Review of Action Items (tasks)

Status of the subtasks of TASK:7143 .

Notes: TASK:7139
Daniele: The installation of Cream at CNAF will be suspended in case the decision is made to close the current pilot.
Antonio: we changed the way we calculate effort: the actual effort is now calculated as:
declared effort * percent complete
This is done in order to count non completed tasks (canceled, suspended) where an amount of work was however spent

Status and results of the pilot service (by VOs and sites)

Phase1 has no much more to say, so we close it and we start phase2

Phase2 will be focused on ICE WMS

The objective is to enable CMS users to submit continuously at a rate of 10Kjob/day over 5 weeks

The proposed layout for the pilot is

  • 2 WMSs: CNAF and (FZK or SCAI)
  • 1 UI CNAF: cert-ui-01.cnaf.infn.it
  • 1 VOBOX(if needed): FZK
  • 4 CREAM CE: FZK (Angela Poschlad), Padova (Sara Bertocco), Bari (Giacinto Donvito), CNAF (Daniele Cesini): SCAI (Klare Cassirer?)
    The CREAM CEs will access production batch systems

Requirements for the software to be deployed in the pilot:

  1. CVS tag defined and yum repository (at CNAF) available
  2. SW documented in patches in state >= "With provider"
  3. SW accompanied by a "certification of deployability" delivered by SA3 Italy (Alessio Gianelle)


- updates of the SW at sites, if needed, will be applied by SA1 personnel on demand of the developers - patches "approved" by the pilot will be set to "ready for certification"

Description of the patches to be expected (provided off-line by Massimo):

  1. new version of ICE to install over a WMS with PATCH:1841
  2. new version of yaim-wms for possible modifications in configuration
  3. a patch of CREAM/CEMon/BLAH (rpms glite-ce* to be installed on CREAM CE)
  4. a patch of yaim-cream-ce
  5. a patch of CREAM-CLI

Patches in c/d/e/ could be released earlier to the standard certification track to fix possible issues in the CREAM now in production

Decision about termination/extension of the pilot

Phase1 is terminated. Next steps for phase2:

  • waiting for the software to be ready
  • Antonio will post an update to the pilot wiki with the new planning for phase 2
  • Antonio will open a new general task on Savannah to replace TASK:7143
  • Antonio will register the new sites in the PPS activity management system
  • Open subtasks of TASK:7143 will be either closed or attached to the new general task by Antonio
