Week of 080407

Open Actions from last week:

Daily CCRC'08 Call details

To join the call, at 15.00 CET Tuesday to Friday inclusive (usually in CERN bat 28-R-006), do one of the following:

  1. Dial +41227676000 (Main) and enter access code 0119168, or
  2. To have the system call you, click here

Monday:

See the weekly joint operations meeting minutes

Additional Material: There will be LCG OPN tests Wednesday 9 April from 15.00 to 19.00 CET. The plan of the test is here: https://twiki.cern.ch/twiki/bin/view/LHCOPN/BackupTest RAL will be unreachable for 15-20 minutes between 16:45 and 17:15 PIC will be unreachable for 15-20 minutes between 17:15 and 17:45

The goal of the maintenance is to verify that all the backup solutions work as expected. The T1s with a backup link should be up all the time, but at the moment we cannot guarantee that it will be the case and there may be outages at any time for any Tier1.

Tuesday:

elog review: Nothing new

Experiments round table:

ATLAS (from K.Bos): we have started our Functional Test (FT) around 3:30 pm today. We had decided to run at a rate as if we were taking data with the detector at 200 HZ for 10 hours per day. In that case we run at roughly 40% of the maximally needed throughput because we have 24 hours to export the data we produce in 10. This will be the mode we will be running in May also unless we are taking cosmic ray data in which case the rate is determined by the TDAQ. We intend to stop the production on Friday morning and remove the left-over FT subscriptions on Sunday night. So we leave the system 2.5 days to transfer all the data. On Monday morning we will analyze the results.

CMS: the recent SAM srm test failures due to information disappearing from the bdii has been fixed.

LHCb: Preparing for infrastructure testing to start on 18 April. The slow throughput recently seen on the CERN to CNAF traffic has been corrected (not known what happened). The LHCb LFC is now replicated to NL-T1 and PIC is scheduled to start next week.

Sites round table: RAL would like information on Tier 1 resource requirements for the May CCRC from CMS and ALICE as soon as possible. NL-T1 confirmed they expect new (2007 pledges) hardware resources to start being published during the last 2 weeks of May.
