gUSE is a set of high-level grid services (including workflow manager, storage). gUSE runs jobs in the DCI Bridge. gUSE services can be hosted on a single host or can be distributed over several server machines to optimize resource usage or increase performance.
gUSE services provide data services (user database, proxy credential database, application code database, workflow database, application history and change log database, etc.) and control services (e.g. job submission, workflow enactment, etc.). gUSE services discover each other using a central gUSE service, the information system.
