GridPP PMB Minutes 189 - 10 October 2005
=========================================
Present: Tony Doyle, Stephen Burke, Robin Middleton, Steve Lloyd, Roger
Jones & Dave Britton. Sarah Pearce (Skype)
Apologies: Dave Newbold, Tony Cass, John Gordon and Jeremy Coles.
1. JPhysG Final
===============
TD was happy to report that JPhysG had been finalised. He wished to thank
SP for all her work on this with additional effort from SL & PC on the
final editorial board. SP said the final question from the publishers was
to ask how the collaboration members should be referred to in the authors'
list. There were 3 options:
a) GridPP Collaboration with a web address to the author list;
b) GridPP Collaboration with all the authors listed;
c) the members who edited.
The board agreed that they would prefer to have all the authors listed on
the paper [option b)]. See
http://www.gridpp.ac.uk/papers/jphysg/
2. Quarterly reports due by the end of this week
================================================
DB reported that he had a message from JC stating that reports would be
delayed as some staff members were at HEPIX this week. RM said he had
received 2 out of 6 reports. It was his intention however, to have all
reports completed before EGEE in Pisa later this month. SL said he had
still to receive his reports. RJ said he had received all reports except
BABAR & CMS. TD said Tier-1 was still outstanding as Andrew Sansum had
been busy with the upcoming procurement.
STANDING ITEMS
==============
SI-1 ALL: to provide any news items and meeting dates for the web page to SP.
SP thanked SL for his report on Grid Ireland which has now been posted.
She said that Jens Jensen was preparing a draft on the International
Global Trust Federation which was launched at GGF last week. This will
be released this week by CCLRC and SP will also post it on the web.
SP said a news item on '100TB of storage at the Tier 2s' from Greig Cowan
was being prepared.
SI-2 Production Manager's weekly report of issues.
TD discussed JC's report in his absence as he was attending the GDB with JG.
1) The VO Box discussion will be taken to the GDB this week. We captured
input from GridPP sites and Steve Traylen presented it at the
operations workshop. The outcome was that operations would produce two
documents - questions surrounding constraints of the VO services and
use of the VO box (Steve Traylen created and circulated a document) and
a presentation for the GDB (Jeff Templon - NIKHEF). In the presentation
draft circulated on Friday it was observed that the system
administrator views have been toned down. The statement is that all
sites will deploy VO boxes because of the experiment "needs", however
in our UK discussions it was felt that some sites could not support VO
boxes (due to local policies) and that VOs that require VO Boxes would
not necessarily receive the support they want - ALICE in particular is
unlikely to get a separate VO Box at any UK site other than Birmingham
and RAL. The GDB is supposed to reach a decision on this but may not
have sufficient input or consensus to do it.
- TD said that the current position is that VO boxes would not be deployed
at Tier-2s until the Tier-1 says it is a manageable process (this had
not happened so far). The questionnaires are to be sent to the VOs so
that they can give details of exactly what they are requesting. The
results should then be sent to the sites so they can judge whether they
can provide the VO boxes. However, it isn't clear to what extent the GDB
meeting this week will pre-empt the decision.
2) For the GDB the Tier-1 has been asked to provide a plan covering the
next 6-9 months in detail. This is to include resources available at
stages throughout the period. There appear to be extra complications in
doing this given the delays in the response from the OC. The assumption
stated at the last PMB meeting was that the funding would be available.
The delays may already be impacting the tendering process.
- TD confirmed that the OC had given their approval though PPARC would
have to move the funding across the financial years. DB said he would
have to check with DK on information received on a 31,000 tape purchase
to see what had been included in his figures as this may now have to be
adjusted.
With the regard to the time factor, TD said (as noted in the Tier-1/A
Board summary) a 4 month lead-in is needed for hardware to arrive at RAL,
2 months installation and a further 3 months to commission the disks.
