Changes to Minutes of 22.11.2005 (document)
The changes proposed are approved. Minutes of Last Meeting (documents) The minutes are approved. Matters Arising L. Robertson received a draft of the Report of the LHCC Comprehensive Review. He had various comments and corrections which he will discuss this evening (6 December) with E.Tsesmelis. |

Action List Review ( list
of actions, document
) |
|||||||
Done. The final version of the Task Forces functions is attached (link).It explains also how ATLAS and CMS
will report on their non-EGEE grid sites:
December 2005
Done.
Done. J.Shiers distributed a summary (link)
of the feedback received: From J.Shiers’ email: - CNAF would like to attempt transfers at the full
nominal rate (but outside the formal SC3 rerun, which as such uses the SC3
target of 150MB/s as max per site) - The level of participation of NDGF is not clear at
this time - All other sites have confirmed the target rate.
Done. In the
current proposal there is no usage of tapes, as part for the SC3 re-run. The MB
decided that the tests to tape at Tier1 sites should be re-instated in the
SC3 re-run early in the year, no later than end February. It is felt
important to check that the complete dataflow (from CERN disk to network to
storage on tapes at the Tier-1) is working, even if these tests are not done
using the latest version of the mass storage systems (Castor 1 or 2, dCache).
Delaying the first tests to April risks that problems will be discovered too
late to be rectified for SC4. Action: 28 Feb 06 – The disk-tape tests should be
re-instated in the SC3 throughput re-run at the beginning of the year, to be
completed by the end of February. Such tests should verify that a steady
satisfactory transfer rate can be reached and that past problems have been
solved.
On the way. LHCb is
added to this action as it plans use VO Boxes during SC4. Not all experiments
have provided both VO Boxes questionnaires (operations and security).
On the way. Answer from J.Shiers
to the MB mailing list:
On the
way. Action: 6 Dec 2005: CNAF should send milestones for
Tier1-Tier1 and Tier1-Tier2 operations.
Done.
On the way.
Done. The presentation of the plan is part
of this meeting.
On the way: H.Renshall will produce the proposal. |

Milestones and Plans Issues |
|||||||
Network Milestones and Service Availability ( more information ) Concerning the milestones:
Email from D.Foster:
OK, so I quote from my previous mail: "So for the 3 T1's I think we can foresee Fermilab, SARA and IN2P3 but also TRIUMF, BNL and CNAF will not be far behind, if at all by the end of this year. ASGC has already 2.5G to netherlight (sharing the 10G transport to CERN via SURFNET) and it is not completely clear how that will evolve."
I think this is clear the list of 6 T1's, with the 3 before the end of this year.
Only CNAF uses GEANT2/GARR.
The situation is changing all the time as priorities for connectivity are adjusted by the NREN's and GEANT. I will ask for a GEANT specific update.
Action: To complete definition of milestone OPN-2
D.Foster should find information about the GEANT2 plans and send it to the
MB. DB Project Milestones ( document, transparencies )
The presentation covered the following points: -
Replication tests -
Proposed Tier 1 Hardware Setup -
Proposed 2006 Setup Schedule -
Production Service Setup Status -
Production Software Status -
Open Issues The 2006 Setup Schedule document
has been discussed with the Tier1 sites and by the end of January all
hardware agreed should be available and tested.
There will be a Tier-1 readiness workshop (Feb 2006) with: - reports from Tier-0 and Tier-1 sites about database and squid cache installation - report from ATLAS, CMS and LHCb about conditions implementation for main subdetectors. Open Issues: •
Squid support at Tier 1 sites: •
Applications server support at
Tier 0 •
Oracle streams production setup
for the Tier 0 site: •
Oracle licenses and support for
Tier1 sites must be clarified before the production period starts. The MB approved the proposed plan. Procurement and Resource Scheduling Issues ( more information ) Attached there are: the summary of the procurement plans and the collection of emails that discuss this issue. The MB agreed that the tables in the MoU should match what is planned by the sites. And if needed they should be changed accordingly as soon as possible. Action: 12 Dec 05 - Sites should urgently send updates to the capacity tables of the MoU. For 2006 the nominal capacity can be made available by July 2006, but for the following years the required capacity should be available by April each year. At presently not all capacity available is used, but: - such capacity is needed in order to provide realistic performance tests in the service challenges - the risks in delaying hardware acquisitions too much are high and they need to be reduced - the sites need to continue
to gain experience in to 2006 in order to be ready to provide full hardware
capacity in 2007-08. These issues should be explained to the funding agencies. Action: 19 Dec 05 - L.Robertson should explain
the Tier-1 milestones and the procurement issues at next Oversight Board
meeting in December. |

Summary of New Actions |

Action: 28 Feb 06 – The disk-tape tests
should be re-instated in the SC3 throughput re-run at the beginning of the
year, to be completed by the end of February. Such tests should verify that a
steady satisfactory transfer rate can be reached and that past problems have
been solved. Action: 20 Dec 05 - To complete definition of
milestone OPN-2 D.Foster should find information about the GEANT2 plans and
send it to the MB. Action: 12 Dec 05 - Sites should send updates to the capacity tables of the MoU. Action: 19 Dec 05 - L.Robertson should explain
the Tier-1 milestones and the procurement issues at next Oversight Board
meeting in December. The full Action List, current and past items, will be in this wiki page before next MB meeting. |
