LHCC referees meeting with WLCG was Tuesday 1 September.
Andrea Valassi presented a report on the status and plans for generators from the HSF WG. Feedback from the referees was positive and encouraged the group to continue with their work and for the experiments to engage more.
Discussion during the meeting centred on the topic of negative weights being the most important one for the experiments; and that optimisation can focus on the processes which are consume most resources for the LHC: V+jets, ttbar, di-bosons.

Frank Simon has proposed that the next phase of the review looks at common software in much more detail. Three day review anticipated sometime in the window September 27 - October 8, 2021.
More news on the exact charge later, but driven by the idea of a special emphasis on enabling the individual software projects to present plans and status.
This will certainly involve the important generators, Geant4 and ROOT. Other pieces of software could be included too, so we should suggest any that we think are important.
LHCC document was uploaded as a paper to Snowmass. DOI:
Full list of 108 authors was identified (thanks to the WGs for helping a lot with that).
Believe that a number of LoIs were also uploaded where HSF WGs were involved. It would be a good idea to know which ones.
Good opportunity to strengthen links to NP community.
3rd in series of workshops. EIC is a theme this time, which is a well focused community.
We are making good progress with this, hope to conclude soon.
Dates for the C++ course have been set: 12-16 October, https://indico.cern.ch/event/946584/.
Registration opens next Monday 7 Sept 9.00 am CEST. N.B. this iteration is limited to 50 places. If you can’t get a place please still register on the waiting list for eventually grab a free slot and to be informed about new iterations.
Need more volunteers for people to be tutors for afternoon hands-on sessions. (It’s fine if you can only volunteer for a few, or even just one session.)
New meeting format to discuss the fundamental aspects of programming compute accelerators and heterogeneous systems that apply across application domains. The meeting shall serve as a body to introduce basic concepts, infrastructure and tools and to discuss advanced topics of compute accelerators.
First meeting at 1 October 15:00 CEST, https://indico.cern.ch/event/950196/ with presentations on available GPU infrastructure at CERN/IT and WLCG for software engineering and workflow execution.
The first meeting will be recorded for people who cannot attend. During the meeting we will also discuss the least harmful slot for future meetings.
End of GSoC for 2020, there is a meeting today with lightning talks from all of the successful students: https://indico.cern.ch/event/949149/.
TJ presented to Snowmass CF in their end-user analysis kickoff.
Restarting after the break. Not much to report today.
Regrouping after vacation period A long TODO list (we’ll have a meeting among conveners):
What will we do for the November HSF workshop? For the Lund workshop we had the idea of a session of reconstruction techniques for long lived particles…
Started discussing how to come out of hibernation after the holidays… Will likely start with discussions about metadata handling in multi-threaded frameworks.
