GridPP PMB Minutes 245 - 5th February 2007
===========================================
Present: Tony Doyle, Sarah Pearce, Roger Jones, Stephen Burke, David Britton,

Jeremy Coles, Glenn Patrick, Andrew Sansum, Suzanne Scott (Minutes)
Apologies: John Gordon, Peter Clarke
1. Preparations for the OC
===========================
TD noted that all OC documents had been finalised by Friday morning (2nd
Feb). Several issues remained:
1. an update of the 'active' user statistics - previously there were 20
'active' users, now there are 80 broken down by VO. In the metrics on
the project map, DB checked the figures. TD noted that previously the
user metrics had been broken down into 'active users' and 'really
active users'; an 'active user' being defined by submission of more
than 10 jobs per month. 231 users are registered in the Grid map file
at the Tier-1 and are not in dteam. DB will report on the user stats.
2. With regard to the Outturn Report, it was agreed not to circulate to
LCG until after the OC meeting, assuming that PPARC accept the figures.
3. DK reported that he had been in contact with BT security but had
received no response. He will follow-up and report back.
There were no other outstanding points. SL, DB, RM, and TD will be at the
OC meeting in London on Thursday and will report-back next week.
[Note: the meeting was cancelled on Thursday due to snow]
2. STANDING ITEMS
==================
SI.1 Dissemination Officer's Report
------------------------------------
SP reported on a news item on Friday relating to the WISDOM Data
Challenge. Newspapers in India, Grid Today, and Medical News had all
carried information. SB had sent information relating to the gLite User
Guide. SP requested some information on the WLCG meeting from JC. SP
confirmed she had emailed Hannah Cumming at TOTAL but had received no
reply. SP will follow this up. DN was to send SP information on the CMS
workshop. SP had already received info on the ATLAS workshop last
Thursday/Friday from RJ. RJ and SL reported that the ATLAS workshop had
been successful with good user feedback. SP noted an article on the GLUE
Schema had run in iSGTW. Regarding the EGEE User Forum, SP had received
three abstracts and would chase-up individuals if any others were known.
TD noted that there was also a deadline for the All Hands Meeting. Was
there to be a report from each Tier-2 for EGEE Manchester User Forum? JC
will contact the Tier-2 co-ordinators. SP noted that the other deadline
was OGF and asked whether we intended to submit something to this? TD
noted that it would not be possible in the remaining timescale, but an
invited talk may be negotiated? SP will follow-up. SP will also send out
an All Hands and EGEE user guide roundup to UKHEPGRID.
SI.2 Tier-1 Manager's Report
-----------------------------
AS provided the following report:
Hardware:
1) First Supplier delivery
Integration into dCache is complete. Integration into CASTOR of 11 servers
is almost complete. Servers will be available by Wednesday. Further
servers to replace the loaned PPD equipment will be available to the
CASTOR team by late in the week.
2) Supplier Two Delivery (I)
Acceptance testing continues and is on track to complete on time. We have
no significant problems at this stage that will delay acceptance in mid
February.
3) Supplier Two Delivery (II)
Acceptance tests will start by Wednesday and will complete by the end of
February.
4) Tape Purchase: 350TB of media has been ordered - delivery 3 weeks time
5) Tape drive purchase: 3 drives have been ordered - delivery in about 3
weeks time
6) Tape drive servers: Probably ordered.
Service:
January reliability in SAM was 80% which was below our WLCG target of 88%.
This was primarily caused by problems at the BDII which is scheduled for
replication this week.
[note: now scheduled for next Tuesday]
We have now been asked for our timetable to provide SL4 for CMS. There are
a number of issues in doing this on the short (8 week) schedule that CMS
require. We will hold a planning meeting later this week to finalise a
plan for RAL.
AS noted concern regarding the release of software/middleware for SL4 - a
realistic schedule needed to be worked out for deployment for CMS
initially. An achievable plan would hopefully be devised this week.
Staff:
It was noted that Alex Holt had started as a member of the Fabric team.
SI.3 Production Manager's Report
---------------------------------
JC provided the following report:
1) There is a GDB meeting this week
(http://indico.cern.ch/conferenceDisplay.py?confId=8469) and there will
be a vote to select a new chair person. The PMB registered their
unanimous support for John Gordon as candidate for Chair.
