HSF Coordination Meeting Live Notes =================================== Nota bene - this document is used as scratch pad each week, so it does not keep the minutes for any old meeting for posterity. The minutes are processed each week and put on the [HSF website](https://hepsoftwarefoundation.org/organization/minutes.html), which is the permanent record of the meetings. *Date:* 17 October 2019 *Agenda:* https://indico.cern.ch/event/785601 *Present/Contributors:* Graeme Stewart, Eduardo Rodrigues, Andrea Valassi, David Lange, Attila K, Agnieszka Dziurda, Chris Jones, Daniel Elvira, Witek P, Stefan Roiser, Serhan Mete, Liz Sexton-Kennedy, Mark Neubauer, Kyle K, Nikos Kasioumis *Apologies:* Pere Mato, Caterina Doglioni ## News and General Matters ### Working Groups in 2020 - We discussed the future of working groups in 2020 in the coordination group - The decision was that for the current appointed groups we allow convenors to carry on for another year, as we are very pleased with the outcomes of the groups - Most convenors have said yes to this proposal (thank you very much!) - However, Danilo (Analysis) and Heather (Simulation) have had to step down, due to other commitments - We shall therefore call for nominations to replace them - We also decided that the nomination and appointment process is a successful one and that it should be used more consistently for working groups from now on - So we are also going to call for nominations for convenors in the following groups - PyHEP - Software Tools and Packaging - Physics Event Generators - Training - Current, active, convenors in these areas are stongly encouraged to be nominated, including self-nomination - Note that we decided that *Software Tools* and the *Packaging* group can be usefully merged into one - Three convenors are sought for each group - Areas where the HSF activity has been more sporadic and informal will be rebadged as *Activity Areas* - These will not have formally appointed convenors, but carry on with the input from motivated members of the community - This type of activity is very much encouraged when people would like to start a new interest group (evolution to a working group would be possible, in time) - At the moment we propose that *Visulaisation* and *Quantum Computing* become activity areas - Timeline: - Call for nominations next week until mid-November (post CHEP) - Comments for the community for ~2 weeks after that (end November?) - Appointments to be made in December, if we can, for 2020 - These remain as 1 year, renewable ### Post-JENAS Meeting - As discussed in previous HSF coordination meetings & announced on the mailing list, Caterina organised a [meeting](https://indico.cern.ch/event/852242/) with the Nuclear, Dark Matter, Astroparticle communities as a follow-on from the [JENAS Workshop](https://jenas-2019.lal.in2p3.fr/) - We presented an overview of the HSF - Followed by contributions from nuclear, neutrino, dark matter and ESCAPE communities - HSF-ESCAPE interaction encouraged by APPEC in this context - Very much a first *getting to know you* meeting - The level was quite senior - Feedback was positive, but not immedately clear how to take next steps - Two interesting concrete things came from the discussions with ESCAPE - Training event at LAPP that HEP could be involved in - Software directory that is being built as a deliverable for ESCAPE and could be promoted for HEP software projects - Caterina and Graeme are thinking we can probably continue interactions at the Lund workshop next year, inviting a few key people (not that we do nothing else untl then!) ## Activity and Working Group Updates ### Data Analysis ### Detector Simulation - Next meeting will be on Dec 4th due to CHEP and other experiments' meetings between now and then. We plan it will be on feed-back on use of new geometry tools by experiments. We will contact them soon to fix the agenda. For first meeting next year we would like to invite non-LHC experiments. - There was a [GeantV dedicated meeting on Tuesday](https://indico.cern.ch/event/818702/). There will be a formal write-up of the results obtained. At the end Pere Mato and Philippe Canal presented directions for future activities. We should follow this up regularly next year. - Directions on accelerators are now interesting. Will the GeantV group look at this? No, it will be done with new R&D projects. We know that this is hard and will require new approaches. - Geant Exascale project is exploring this area. - Contact between ORNL and CERN recently ### Reconstruction