Technical student started this week to work on ROOT graphics
ATLAS and CMS librarian board tomorrow
Google Summer of Code - mentors provided input to reviewers. Number of slots will be decided then
Concluded on date (30.5.) for librarians workshop (TODO: add link)
One morning
Added a new package on request by ALICE (Apache Arrow)
Upgrade of BLAS package; TMVA depends on blas (see minutes of LIM)
Dev3 problem; wrong config in jenkins
CERNVM
CernVM 3.7 release - consolidation release just before easter
End of spectre/meltdown patches
Integration testing for new filesystem release
Simulation

IT
ARM 64 question was followed up;
In LIM people asked for ARM64; computing coordinators not interested according to Tim Bell; needs to be clarified;
Would like to have puppet infrastructure for reproducibility; not sustainable for IT;
Marco Cattaneo: currently R&D. need a few machines for test;
Openlab machines to disappear; TechLab has only a small number of machines
No need for full production quality service
Patricia will contact Helge to clarify
ATLAS will use ARM in online config. Asking for a Linux to use that provides some support.
Giulio: wouldn’t docker be enough for now?
SSO for GitHub - is now waiting for a new SSO implementation that is not reliant on Microsoft.
HSF
Successful workshop last week in Naples with WLCG (https://indico.cern.ch/event/658060/). Now deciding on the most important points to follow up and the best ways to do that. Many communities are quite well organised, but some require more bootstrapping. HSF should organise an ‘activity catalog’ and be a point of information exchange (broaden scope of 15h meetings).
Feedback on having software and computing together was very positive.
Benedikt will give a summary of the WS in the next EP-SFT meeting.
3 May for next meeting.
