open source under BSD licence and available at SourceForge.