and Software Triggers - Next meeting, targeting "Algorithmic approaches and data structures to efficiently exploit many-core architectures" moved from 9th October to "after CHEP" due to unavailability of the speaker. ### Software Tools - In case you missed the TAU talk last Monday: https://indico.cern.ch/event/845622/ - To be followed up with a hands-on session, most probably will take place on January 20th at CERN: - Imperative to focus on HEP use cases. - It might be nice to give priority to accelerator related examples. - Please let us know if you have a workload that you'd like us to focus on. ### PyHEP - PyHEP 2019 workshop now taking place in Abingdon, U.K., 16-18 Oct., see https://indico.cern.ch/e/PyHEP2019.  ### Frameworks - Will have a meeting next Wednesday. Plan to have presentation from DUNE. Workflow is quite different from HEP collider experiments. ### Training - [Software Carpentry at CERN, 27-29 November](https://indico.cern.ch/event/834411/) - A lot of progress in organising the event - Registration opens tomorrow... ### Event Generators - No meetings yet after the summer - Have not pinged or heard back from the Argonne team working on Madgraph on GPUs - Josh McFayden is working on a setup to allow standalone runs of several generators, which eventually may be incorporated into the HEP-workloads benchmarking suite using Docker containers - Steve Mrenna will give an overview of activities at the Latin American workshop in Mexico ### Event Delivery Forum ### Packaging - [Meeting last week](https://indico.cern.ch/event/848215/) had a very useful discussion on best practices for package relocatability from Ben Morgan - There are a few packaging contributions we know of at CHEP - Plan to have another meeting before the end of the year ### Quantum Computing ### Visualisation ## Workshops ### Next HSF/WLCG Workshop - Caterina is offline today, but happy to start the discussion on progress with logistics, program... if we want a dedicated kick-off meeting that we then summarize, we could do next Thu in the HSF slot? ### Pre-CHEP, Analysis Systems: From Future Facilities to Final Plots (2-3 November) - Event is now very well planned - Just putting the finishing touches to the interactive sessions to try and get these to go smoothly - All topics have confirmed *animators* to help the discussions - We will try to have group coordinators - We will circulate information shortly to all participants so that people know what to expect ### Latin American Workshop on Software and Computing Challenges in HEP (Mexico, Nov 20-23) - Good attendance expected (32 people registered): Latin American PIs, international speakers, students - Workshop URL <https://indico.cern.ch/event/813325> - Giving final touches to the agenda - We are missing three important topics/speakers: - Detector simulation (Pere, any progress identifying a speaker? HSF simulation converners consulted, posibility of a CERN speaker) - Reconstruction (IRIS-HEP will support travel if speaker is US-based). D. Lange, P. Elmer, G. Watts trying to find a suitable speaker from an NSF-funded institution. Alternatively, Giuseppe Cerati is available and willing to do it. - "HPC lanscape for science applications". We are trying to get someone from Oakridge. Not clear we will succeed. Ideas? - Everyone: you still have time to register and attend! Excellent opportunity to network with Latin American collaborators. ## AOB - We experimented with switching to CERN's collaborative Markdown editor, CodiMD, for the meeting minutes this week - More convenient to write notes in the format needed by the website than to have to convert from Google Docs - Unfortunately it seems that lightweight accounts cannot edit these documents on the CERN service - Options: - Get CERN to allow lightweight editing - Switch back to Google Docs - Use the CodiMD demo service, e.g. with a [note like this one](https://demo.codimd.org/COseSwVnQRuYOAWpHC756Q?both) - Notes can be set to be editable by anyone at all (freely) or by logged in people (editable) - to login a GitHub account can be used - Nikos (CERN IT): want to understand the needs - In a nutshell, we have HSF people who do not have full CERN accounts, so we do need something that everyone can contributed to - Federated identity is advancing fast - eduGAIN would be an option, as all of our people should have institutional credentials of some kind - Next coordination meeting... - CHEP is very soon, do people want to have a meeting on 31 October? - Or wait till afterwards, 14 November
