1. Minutes and
Matters Arising (minutes) |
|
1.1 Feedback to
the Minutes of Previous Meeting Two changes
(J.Shiers, M.Delfino) were proposed and are highlighted in blue in the new
version of the minutes. If no further
feedback is received before next meeting, then the minutes will be considered
as approved. 1.2 Section Numbers in the Minutes M.Delfino suggested
adding numbers for sections and subsections in the MB minutes, in order to
ease references to specific sentences: This is being done, starting with
these minutes. |

2. Action List Review (list

Done. All VO Boxes questionnaires are at the
page: VoBoxesInfo wiki page
LHCb done. ATLAS done, see link: ATLAS
Tier1DataFlow wiki page ALICE and CMS to do. Done. See all the contact here: LCG PlanningSC4Contacts
wiki page
Not done by all (URGENT). Done. All sites have responded. Will
participate: FZK, IN2P3, PIC, TRIUMF, SARA, BNL, DESY (Tier-2). Most sites prefer to do the test re-run
during the week starting the 30 January.

SC3 re-run results and tape test plans · Summary of the SC3 throughput tests · Plans of the tape tests · The sites that cannot do the SC3 tape tests now
should send (now) the plans of their tape tests (for May at the latest) . |

3.1 Progress of the SC3 Re-run The re-run was much easier than last years and the right set-up
and targets were reached/exceeded rather quickly (a couple of sites a day).
The running of the sites is not unattended and still needs people closely
following the re-run on the sites and monitoring the status. During last week the daily average transfer rate was in the range
750-950 MB/s. This is very close to
the 1 GB/s target, and is also limited by the current network switch
configuration (1.2 GB/s). It was
pointed out that the network data rates measured at the file server level
(Lemon) were slightly higher – see following graphic.
Decision: The MB agreed that the 1 GB/s milestone for the
SC3 re-run can be considered achieved and to proceed with the tape tests.
The weekly meeting, on Monday at 1600, is very useful and it will
include a summary log of all interventions on all sites, in order to share
experience and solutions. 3.2 Participation to the SC3 Tape
Tests Sites that will participate to the tape
tests next week: FZK, IN2P3, PIC, TRIUMF, DESY, SARA, BNL. |

4. SC4 Planning |
|
4.1 Progress of the SC4 Planning F.Donno is drafting the plan will discuss early versions of it
with all parties involved (experiments, projects and developers now, sites a
bit later). A draft will be available to the MB by end January. She is also
contacting the sites for the site-specific services (SRM, FTS, etc). At the meeting the sites asked to know which installations have to
be performed to each site (and when). A proposal will be part of the SC4
planning and will be derived from the experiments “simplified”
models. This is an important goal of the Mumbai workshop. 4.2 Mumbai workshop Each session should mention the goals and the decisions that will
have to be taken at the workshop. And the presentations should cover the
issues on which a decision is expected. The workshop’s agenda is in the GDB agendas list.
4.3 Experiments dataflow and processing models for Tier-1 sites LHCB: the document for Tier 1 data flow and processing is
available since a few weeks. ATLAS: sent the document after the MB
meeting, and was also distributed to the MB list (ATLAS
Tier1DataFlow wiki page).
