ITEMS

1) International resources [DB/PC]
A discussion was held about matters emerging from the last MB.

2) 1e6 Run [DB/All]
DB forwarded 2 emails to the group prior to the meeting about the ongoing discussion around this work.
The group continued discussions around this opportunity for collaboration work with GridPP.

3) GridPP48 Ambleside [SS & JS]
– The agenda is now almost finalised. SS is waiting to hear if someone from LZ will attend and present a talk.
– There are 61 registered attendees, and so space for 3 more people. LZ and people arranging sponsors have been told we would need final numbers by the end of this week.
– Practical details have been sent to the venue and JS to continue to liaise with Helen.
– Roger confirmed the Priest Hole can accommodate 64 attendees.

Actions:

  • JS and SS to liaise with Roger and help with pre-ordering
  • JS and SS to investigate parking at the venue. There is potential issues with train service, so we need to make sure other options are available.
  • SS organising technical arrangements

Business as usual with organising this conference.

STANDING ITEMS

SI-0 Tier-1 Manager’s weekly report & Technical Meetings [AD]
Not in attendance.
AD reported that there had been a power glitch overnight and it seems to have affected some services at the Tier-1 and also reports of issues with (RAL) Tier 2 at today’s meeting.
SS said there was the usual test lag, but it seems the issue was fairly short lived and people are getting their services back.

SI-1 ATLAS Weekly Review and Plans [DCos]
Nothing major to report. Just a few glitches here and there and now all resolved.

SI-2 CMS Weekly Review and Plans [DC/KE]
– The power outage overnight had no particular impact on CMS jobs, so that seems fine.
 -There were also a few failures at the weekend, nothing much though and now all resolved.
– Continuing work with Shoveler.
– Working on investigating Rutio issues.

SI-3 LHCb Weekly Review and Plans [AM]

-LHCB DIRAC update happening today
– 3 Tier 1 tickets still remain open.
A suggestion has been made about ticket involving slow deletes, but there are concerns this could make issues worse. Still seems to be ongoing issues with all 3 tickets.
– DB has said there is a need to keep pushing forward with these issues. AM and PC suggested next month is when the focus should intensify as this will be when the new Liaison starts. One of the first major issues for the new person.
People at RAL are currently working on these issues.
SS to also ask at (RAL) Xrootd dev meeting.

SI-4 Operations Meeting Report [SS,PG,PC] –
NTR.

SI-5 LCG Management Board Report of Issues [DB]
PC brought up question of Token Transition.
-OSG-based experiments seem keen on a more accelerated schedule for tokens than in WLCG as a whole. (But, for example DPM sites will not be able to use tokens until they migrate to other SE services.).
-DB and SS agreed there needed to be discussion around this, but perhaps quite a large topic to try and deal with at GridPP48.
-Tokens are a big topic, and will be mentioned in a number of talks, as it affects all LHC Experiments and other projects (like Analysis Facilities).
-SS to put together a few slides on technical situation around this. These could then be used at either Ambleside or a specific technical meeting about the subject.
-SS to make a note to follow up with Alistair and perhaps plan a technical meeting around this.

SI-6 External Contexts (eg NGI/EGI) [PC/JH]

JH submitted a joint IRIS-GridPP document on Friday to the Future of Compute Review being conducted by DCMS.

The panel conducting the review is also approaching specific facilities and infrastructures to ask more detailed and specific questions.
GridPP have also been asked for these responses.
They may want individual inputs from IRIS and GridPP, but it was agreed we can couple as we see appropriate.
Thanks to JH and Davide and Pete for all of the work on this.

JH will soon be announcing the digital asset call now that the DRI money confirmed. (IRIS).
Deadline early/ mid Sept?
Yet to confirm the length of it.
JH and DB have a quick discussion about this at Ambleside.
