DIRAC is an interware, meaning a software framework for distributed computing.
copied from cf-staging / dirac-gridDIRAC (Distributed Infrastructure with Remote Agent Control) INTERWARE is a software framework for distributed computing providing a complete solution to one or more user community requiring access to distributed resources. DIRAC builds a layer between the users and the resources offering a common interface to a number of heterogeneous providers, integrating them in a seamless manner, providing interoperability, at the same time as an optimized, transparent and reliable usage of the resources.
DIRAC has been started by the LHCb collaboration who still maintains it. It is now used by several communities (AKA VO=Virtual Organizations) for their distributed computing workflows.
