Compute Area Marco Cecchi Massimo Sgaravatto

EMI Execution Service (EMI- ES) Compute Area EMI Execution Service (EMI- ES) Feeling that there is not a common vision. EMI-ES just as a prototype (since the goal is to implement and support something really standard) vs. EMI-ES as a production system Clarify EMI-ES support in WMS Find the right balance among objectives targeted to standardization, harmonization, removal of duplications, and requests coming from our user communities, otherwise there is the risk to lose some existing customers Pilot jobs Clear message from the WLCG WM TEG that the LHC experiments are all referring to pilot based frameworks and intend to keep following this path We should focus in this area, to address some existing issues Enhancing the functionality of the CE to implement a generic, non VO specific pilot factory Standardization of pilots and pilot based frameworks ?

Compute Area Some items in the workplan for the third year are risky There is not a clear understanding (yet) on what should be done e.g. for: Implement cloud strategy Integrate EMI delegation in compute services Implement EMI unified solution for service monitoring Some other items not in the workplan where work should be done: Support execution on user-defined virtual environments Possible implementations: WNODES, ... Improve batch system support in CREAM (SLURM and Condor) Support workflow in gLite WMS CREAM-LB integration
