          From: Southwest and NORTH
          To: CERN and France


          Report from SouthWest::

          • Cern has some pps nodes under sam but monday 8 may be disappeared

          Report from NORTH:
          • Problems Encountered during shift
            • Two times the COD Dashboard was unavailable, tuesday morning and thursday morning.
          • Information for the new COD team *
            • Last weeks handover log mentioned the following: GGUS:43130 has to be extended by the reason of SD (until 12/15/08 -Gstat ), but this action was not possible to be done. The ticket has expired and it is still on the Dashboard.
              This is reported as a technical problem of the dashboard.
            • Last week we were able to update this ticket again.

            In order to make easier the life of VOs that want to run either 32b application or 64b one, we would like to make sure that every french site is correctly publishing the GlueHostArchitecturePlatformType attribute of their lcg-CE GlueSubCluster.

            According to the link http://goc.grid.sinica.edu.tw/gocwiki/How_to_publish_my_machine_architecture, the value is obtained by taking the result of "uname -m" command launched on the worker node (that is, the OS bits capability)

            We are however wondering whether that value has to be adapted or not to the effective Glite-WN version (i686 or x86_64). In particular, if your WN OS is x86_64 and your Glite-WN version is i686, the job environment is set to i686. In such a case, do we really have to publish x86_64 as explained in the above link ? Isn t it a bit error-prone for the VOs ?

          • Germany Switzerland

            Job list match problems at DESY reported by user. Traced back to Top-level BDII. Switched back to a host running an older version. Same effect observed at FZK as well. Details are logged in GGUS:44201 [Might be presently assigned to the wrong support unit]

            An example for a problematic jdl file:

            <verbatim> VirtualOrganisation = "dteam"; Executable = "/bin/env"; StdError = "stderr.txt"; StdOutput = "stdout.txt"; OutputSandbox = { "stdout.txt", "stderr.txt" }; Requirements = Member("srm-dteam.cern.ch", other.GlueCESEBindGroupSEUniqueID) ; </verbatim>
