Impact of end of EMI+EGI-SA3• April 2013:
• EMI project finishes• EGI-Inspire-SA3 finishes (mainly CERN
affected)• EGI-Inspire continues until April 2014• EGI.eu continues indefinitely
• Impact on WLCG & CERN IT

Impact in IT• Significant reduction in staff in ES and GT
groups (~33% and ~45% reduction resp.)• No prospect of additional equivalent funding in
the near future
• Re-prioritisation of functions is unavoidable

Evolution of functions• CERN has some ongoing commitments to EGI.eu and
NGIs• Esp since we expect EGI to support WLCG• These are in-line with what we need for LHC
• Must focus remaining effort where can have the most impact• Better in areas that benefit >1 experiment;• Less “labelled” staff (dedicated to experiments)
• EMI:• Complex infrastructure used by EMI no longer required
• Middleware support process under active discussion with partners• IT responsible for DM m/w + info system – must be maintained

What IT must do• WLCG operations, service coordination, support
• Consolidate related efforts (daily ops, integration, deployment, problem follow-up etc)
• Broader than just CERN – encourage other labs to participate
• Common solutions• Set of activities benefitting several experiments. Coordinates experiment
work as well as IT-driven work. Experiments see this as strategic for the future; beneficial for long term sustainability
• Grid monitoring• Must be consolidated (SAM/Dashboards). Infrastructure becoming more
common (also with AI mon); focus on commonalities, less on experiment-specifics
• Grid sw dev+support• WLCG DM tools (FTS, DPM/LFC, Coral/COOL, etc), information system;
Simplification of build, packaging, etc. open source community processes; (See WLCG doc)

What can no longer be supported
• Support for Ganga core • Agreed with Ganga collaboration
• POOL • Now only used by ATLAS; they assume responsibility
• Activities where no interest from experiments:• Gridview, SE-catalog sync, … will be stopped
• Experiment-specific customisations of (e.g. dashboards, SAM tests)• Move to experiment teams
• Previous level of dedicated expert support to experiments unsustainable• Understood by ATLAS/CMS; issue for LHCb and ALICE• Some reduction in this effort already – but…

Notes• There is no simple definition of "common solutions"
- actually this can be part of many different activities, but a coordination of this is required, as well as available effort to work on priority projects
• Support for middleware:• Proposal for methodology under discussion (document)
with EMI and EGI as well as within WLCG• Relies on on-going commitments from m/w
development partners
• Encouraging broader community involvement and support where possible (e.g. WLCG Operations, middleware such as DPM, …)

Potential for future projects• Only in 2014 at the earliest• Must be broader than just HEP• Must involve industrial partners (public-
private partnerships)• Continued development of grids will not be
feasible projects• And:
• We must have commitments across the board this time – not IT alone
