- 196 people registered.
- Rooms for each of the sessions have now been put into Indico.
Note that plenary sessions are all in the hotel; during the
parallel sessions we use the main hotel room plus 2 rooms
in the conference centre. The two venues are 200m apart.
- We have coffee available in both locations when necessary. All
the lunches are at the conference centre.
- Vidyo Rooms are created (one for each location). Graeme is the
owner. If everyone knows the moderation PIN is this enough to
- First list of general questions that convenors could consider
when thinking about their sessions. Aimed at identifying what
projects we can realise after Naples; and for those we cannot,
how do we enable them?
- What projects were identified that we can advance from the
CWP Roadmap as a community?
- How will these be followed up on?
- Are the timescales for the project well defined?
- Is the project sufficiently covered for effort right now?
Do we need to ask for further involvement (other
experiments or groups)?
- Does the project have resource needs that are not yet
covered? (Infrastructure and funding.)
- What projects were identified that we can’t advance from
the CWP Roadmap as a community?
- Are these critical items for the next decade?
- Can a case for funding these items be developed?
- Are there links with other (non-HEP) communities…
- That are established or that would be desirable?
- How will the projects developed improve our community’s use
of developer effort between experiments? Can we enhance
- What’s the best way of organising ourselves (meetings,
workshops, mailing lists) to work effectively in the next
- Post CWP R&D: How does HEP-TrkX connect with ACTS (for example)?
How do these projects work together? This is an important
- R&D that will inform the ATLAS and CMS computing TDRs is a very important milestone.
- HSF could curate a map of projects, make sure they are well
- Good for projects to have information pages.
- Knowledge Base is still there, but doesn’t seem to be well
maintained or curated at the moment (updated curation is
- Motivation is a bit back to front - it’s the things you
don’t know which are the ones you care about.
- Could we take a Depsy
like approach about finding cross-links between
- CMS have worked on a list of projects they are involved in,
some EU funded.
- Have regular project presentations - take inspiration from the
much loved Concurrency Forum.
- Want to address what the meaning of an HSF project actually is -
what value can HSF bring to projects that come under the
- Source of advice and expertise.
- Means of raising awareness.
- Do we help with funding applications? Yet to be proven, but
surely does no harm.
- Discussion on this foreseen in Software Development session.
- Opening Plenary
- Not much change - Taylor Childers will contribute to the US
funding situation talk
- Technology Watch
- Call for input broadcast to the community.
- HEP Use Cases
- Need to go through the list to find speakers. Liz/Daniel
will help follow up with Erica.
- Data Management/Lakes
- The data management sessions will have a small adjustment
(One talk of 5’, highlights for XDC). Otherwise the agenda
- Frameworks and Infrastructure
- Iterating on question/themes for session speakers.
- Training (Parallel)
- Speakers invited, all have accepted: they were provided a
template to help them delivering homogeneous talks from
their individual perspective. This will facilitate the
round table: needs and proposal will be based on an equal
footing. First outcome should be a proposal on how to
organize the “Training” activity by joining forces among
existing (and future) initiatives.
- DPHEP (Parallel)
- Good agenda - not clear if all speakers are found.
- Workload Management (Parallel)
- For the workload management session all speakers are
- Analysis Facilities and Use Cases
- Programming for Concurrency and Co-Processors
- Visualisation (Parallel)
- Performance and Cost Modeling (Parallel)
- Discussed yesterday, seems well planned.
- Software Development (Parallel)
- Asked Sandro about static analysers. Will discuss about the
- Simulation (Parallel)
- Talks in good dhape. John can’t be physically in Naples (need a second person to
- Security (Parallel)
- Discussion on OpSec section on Monday this week, slide
- Technical Discussion on Frameworks (Parallel)
- Some problems organising this session. Now envisage more of
a follow on discussion based on CWP and continuation of
the Frameworks and Infrastructure session.
- Closing Plenary
- Need to chase up SKA talk.
General Matters and Roadmap
- CERN Courier article got a few improvements after Ed Board
feedback. Will appear in April edition.
- Will circulate the proof to the startup team.
- Symmetry magazine article status we are not sure about - to be
Publication strategy for Individual WG Papers
- Ready to go to arXiv now, with a finalised author list.
Merged into hsf-documents repo.
Software Trigger and Event Reconstruction
- Done. Needs merged into hsf-documents repo.
Data Organisation, Management and Access
- Current contents considered in very good shape
- Plan is to convert to LaTeX in the coming days, check the
consistency with the global roadmap next week and call for
authors as soon as the content is final
Data and Software Preservation
Data Analysis and Interpretation
- Added abstract (was missing) and completed editing pass.
Will make pull request with the latest changes and then
get sign-off from authors in preparation for submission.
Event/Data Processing Frameworks
- A version went to the github document repo. Still needs more
Careers, Staffing and Training
- Want to incorporate thoughts from Naples and revise, given
the wider community involved there.
Facilities and Distributed Computing
- Waiting until after the WLCG strategy document is done.
- Should discuss this at Naples and see how to move forward.
- HepMC3 authors agreed to assign copyright to CERN and apply an LGPL
license. CERN copyright is recognised as using the lab as a
favourable copyright holder for the community. Authors
acknowledgement file makes sure contributors get appropriate
credit (“git log” tells all, of course!).
- Could HepMC3 become an HSF project? Would need to improve a few
technical points, but in principle it’s a good candidate.
(N.B. HSF is not a legal entity, can’t hold copyright.)
- Discussion on copyright - authors should decide who the appropriate
entity is to hold this (associated labs are good). Aim for simplicity is our
advice - one copyright holder is best.
Converged on use cases document and had an interesting discussion
on Spack’s missing/awkward features.
- Next meeting 21
March. Look at
the use of Nix in LHCb.
- Agreed that getting DOIs for technical notes is a good thing to do.
Just need to give people practical advice on this (Eduardo).
- US conceptualisation on Research Software Sustainability Institute
starting. Workshop in Berkeley to kick off next month. See
http://urssi.us/. Mark Neubauer will
