HSF/WLCG Workshop
11+
=================
12+
- ### General points
13+
- 196 people registered.
14+
- Rooms for each of the sessions have now been put into Indico.
15+
Note that plenary sessions are all in the hotel; during the
16+
parallel sessions we use the main hotel room plus 2 rooms
17+
in the conference centre. The two venues are 200m apart.
18+
- We have coffee available in both locations when necessary. All
19+
the lunches are at the conference centre.
20+
- Vidyo Rooms are created (one for each location). Graeme is the
21+
owner. If everyone knows the moderation PIN is this enough to
22+
manage these?
23+
- ### Outcomes
24+
- First list of general questions that convenors could consider
25+
when thinking about their sessions. Aimed at identifying what
26+
projects we can realise after Naples; and for those we cannot,
27+
how do we enable them?
28+
- What projects were identified that we can advance from the
29+
CWP Roadmap as a community?
30+
- How will these be followed up on?
31+
- Are the timescales for the project well defined?
32+
- Is the project sufficiently covered for effort right now?
33+
Do we need to ask for further involvement (other
34+
experiments or groups)?
35+
- Does the project have resource needs that are not yet
36+
covered? (Infrastructure and funding.)
37+
- What projects were identified that we can't advance from
38+
the CWP Roadmap as a community?
39+
- Are these critical items for the next decade?
40+
- Can a case for funding these items be developed?
41+
- Are there links with other (non-HEP) communities...
42+
- That are established or that would be desirable?
43+
- How will the projects developed improve our community's use
44+
of developer effort between experiments? Can we enhance
45+
that?
46+
- What's the best way of organising ourselves (meetings,
47+
workshops, mailing lists) to work effectively in the next
48+
few years?
49+
- Post CWP R&D: How does HEP-TrkX connect with ACTS (for example)?
50+
How do these projects work together? This is an important
51+
question.
52+
- R&D that will inform the ATLAS and CMS computing TDRs is a very important milestone.
53+
- HSF could curate a map of projects, make sure they are well
54+
known.
55+
- Good for projects to have information pages.
56+
- Knowledge Base is still there, but doesn't seem to be well
57+
maintained or curated at the moment (updated curation is
58+
crucial!).
59+
- Motivation is a bit back to front - it's the things you
60+
don't know which are the ones you care about.
61+
- Could we take a [Depsy](http://depsy.org/)
62+
like approach about finding cross-links between
63+
software projects?
64+
- CMS have worked on a list of projects they are involved in,
65+
some EU funded.
66+
- Have regular project presentations - take inspiration from the
67+
much loved Concurrency Forum.
68+
- Want to address what the meaning of an HSF project actually is -
69+
what value can HSF bring to projects that come under the
70+
umbrella.
71+
- Source of advice and expertise.
72+
- Means of raising awareness.
73+
- Do we help with funding applications? Yet to be proven, but
74+
surely does no harm.
75+
- Discussion on this foreseen in Software Development session.
76+
- ### Monday
77+
- Opening Plenary
78+
- Not much change - Taylor Childers will contribute to the US
79+
funding situation talk
80+
- Technology Watch
81+
- Call for input broadcast to the community.
82+
- HEP Use Cases
83+
- Need to go through the list to find speakers. Liz/Daniel
84+
will help follow up with Erica.
85+
- ### Tuesday
86+
- Data Management/Lakes
87+
- The data management sessions will have a small adjustment
88+
(One talk of 5', highlights for XDC). Otherwise the agenda
89+
is confirmed.
90+
- Frameworks and Infrastructure
91+
- Iterating on question/themes for session speakers.
92+
- Training (Parallel)
93+
- Speakers invited, all have accepted: they were provided a
94+
template to help them delivering homogenous talks from
95+
their individual perspective. This will facilitate the
96+
round table: needs and proposal will be based on an equal
97+
footing. First outcome should be a proposal on how to
98+
organize the "Training" activity by joining forces among
99+
existing (and future) initiatives.
100+
- DPHEP (Parallel)
101+
- Good agenda - not clear if all speakers are found.
102+
- Workload Management (Parallel)
103+
- For the workload management session all speakers are
104+
effectively confirmed.
105+
- Analysis Facilities and Use Cases
106+
- NTR.
107+

121+
- Discussion on OpSec section on Monday this week, slide
122+
preparation underway.
123+

Activity updates

180+
Licensing
181+
---------
182+
- HepMC3 authors agreed to assign copyright to CERN and apply an LGPL
183+
license. CERN copyright is recognised as using the lab as a
184+
favourable copyright holder for the community. Authors
185+
acknowledgement file makes sure contributors get appropriate
186+
credit ("git log" tells all, of course!).
187+
- Could HepMC3 become an HSF project? Would need to improve a few
188+
technical points, but in principle it's a good candidate.
189+
(N.B. HSF is not a legal entity, can't hold copyright.)
190+
- Discussion on copyright - authors should decide who the appropriate
191+
entity is to hold this (associated labs are good). Aim for simplicity is our
192+
advice - one copyright holder is best.
193+
194+
Packaging
195+
---------
196+
- Meeting
197+
[yesterday](https://indico.cern.ch/event/708110/).
198+
Converged on use cases document and had an interesting discussion
199+
on Spack's missing/awkward features.
200+
- Next meeting [21
201+
March](https://indico.cern.ch/event/712739/). Look at
202+
the use of Nix in LHCb.
203+
204+
AOB
205+
===
206+
- Agreed that getting DOIs for technical notes is a good thing to do.
207+
Just need to give people practical advice on this (Eduardo).
208+
- US conceptualisation on Research Software Sustainability Institute
209+
starting. Workshop in Berkeley to kick off next month. See
210+
[http://urssi.us/](http://urssi.us/). Mark Neubauer will
211+
attend.
