News, general matters


There are a number of places where HEP is coordinating to help in the current situation:

We absolutely encourage HSF members to find useful ways to apply their talents!

Google Summer of Code 2020

We need to reboot the GSoC Advisory Committee (last year it was Pere Mato, Pete Elmer, Michel Jouvin). See the mandate. They should be able to rank the projects assuming we get less slots than projects we could run.

News from GSoC Admins:

Q. Can projects with many good proposals be split in two? No, they can’t.

LHCC Review of HL-LHC Software and Computing

Reminder: LHCC will review software and computing plans for the HL-LHC, Amber Boehnlein (JLab) will chair. Five 20 page documents provided as input to the committee, from ATLAS, CMS, WLCG, DOMA and from Common Tools and Community Software (the HSF takes care of the later)

There will be a relatively short virtual meeting in the week of 18 May, with follow-up reviews later.

HSF Draft Document

HSF review meeting will be Thursday 16 April, where points needing further discussion will be tabled

Current list of open points for each section:



Event Generators

Detector Simulation

Reconstruction and Software Triggers

Data Analysis


Working Group Updates

Detector Simulation

Reconstruction and Software Triggers


Software Training

Event generators


We will continue/complete our survey of experiment frameworks next week with a presentation from Belle II. We also will discuss what could be targeted for the HSF/WLCG virtual workshop in May.


HSF/WLCG 2020 workshop

21-25 September has been booked in Lund, but this is evidently still subject to later confirmation

New Architectures, Portability, and Sustainability

HSF WLCG Virtual Workshop on New Architectures, Portability, and Sustainability

The HSF and WLCG have organised this virtual event to focus on the challenges and opportunities of new computing architectures. This is a critical and highly relevant topic for HEP where much progress is being made, but there remain many open questions to discuss. Adapting to the needs of the communty to host more virtual participation events we will hold this meeting over 3 days, from 16-18h each day, to maximise the opportunity to participate. Three themes will be addressed across the three days: - Application Software - Processing Frameworks - Validation and Accounting (including Benchmarking)

We will be exploring new ways to interact effectively during events like these, with more emphasis on having material available early and the opportunity to raise discussion points in advance.

Main speakers identified, inviting them now. The goal is to have public announcement of the virtual workshop and the preliminary agenda next Wednesday, after Easter and the next preparation meeting on Tuesday evening.

We ask that people register so that we can gauge the level of interest.

Prepared a virtual meeting guide to try to make the event work as well as possible, more suggestions and feedback very welcome here (we are treading new ground).


Next Meeting

Happy Easter!
