Gareth welcomed to the PMB
1. GridPP35
===========
Still negotiating with sponsors. Registration is now live, so far 24 registered, only 4 places in more convenient of the two hotels remain. Sponsorship issues in good shape. Need to work on agenda and invite relevant speakers. Draft agenda being worked on. Expect to be able to discuss the outcome of GridPP5 – will need to work around this item depending on outcome. Need to liaise with Liverpool about welcome and invited talk. Aim for one talk summarising physics outcome from Run 2. We agreed the existing list of non-LHC talks but now need to add DiRAC – PC to contact Lydia. Need to avoid undermining UK-T0 meeting – might be better to make these talks shorter.
Discussed how to cover cloud activities – DC to provide suggestions. Need to cover the CePH pilot at RAL and Tier-2 challenges. Need update on AARC -JENS. How to cover challenge of migrating small Tier-2s to 0.5 FTE – AM and DC to produce a plan. Networks, Tim Chown (end to end performance), IPV6 (High level View Dave – UK implementation Duncan?) and Data defined Networks. Short summary on LHCONE – Pete Clarke. Update on named data networks from ICL. Whole session on networking. PC to update agenda and circulate. Talks from all 3 experiment representatives experience so far in Run 2. Ian Neilson to give security talk – DK to discuss with Ian.
ACTION 570.1 PC to contact Lydia regarding agenda and contributors for GridPP35.
ACTION 570.2 PC to update GridPP35 agenda and circulate.
ACTION 570.3 AM and DC to produce a plan for covering cloud activities and migrating small Teir-2s to 0.5FTE.
ACTION 570.4 DK to discuss with Ian Neilson to give a security talk.
2. GRIDPP36
===========
Pitlochry – expected cost to be less than £12K? Experience shows that this is an excellent venue and has accommodation available which can be difficult to obtain from universities at this stage of year. Have reviewed typical cost of GridPP meeting – typically £10K-£12K for a meeting. Pitlochry comparable with usual university options and cheaper than London. In the absence of a support secretary, if we turn down this option it will be challenging to arrange a university venue over the next few months. Travel is very cheap from London if booked early. Prior experience was that costs were not unreasonably high. No objections from PMB to this venue. Members to provide feedback to Pete by COP Tuesday if the date w/b 4th April 2016.
ACTION 570.5 Members to provide feedback to PC by COP Tuesday if the date w/b 4th April 2016 is suitable for GridPP36.
3. CMS Efficiency
=================
DC will chase this up at the CMS meeting in Lyon. AS noted that June efficiencies were 55% (DC observed it was improving!) – DC will continue chasing efficiency issue.
ACTION 570.6 DC to continue chasing CMS efficiency issue.
4. AOCB
=======
a) Open Compute – DC still investigating.
b) PC asked Tony to give us a heads up regarding any further Cloud compute projects
STANDING ITEMS
SI-0 Report from Development (Cloud) Group
===========================================
DC noted nothing major to report.
SI-1 Dissemination Report
===========================================
No Report
SI-2 ATLAS weekly review & plans
=================================
Packet loss between Glasgow and RAL.
ACTION 57.7 GS packet loss between Glasgow and RAL.
SI-3 CMS weekly review & plans
================================
Nothing to report.
SI-4 LHCb weekly review & plans
================================
Nothing to report.
SI-5 Production Manager’s Report
=================================
DPM workshop in December and WLCG workshop in first week of February. Slow progress with small VOs – few updates. June availability figures now available. See GDB agenda.
Tier-1 Manager (Gareth) Extreme visiting 4th August to investigate router faults. Extended downtimes. Gareth has reported readiness for Run 2. Capacities meeting MoU commitments (except minor discrepancy for LHCb). Bandwidth a little constrained owing to remaining linked on UKLIGHT router.
SI-6 Tier-1 Manager’s Report
=============================
No report.
SI-7 LCG Management Board Report
===========================================
No management report.
REVIEW OF ACTIONS
=================
533.3 DC to draft a preliminary response for any future security incidents where the press might contact GridPP (Tom Whyntie should be briefed on this as well in case he is contacted direct). Two possibilities – If Press contacted before they know anything “Operational Security is taken very seriously by GridPP. All security issues including the handling of any ongoing security incidents are handled by the GridPP security team according to agreed security procedures. I am not at this point aware of this particular issue but I will discuss with the team and more details will be available later.” DB proposed I am not able to comment – rather than not aware.
If we know anything then EGI security team working with EGI communications manager to agree kind of information required and dry run. Done.
567.1 DC to report back on CMS RAL CPU efficiency drop in April & May. Done
568.1 DC to investigate the Open Compute Project and revert to the PMB with information about cost-savings, risks, and capital required. Ongoing.
569.1 PG to put the issue of LHCb tape usage and provisioning onto the PMB agenda before the next quarterly resource meeting; possibly also discuss this at GridPP35. Done
569.2 DC to ensure that any relevant people (eg: LZ etc) are on the email notification list for UKT0 update meetings. Done.
569.3 PG to put item CMS RAL CPU efficiency drop in April & May (567.1) onto the PMB Agenda for two weeks’ time. Ongoing.
569.4 DC to get in touch with Alistair of LZ when he returns to the UK, to ensure LZ join the Tuesday Ops Meeting. Done.
