1. Middleware releases and staged rollout

1.1 EMI-1 release status

EMI Update.

1.2 Staged Rollout


Preparing UMD 1.6 scheduled for 26 March: UMD_1.6.0_Contents The contents will be reviewed in the next couple of days.

The following EMI products have already passed the staged rollout and are now in the UMDStore area:

Current in staged rollout from EMI:

There are several products from IGE corresponding to Globus 5.2 release, most of them now in staged rollout. Due to the change of Globus library packaging, there where some EMI components that where broken, the new versions of those products should be released in this week EMI update, namely DPM 1.8.3 and Storm 1.8.3. The new IGE Globus release will only be done in UMD together with the new EMI updated products.

There is 1 EA that has offered to do the Verification and Staged Rollout of LFC 1.8.2 with Oracle backend, currently the SW provisioning is in progress.

The SW provisioning workflow is beeing tested with IGE Debian packages in preparation of EMI2.

2. Operational Issues

2.1 Testbeds for EMI WN

For LHC VOs: CERN keeps the pre-production testbed up-to-date to the newest release of the worker nodes, and it is accessible by the LHC experiments to test their code.

Question: Are there NGIs deploying a testbed with EMI WN?

The issues related to WNs (and UIs) should be listed - for example in a wiki page - in order to identify the bugs that can be blocking for an upgrade gLite3.x -> EMI, and track the release of the patches.

2.2 OPS VO Membership

Recently there were few requests (triggered by the glexec monitoring tickets)to replace some ops VO members because they were no more part of the NGIs' staff. I would encourage NGIs to replace their ops members as soon as they are not working on this task anymore, if possible:

  1. Currently only 2 members per NGI are allowed in ops, it would be important to have both of them active members of the NGI's staff. If the main SAM admin is unavailable(e.g. he needs to wait few days for a new certificate), there is the need for an immediate backup.
  2. It is also important to have in ops only who strictly needs the membership.

2.3 Temporary area for job execution

Topic already discussed last year in the operations meeting: Here, for example.

First draft proposal: The worker node environment should contain the variable: $TMPDIR, that points to the file system where the jobs are supposed to find the required disk space.
