2. Main Achievements

During the reporting period the so called “New SW Release Workflow” (NSRW) has been implemented in the RT queue “sw-rel”, and the notification tests have been performed.

Early Adopter teams: For gLite 3.2 series most of the components are covered with at 1 or more teams, the sole exception presently are the MyProxy, dCache and VOMS_Oracle. Recent addition of EA to test LFC_Oracle from a WLCG T1. In a collective response from ARC sites, several EA teams have volunteered for ARC components. (Mitigation of issue 3 of QR2)

The report template is now used for all staged rollout tests, and uploaded into the document server: Search “staged rollout” in , an example:

The total number of Early Adopter teams is now 40, it includes one more team from a WLCG T1, and a Canadian team, besides all newcomers for ARC.

MS407 could finally be finished giving a complete picture of integration of resources into the EGI production environment.

A draft procedure was produced together with JRA1 on how to integrate new probes into SAM Nagios. Input could also be collected from the ARC probe developer side.

A dedicated meeting was called to clear up the requirements around the urgently needed new features for UNICORE integration in GOCDB. Those could be successfully be re-defined (and thereby mitigating the biggest issue for integration of different resources and middleware stacks of QR2).

3. Issues and Mitigation

Issue Description Mitigation Description
gLite 3.2 components without EA: MyProxy, dCache and VOMS_Oracle Myproxy has already a confirmed volunteer. dCache, discussions ongoing with developers to publicize to the sites deploying dcache, and thus have EA volunteers. VOMS_Oracle, follow a similar approach as was done for LFC_Oracle.
The test of the full chain of SW release is delayed Most of the implementation is completed, and the test is expected early in the next reporting period
UNICORE integration is hampered A new taskforce has been build to enhance and increase communication between the different partners involved and to organize a set of dedicated meetings
Bringing all ARC sites onto the same level A survey is organized among the NGIs involved to better coordinate the switch to the new ARC probes in their regional Nagioses and to collect their plans on how to publish the accounting records

4. Plans for the next period

Objective: to have at least 2 EA teams per component. This is needed if:

  • One team is unavailable (backup).
  • Increase the probability to catch any problems or issues.
  • Increase the heterogeneity of the testing, and eventually different deployment scenarios.

Test the full chain of the SW release Workflow. Opening the GGUS ticket by the Technology Provider, creation of the RT ticket in the “sw-rel” queue for QC Verification, Staged Rollout, and release to production. The staged rollout will be done in the RT queue “staged-rollout” with a child ticket from the one in the “sw-rel” queue.

The end of the period will coincide with the release date of EMI 1.0.

Main plans for interoperations are:

  • Solve the issues above or redefine them at least
  • Bring some relevant procedures from draft into acceptable shape
  • Collect more requirements especially about accounting (already started)
  • Survey together with IGE on best timelines for Globus integration
