GridPP PMB Minutes 239 - 11th December 2006
===========================================

1. Tier-1 Status Review
========================
AS provided the following report:
1) CPU delivery: Our load test is underway (7 days) with no major issues
found. This equipment is on track to be in production 1st week in
January.
2) Disk Servers (delivery 1). Supplier had difficulty developing a process
for updating the drive firmware planned for last week. However this is
now expected to be carried out Tuesday/Wednesday after which we expect
their load test to commence. Provided all goes according to plan this
will lead to this equipment being available before Friday 19th January.
However this does involve our load tests running over the Christmas
period where there is some risk of disruption.
3) Disk servers (delivery 2). Supplier have now updated the drive firmware
on these servers but have not yet arranged a delivery date with us. We
expect delivery will be late this week or early next week after which
they must run their 7 day load test followed by our 28 day load test.
This equipment is on track to reach production at the start of
February.
4) Servers. Problems with the supplier configuration recommendations have
been resolved. Load testing looks very encouraging. The worst 7 servers
have been under load test for 4 days with no drive ejection (eject
rates are variable but we would have expected several by now - prior to
the updates). We expect to start load testing most of the remaining
servers by Tuesday. 9 PPD disk servers have been in operation with the
new drive firmware for 7 days with no drive ejects - however only one
has been under high load - the others are either CASTOR or dCache
production. We believe that by the 15th December we will be in a
position to say if the problem has been resolved - we are reasonably
hopeful that it has been. We are planning on deploying these servers
into production W/B 2nd January.
The PMB noted that by next Monday's meeting a clearer picture of status
will have emerged.
STANDING ITEMS
==============
SI-1 News Items and Meeting Dates
----------------------------------
SP reported two news items last week: DN as User Board Chair and the gLite
Brokering Meeting. The meeting had not been too productive, but
developments were expected. Alex has been in touch with SL regarding
financial modelling, which is in early discussions. This week SB sent a
draft text on the new version of the GLUE schema. SP will try to make it
a news item for Science Grid This Week. Any ideas for news items from the
PMB are welcome before Christmas. Neasan O'Neill has put together new
images on the GridPP website from the Collaboration Meeting and from
PPARC. More images are welcome. These are for Press use etc. JG noted
that he could send some Tier-1 photos but would need to find out about
copyright status.
SI-2 Production Manager's Report
---------------------------------
It was noted that JC was on holiday.
SI-3 LCG Management Board Report
---------------------------------
JG reported that last week's discussion had involved Tier-1 milestones for
2007, taking experiment requirements into account. The task of distilling
the experiment requirements into T-1 deliverables was delegated to the LCG
Experiment Co-ordination Meeting which normally meets weekly to discuss
short-term requirements but will discuss the long-term situation also.
The GDB also met last week. The most interesting discussion was regarding
the running of pilot jobs which run payloads from multiple users and
issues relating to trust and security. No strong consensus had been
reached but proposals were being circulated within the GDB.
SI-4 Documentation Officer's Report
------------------------------------
SB reported that he was working on updates to the User Guide, including
proofreading and a revision to the GLUE schema appendix. The other authors
are also updating their text, with a view to producing a new version
before the end of the year.
REVIEW OF ACTIONS
=================
234.1 PC was continuing to inquire on the use of Grid papers in the RAE.
Ongoing.
235.1 Information had now been received from CMS. RJ was still awaiting
BaBar information which he will forward on.
236.3 Information regarding funding for a CMS Grid workshop at Bristol in
January '07 was ongoing.
236.4 DN to summarise and circulate the CMS model as a basis for
discussion. Ongoing.
236.5 RJ will summarise and circulate the ATLAS model as a basis for
discussion. Ongoing.
236.6 GP will summarise and circulate the LHCb model as a basis for
discussion. Ongoing.
237.1 TD, in conjunction with AS and JG, will define the Tier-1 manager
role and add to the PMB page. Ongoing.
237.2 RM, DB and Dave Colling had begun to rationalise workload management
deliverables, but this requires discussion with EGEE staff to get answers
to some outstanding questions. Item closed, but deliverables not yet
defined.
237.3 SL had now circulated a document showing the breakdown by experiment
for the Tier-2 resources for 2007. Item closed, but GP needs to do some
work on this.
237.4 TD and SL (with input from DB) still to write a 1 page proposal for
a site readiness review in March/April 2007. Ongoing.
237.5 There was some discussion regarding the block booking of rooms in
the hostel for the WLCG collaboration workshop. It was noted that the
hostel require TC to call them after 4pm, which he has been unable to do.
It was noted that something needs done about this quickly, it was
suggested to hand-over the task to Mary Elizabeth. JG sent TC an email to
this effect during the meeting. The PMB noted that if a block booking is
not made, it will result in steep hotel bills. [After the meeting TC
confirmed that a block booking has been made. SB is now verifying that
the bookings are still required.]
237.6 SB had now provided a first draft news item on the GLUE schema
revision. Item closed.
238.1 DB had now circulated an email summary to the PMB of the GridPP2+
outcome. Item closed.
238.2 JC to organise a 'forward-look' at the connectivity of the Tier-2
sites - it was noted that JC was still on holiday. Ongoing.
238.3 PC had now drafted a GridPP response statement to connection
requests but this was not yet circulated. Item closed.
AOCB
====
GP noted that he had contacted RM regarding costs for the LHCb software
course in January. These had increased from the original estimate due to
higher accommodation costs being observed now that participants are
actually registering. The PMB agreed the increased cost.
