HSF Weekly Meeting #162, 28 March, 2019

Present/Contributors: Graeme Stewart, Stefan Roiser, Witek Pokorski, Andrea Valassi, Eduardo Rodrigues, David Lange, Javier Cervantes, Andrei Gheata, Paul Laycock, Pere Mato, Gloria Corti

News, general matters

• Reminder that CHEP2019 abstract submission opened a few weeks ago - deadline for submission is 13 May.

Google Summer of Code 2019

• We are in the application phase (until 9 April).
  • Mentors can interact with students at this time.
  • Students are asked to tag their proposals, however, as an umbrella organisation, we can only set 10 tags, so the list is incomplete. It’s actually ok to leave this blank (have enquired to Google to see if this can be changed).
• Very important to check that students don’t have any significant commitments during the coding time (>1 week is a red light - don’t consider them).
  • This statement needs to be part of the proposal.
• Noted that proposals can be very different (e.g. one very concrete, another with a lot of fluff).
  • No templates - concise is better (will also be judged by Google).
  • Judge and give feedback on what you think is better for your project.
• We still need a few more people to serve on the Advisory Committee.
  • Pere volunteers.
  • Please let us know if you are interested in also helping.

Google Season of Docs

• https://developers.google.com/season-of-docs/.
  • This is a technical writer project.
• GSoC coordinators asked if we would run this too.
  • We think to start small - 2-5 projects? Still feeling our way in this.
  • Mentors would need to invest the time to understand the process and how to get the best from it.
  • Our code is very technical - would need to know how to help a writer produce useful documentation for users.
• Get in touch with the coordinators if you are interested.

HSF/WLCG/OSG Workshop

• 246 people registered in the end (plus other “walk up” registrations).
• Local organisation was extremely good - thanks to Amber and the JLab staff.
  • Vidyo was a bit weak, but we managed.
• Thanks to everyone for coming and contributing to the meeting.
  • General feedback has been very positive.
  • Notes were good and helpful.
• Duplication between tracks was an issue and could be improved.
  • Too many things organised late in the day?
• Having parallel sessions between WLCG and HSF is an issue, at least for some people.
  • Would need to be careful with this - higher level overviews?
  • It was better to not have HSF sessions in parallel (cf. Naples).
  • We really do need 5 days! Next time should rethink the plenary slots and share more information in advance.
• We plan to have a proper round up of workshop issues in one of the next meetings.
  • Doodled for the best date, 11 April seems favoured.
• We should do a summary newsletter
  • Graeme to do first draft and circulate it.

Activity and Working Group Updates

Detector Simulation

• Advertised two next simulation topical meetings, 8 May and 12 June.

Event Generators

• We had our first three bi-weekly meetings and we’ll have the fourth one today. We are concentrating (and making progress) on the ATLAS/CMS accounting comparison. We also had a first discussion on sharing generator settings (and possible samples) for the specific case of SUSY signal samples.
• There was a talk about MadGraph on GPU at JLab. We’ll try to follow up further.

Packaging

• Meeting on 27 March (minutes):
  • Review of JLab meeting.
  • Update from SuperNEMO on building with Spack.
  • Discussed issues with ROOT recipe in Spack.
• Next meeting 24 April.

CWP

Roadmap

• The Roadmap has now been published in Computing and Software for Big Science:
  • https://doi.org/10.1007/s41781-018-0018-8
• Many thanks to all of those who contributed to the process and this very healthy final outcome.
• See https://hepsoftwarefoundation.org/organization/cwp.html for links and citation advice.
• We should send a message to the CWP lists.

AOB

• OpenLab nVidia workshop happened on Monday:
  • Nice introduction to the ecosystem and boxes they are building.
  • CUDA and ML topics were introduced.
  • Idea is to hold follow-up workshops in the future.
• As we decided that as the full JLab follow-up will be 11 April, next week’s meeting (4 April) is cancelled, unless anything urgent comes up.