[Note: JG was susequently elected Chair of the GDB]
2) CMS have developed a plan to load test sites during 2007 (details are
here:
http://indico.cern.ch/getFile.py/access?contribId=1&sessionId=0&resId=0&materialId=slides&confId=11667).
At a meeting this morning it was agreed that GridPP will participate
from next week, subject to the readiness of CASTOR at RAL. The Tier-2
sites will (in the first instance) be Bristol, RAL-PPD and a selection
of sites in the London Tier-2.
3) SL's tests continue to "challenge" sites.
http://hepwww.ph.qmul.ac.uk/~lloyd/atlas/atest.php. We did see some
improvement last week but also a lot of BDII/RB related problems. The
BDII instability at RAL is also very evident in the SAM results from
last week for most UKI sites. The Tier-1 is planning to deploy a second
top-level BDII this week which should improve the situation. The
storage group is looking at SE tests which by-pass the information
system so that we can get a truer picture of the SE status across sites
(though the grid based tests will still be the most important in terms
of VO access and usability).
4) The RAL Tier-1 PPS site is now setup as a candidate site in the GOCDB.
Most elements are now in place and we are seeking more specific
feedback about the level of resources needed to be "useful" as a PPS
site and also plans for connecting PPS sites with production WNs and
SEs.
5) Cambridge Ontology and TOTAL E&P have been setup on the GridPP VOMS
(Ontology has been there for some time now) so we now need to help the
VO managers add new users and request sites to support the VOs. VOs
setup under VOMS at Manchester can be seen here:
https://voms.gridpp.ac.uk:8443/vomses/
SI.4 LCG Management Board Report
---------------------------------
It was noted that JG was at an EGEE ROC Managers' Meeting.
SI.5 Documentation Officer's Report
------------------------------------
SB noted that the web pages need to be checked to see if they require to
be updated. It was asked whether we can put in a request to point to the
UI configuration information in a reasonable way? [Some answers are here:
http://www.gridpp.ac.uk/deployment/users/faq.html#chooserb]. There was a
question about recommendations for resource brokers: could this be
discussed at the DTeam. It was to be suggested as a point for discussion
tomorrow.
REVIEW OF ACTIONS
=================
236.4 DN to summarise and circulate the CMS model as a basis for
discussion. This was done during the meeting. Item closed.
236.6 GP to summarise and circulate the LHCb model as a basis for
discussion. GP would now focus on this as two models were now available.
Ongoing.
ACTIONS AS AT 05.02.07
======================
236.6 GP to summarise and circulate the LHCb model as a basis for discussion.
245.1 DB to report on the user statistics.
245.2 JC to forward information on WLCG meeting to SP.
245.3 JC to contact the Tier-2 co-ordinators regarding reports for the
Manchester EGEE User Forum.
245.4 SP to send out an All Hands and EGEE user guide roundup to UKHEPGRID.
AOCB
====
The issue of the Site Readiness Review was raised, and it was noted that
some dates had now been set up. TD noted two items:
1. At the last OC the issue of visits to sites had been discussed and it
was felt useful if GridPP members could go to sites and inform them
about GridPP and how it can be used. The question was how best to do
this? It was noted that the issue of site readiness, and presenting
the Grid to users, were two separate things. The local Tier-2
co-ordinators could probably help, but it was felt not to be the
optimum approach, to try and do the two things simultaneously.
2. TD noted that it had been agreed that Management lead would organise
the weeks to use for visits. The London dates had been chosen: w/c 16
April and 30, 31 May - this gave 7 days to cover 5 sites. Although 7
days were set aside for the London review, this was intended to give
flexibility in setting dates for each site. Depending on the timetable
for each review, it may be possible to combine two on a single day.
The SouthGrid dates were 9, 13, 14 March. TD advised that he was
working on the NorthGrid dates. RJ would advise constraints.
Regarding ScotGrid, it had been hoped to use the week of the GridPP
meeting to review Edinburgh and Glasgow, but only one day was
available: the Friday. This was yet to be finalised.
RM enquired whether a central email would be circulated to inform site
admin about the Review? DB, SL, TD and RM would liaise regarding this
during the OC meeting. It was noted that it would be preferable if an
agreed format for the days could be devised, although individual
site/visitor constraints may prohibit this.
It was noted that TD would be absent at next week's PMB and it was agreed
that JG would chair.
The meeting closed at 2.00 pm.
