News, general matters
- LHCC Presentation:
- Comments were directed to:
- How much ROOT progress in the I/O layer?
- When packaging WG would reach conclusions?
- Are other FAs in supporting software (in the wake of the
- New WGs are important in defining concrete work plans.
- LHCC has been asked to offer general support for work
plans, that helps this to happen.
- LHCC have not yet set a date for the review of HL-LHC (may
not be before next summer).
- COMCHA (Spanish organisation for tackling COMputing CHAllenges) Presentation:

- Next meeting,
- Report from Hadrien Grasland about his experience using Spack to
- Workshop at ANL arranged for discuss I/O for exascale. Recommended
re-investigating OpenMP. The HPC community have invested a lot into OpenMP
in recent years and report that it now has much
better support for tasks (which was the main feature that led HEP
to choose TBB in the past). Could be a topic for a future
meeting/workshop (HSF Software Forum).
- Group released its final CWP
Please review if you are interested in this topic.
- Booked in a meeting on Spark use in
LSST for 5
- A few slots still available this year
- Next meeting is “HEP.TrkX: Deep Learning Tracking” on 26
- Graeme may be tied up in the ATLAS IO Review - volunteers to
chair the meeting? David L should be able to do this.
- PyHEP 2018 workshop presentations: most of them now on Zenodo, with
a DOI attributed, see
- Should advertise Gitter and resources more widely (hsf-forum).
- Still trying to find a neutrino community representative.
New Working Groups
- Community nominations now
- Need to write a mandate.
- Vava wanted to make sure the Reconstruction group covers also
software triggers and real-time processing.
- This was in the CWP (strongly!), so yes.
- What about the other group’s names? Are they too abbreviated?
- How to proceed when we have more than 3 people nominated?
- How do we make sure we get a good balance, reflecting the whole
- Elections have been skewed in the past.

- Do we want to have terms for the conveners so there can be
- We should call again for nominations once the mandates are
Re-engineering Computing Workshop
- Indico ready.
- Tweaked the announcement a little.
- It was felt that aspects of how we use generators could also
bring significant gains and should be discussed.
- Dates of 26-27 November at CERN confirmed.
- Should be ready now to circulate widely (please look if you can).
General Matters and Roadmap

is high on his priority list.
- HSF Logo in vector format - reminder of action on Benedikt.
- Next HSF/WLCG workshop:
- Workshop dates fixed for 18-22 March 2019.
- Offer from JLab.
- Offer from BNL to host at Stony Brook.
- JLab looks cheaper for registration ($200 vs. ~$350) and has
cheaper accommodation options (staying in Stony Brook looks
- Pere, Michel supported JLab, easy accommodation.
- Nobody with objection to choose JLab at the meeting. Final check
to be done with I. Collier.
- We wrote an HSF letter of intent to
with an IREU proposal from David Lange and Pete Elmer (funds US
students to come to CERN, working with Openlab in Big Data and
