Board being organized for the beginning of April
Program of work presentations/discussions
5,12,19 March for simulation, CernVM and services, and ROOT (https://indico.cern.ch/category/266/)
Everybody is invited to the meetings - ask Pere if you don’t get the SFT group meeting invitations
Workshop tomorrow (https://indico.cern.ch/event/696066/)
Advisory to IT management for R&D projects in the context of OpenLab and Techlab. Resources, priorities , ensure that R&D activities are properly documented, etc.
The composition is experiments computing coordinators, SFT group leader and leaders of the various IT groups/projects
LCG_93 has been released (also with Python 3). Some issues for LHCb, but think they are all solved.
Binutils is still a “manual” extra installation in this release..
For LCG_94 RPM dependencies on binutils will be included to automate the whole process (used by ATLAS).
LCG_94 will wait for the next ROOT release (Pere thinks there is a patch release coming soon)
New davix requested by ATLAS for LCG_88.
Workshop being organised (May, June - Doodle: https://doodle.com/poll/wx98gxehz3vmc4aa) to gather input from the experiments about their needs in a bit more depth than can be gathered in the LIM itself.
This will help define the longer term strategy.
2-3 year roadmap.
You are all invited.
Link to HSF activities.
Clang 5.0 requested by LHCb. Causes a lot of failures right now in dev3 -> following up.
Appliance release 3.7 is in the pipeline. Currently being tested internally. Will go to public testing next week. Needed for kernel upgrade for CERNVM 3.
CVMFS 2.5 release well in hand. 25 smaller issued to be resolved.
Will support multi-transactions.
Improved backup strategy being developed with IT.
New patch release 10.4p1. CMS wanted this, but went to production with 10.4 anyway. LHCb needed custom optical properties (was removed by mistake in 10.4). Supports C++17 (needs CMake 3.8). Work plan is now available. Will be discussed in 10 April G4 Technical Forum.
Charles - nothing to report for CORAL and COOL.
Nothing to report.
Nothing special to report.
Nothing more to report.
Nothing more to report. Finalising data taking releases.
Minor issues with G4 10.4. Had to adapt to a change of CMake variable for CLHEP.
Was not seen in LCG builds.
IT TUM 28 May. Q. Are other linux distros being considered? Only CentOS7.5. No other distributions being considered (has 10 year LTS).
Better support for ARM64 architectures seems to be the only active request (this means puppet and other supporting services).
Naples workshop in just over 1 week. Well prepared, looking forward to many discussions about the development plans for the next decade.
Next meeting 5 April.