Andrew Sansum subsequently provided a more detailed timeline that will be
used by the Hardware Advisory Group overseeing the procurement
3) JC had a constructive meeting at Liverpool on Tuesday 4th. This
provided useful background information to include in the Q3 2005
NorthGrid quarterly report about problems the site have experienced and
use of resources for PPARC science over the last year - generally
locally submitted LHCb and ATLAS work. JC along with Phil Allport, Mike
Houlden, Themis Bowcock, Michael George and Paul Trepka, agreed a 3
week timeline for getting Liverpool active in GridPP followed by
increased contact for setting up an SRM (most likely dCache-SRM). Greig
Cowan will visit the site in the near future to get the process
started.
4) RAL Tier-1 is now fully participating in SC3 Service Phase. LHCb and
CMS are active. A VO box is set up for ALICE and they are deploying
services on it shortly. However ALICE still has no disk allocation.
(They request 2GB per job slot which could mean up to 2 or 3 TB
needed). LHCb use of dCache-tape pools was for the first time and they
uncovered two minor problems which have been fixed. A request is
expected shortly from ATLAS for a VO box. CMS have seen peak transfer
rates at the 800Mb/s level.
- SB said that VOs have to specify how much disk storage they want (as
referred via the questionnaires). It was noted that UKLight is fully
functional again.
5) The deployment team has started gathering Service Challenge 4 planning
data for the Tier-2s. Updates will be tracked via an SC4 wiki page
which shows in which month the various services will be deployed at
each site:
http://wiki.gridpp.ac.uk/wiki/Service_Challenge_4_Site_Status.
An SRM deployment planning document is expected shortly from the storage
group. The document was released on Tuesday -
http://www.gridpp.ac.uk/deployment/admin/tier2-support-plan.pdf
The Ten Easy Network Questions was discussed at the UKI monthly operations
meeting on Wednesday (http://agenda.cern.ch/fullAgenda.php?ida=a055907)
and considered useful by those who attended. This meeting successfully
used VRVS for the first time.
- TD said Ten Easy Network Questions should be made more visible and
e.g. sites should put their answers on the wiki page.
6) RAL eScience have allocated a person to start work on the "black box"
to translate xml output from GGUS into the Footprints schema and
vice-versa. When in operation this will solve many of the currently
experienced ticket exchange and update problems. Discussions at the
last ROC managers meetings about regional VOs only being locally
supported makes the area of user support more complicated than
discussed at a previous PMB. The ROC is working on a web-form that
allows automatic forwarding of user submitted queries to the relevant
queue in Footprints. LHC VO users should be directed to "VO
name"[log in to unmask] This directs the ticket directly to an
experiment support unit as does a relevant selection on the GGUS
web-form: https://gus.fzk.de/pages/ticket.php.
- TD ask SB to update links to review the high-level links to "Grid
Support" since this focussed on Operation Centres rather than the GGUS
pages which are used for regional VO support across EGEE (ACTION)

GridPP PMB Minutes 187 - 26th September 2005
============================================
Present: Dave Britton, Stephen Burke, Tony Cass, Jeremy Coles, John
Gordon, Dave Kelsey, Robin Middleton, Dave Newbold, Sarah Pearce
Apologies: Tony Doyle, Steve Lloyd
1. Tier1A Stakeholders Board
============================
There had still been no response from the Oversight Committee to our
papers on the next procurement, nor any minutes from the last meeting. We
need to know about resources in 2006 to report to LCG by the end of
September. The Board also raised the issue of the relative cost of disk
and tape. The Tier1 will prepare a response.
2. All Hands Meeting 2005
=========================
This was generally agreed to be useful for GridPP with a number of
presentations and posters and a good demonstration on the PPARC stand.
Next year we might consider fewer people attending; perhaps only those
presenting plus sufficient to man the stand.
The fraction of papers accepted had been disappointing. JG will
investigate whether there has been an analysis of the programme.
Note
184.2: DN to report on GridPP All Hands abstracts
