1. Comments on June 2010 Tier-2 Reliability
============================================
Various site explanations had been circulated by PG. He advised that QMUL had downtime due to
a power outage to install equipment; Birmingham had various issues to do with upgrade to their
HPC cluster, also local cluster issues and other miscellaneous issues; Bristol had problems with
their HPC cluster and timeouts; there had been issues at Manchester. DB noted that individual
issues were understood, but was ther a larger overall issue here? PG advised that there was no
one common problem affecting all sites. JG asked if tickets were being received? PG noted they
should be, but he could check. DC advised that there were also staff issues at Bristol. PG noted
this was a factor elsewhere as well. DB asked if a high-level summary of tickets was dealt with at
dTeam? PG noted only the ones that had been outstanding for a long time. DB asked for
confirmation that there was no procedure that we had missed? JG advised that the HS06 number
was not being generally recorded. PG noted that correct numbers were being published but were
not being picked up, there was a bug in the system.
2. GridPP Poster/Leaflet
=========================
SP reported that Neasan O'Neill had iterated with DB. NO had looked for images and needed to
update the GridPP fliers etc. A quote had been received from APO who did work for GridTalk - this
was 1500Euro to design a leaflet, poster, and other artwork. If we ordered this now, it would be
ready for All Hands and EGI. SP noted that purchasing items for community events was
acceptable to STFC. DB asked if there were any preview images that SP could circulate? SP noted
that they would use the images that already existed on the GridPP site. DB asked for comments. It
was agreed that the quote seemed reasonable, we did need some material available, so the design
work should be ordered as discussed. SP would follow this up. TD reminded that the RTM could
also be used.
3. CERN@School
===============
DB noted that a document had been circulated. SL advised that the document was aimed at
GridPP and was not for wider consumption - we had asked for use cases. The proposal was to
begin by using a cluster then expand later into a VO. DB asked if a web portal was required? SL
advised that something already existed at present. We would be a portal that they would operate.
It was agreed to wait until JC returned, and the issue could be discussed at Ambleside. DB noted
that we needed to contribute text for circulation regarding the GridPP interface etc - what was the
timeframe? It was agreed to continue positively with the contact meantime - comments from
dTeam would be welcome. PG noted he would bring up the issue at the meeting tomorrow. DB
asked SP to put this item on the Agenda for Ambleside.
395.1 SP to put 'CERN@School' on the PMB Agenda for Ambleside.
4. Week's Notes
================
EGI Technical Forum: DB noted that Early Bird Registration was still available, and UK people
should register as soon as possible. It was understood that hotels may be in short supply.
Security incident: Was there any further info. on this? There had been slow responses from
Durham and JET and there were also communication issues.
Ambleside: Were speakers finalised? DB needed names asap. It was thought a good idea to
arrange a minibus to meet the London Euston train at Windermere at 11:39 am on the Tuesday,
rather than using taxis. SS confirmed that arrangements were more or less finalised for the
Collaboration Meeting. It was noted there would be a joint PMB/DB on the Tuesday morning. In
relation to DB evolution, it was felt that this might need to close but it should be discussed - a joint
meeting might be better. The DB tended to repeat items already discussed during the week.
Funding - FY10 spend plan: DB reported that he had contacted Tony Medland re the planning
expenditure for the remainder of this financial year. We had two plans for capital and resource
spend but STFC still did not know the funding position. It was agreed that we should proceed as
planned and if we needed to spend anything on the Tier-1 we could check with TM on a case-by-
case basis (this related to the remainder of GridPP3). DB would request further info. for
Ambleside so that he could pass on up-to-date information to the community. PG reminded that
there were contractual/renewal issues affecting staff.
STANDING ITEMS
==============
SI-1 Tier-1 Manager's Report
-----------------------------
AS was not present.
SI-2 ATLAS weekly review & plans
---------------------------------
RJ was not present.
SI-3 CMS weekly review & plans
-------------------------------
DC reported that everything was relatively quiet - there was an incident about ten days ago in
relation to Alice jobs, which had been dealt with. DC advised that Bristol should be designated a
Tier-3 site. DB asked why this couldn't be done more or less immediately? DC noted this was
difficult to do in terms of perception and history. PG reminded that no manpower was allocated
there in GridPP4, and he was due to have a meeting soon regarding remote support - things were
unlikely to improve there. DC thought it could function as a small Tier-3 and that we should re-
name it. DB asked about the process and timescale within CMS for doing this? DC advised not at
present, probably September would be preferable. DC reported that UK sites were performing
well generally at present and were helping to get results for iCHEP.
SI-4 LHCb weekly review & plans
--------------------------------
GP was not present, but had sent a report:
1)Moved to using 3GB queues at RAL. This is going to be a long-term request and arises out of the
high nu (#interactions/bunch crossing) data we expect to take in the future.
2)Continuing challenges for LHCb applications which are being worked on. The running
conditions are significantly noisier than expected at time of software design.
3) RAL LHCb-LFC went down during "AT-RISK" last week. Some LHCb users had problems
submitting jobs, but did not affect already submitted/running jobs. Problem of why this downtime
affected users is under investigation by LHCb.
SI-5 Production Manager's Report
---------------------------------
PG reported on behalf of JC, noting that he had circulated a few emails re status. Regarding EGI
middleware, there were UK sites on the list - Oxford had applied to be an official test for the Cream
CE, Glasgow would be on the official list for testing DPM. There was a question re the Quarterly
Reports and inconsistency of MoUs being used? SL noted that we should use the 2009 MoU. DB
noted that CERN regarded the 2010 ones as the correct benchmark but due to funding issues at
present, we would continue to use the 2009 figures. PG advised that sites needed to buy kit as
soon as possible. PG noted that dTeam had been asked to comment on the 'NGS to NGI' document
- they had noted that this focussed on NGS needs only, and it was unclear as to how an NGI would
be formed. DB advised that another document: 'GridPP to NGI' was being prepared, describing the
move to NGI from the GridPP perspective.
SI-6 LCG Management Board Report
---------------------------------
DB reported that there had been an MB meeting on 13th July, but nothing particular to report.
There had been an item on the 2010 pledge installations but they had only asked about the Tier-0
and Tier-1 - which were all fully installed on time. JG reported an item on data-access - they were
expecting demonstrators to do more in October at the GDB, including milestones. A group had
been set up to review them. There had been a discussion on xrootd and whole-node reservation -
experiment input was required. There had also been an item on cloud-based image model.
SI-7 Dissemination Report
--------------------------
SP reported that NO had put up a news item on the Edinburgh Shared Services Centre, and he was
working with Andrew on a new version of the news page, which would be going live shortly.
AOB

There was no other business.
REVIEW OF ACTIONS
=================
366.8 AS to confirm that the Tier-1 proposes to use Tape-
based storage in the period 2011 - 2015. Ongoing.
384.1 AS to provide a plan for how to deal with the ADS
Service, and bring back to the PMB. AS would circulate a summary. Ongoing.
384.6 TD/JC to take the lead on the 'GridPP to NGI' document that addresses the forward-moving
technical and other issues from a GridPP perspective - a skeleton outline would be circulated by JC
based on the NGS paper.
PG noted this was on the Agenda of the d-Team meeting for comment. PG to send any inputs to JC
& TD. Ongoing.
394.1 ALL: concrete suggestions for topics were required re virtualisation, multicores etc (to
DB). This session needs to dovetail with LHC Data Management, which is a separate issue.
Ongoing.
394.2 SP to contact STFC and invite a speaker to come and give a talk for the KE/EI session.
Ongoing.
394.3 AS/SP to provide a spend plan for the remainder of FY10 financial year - this would be
