1. Contextualization

We need some text from Sebastian with regard to Contextualization.  Tony will follow up.

2. Image catalogue

Romain has the prototype working at CERN based on Owen's work. Romain has taken out some of the complexity of the initial prototype (automation for Tier-2s). Owen comments that the simpler version may be a better point to consider the truck of the development rather then his initial straw man.

Owen is waiting for people to come back from Holiday. He needs 2 weeks travel notice for DESY policy. Week of the September 27th is possible, something in the week of the October 4th more realistic.

Owen considers the most important thing at the moment is secured signed messages passed between catalogs. 

3. Signalling from the site to the virtual machine.

There is desire for some information about the virtual machine inserted into /etc/machine/features. The requested features are:

- HS06 rating
- Expected end time of VM

Tony has presented this the WLCG Management Board, and is expected to present it again on September 28. Tony asked the group if there are additions to this list.

Martin pointed out that he has heard some interest in other benchmarks. There is no reason why not, however tony commented that he would expect site managers to want to have a limited number of benchmarks to insert in that file.

Owen asked if there should be information about the trust of the image in the file. Tony commented that he thinks that the focus is on static information.

Martin asked if requiring the SPEC benchmark was an issue (it's cheap but not free). Ian Gable pointed out that this is already a WLCG requirement for sites. Tony mentioned that in the general HEPiX context it is not a requirement and that he doesn't want the group to take a position on it.

4. Any other business

RAL is evaluating CERNVM FS. There is some work going on with a security audit, not clear what state the audit is in.

Owen asked if the work with CVMFS invalidates some of the work of the catalogue. Tony commented that it certainly will reduce the number of VM that must be tracked but the distribution is still the same.


5. Next meeting september the 27th, 14:00 UTC

- Understand when Owen is coming to CERN.
- Presentation on Romain and Owen about how they plan to advance the image catalog.
- More from Ian Collier on CERNFS
