  1. HEP GRID use cases Common GRID use cases F.Harris, J.Templon, J.J Blaising DataGrig Barcelona

  2. User Requirements Simulation Data reconstruction Data Analysis User requirements for production type work were collected by EDG WP8 and refined by the LCG RTAG -> HEPCAL document. DataGrig Barcelona

  3. User Requirements • HEPCAL document describes: • macro use cases • simulation, data transformation, production • mini uses cases • which are used to implement the macro u.c • They were evaluated by WP8 and the results • are documented in D8.3. • Data Set (DS) = file DataGrig Barcelona

  4. Identifier UC#dstran Goals in Context : Creation of new data set starting from input data Actors :User, Production manager Triggers : Need of output data for further processing Included Use Cases:Grid authorization, Grid login , Browse Grid resources, Steer Job, Job resources estimation, Set Job environment Job submission, Job monitoring, Job cancel DS access (Find PFN, copy, open); DS upload (copy and register), DS transfer, DS register DS replication; DS MD Browse, DS delete Job output DataGrig Barcelona
