VDT Office Hours 28 September 2006

Attendees

TclGlobus 1.4.0

TclGlobus 1.4.0 is coming along well. They are adopting the Gnu Public License and looking into some performance issues. They'll get a new version to the VDT in a week or two.

VDT 1.4.0

A few bugs are being fixed in VDT 1.3.11, and it is being rebranded as VDT 1.4.0, and it will be the basis for OSG 0.5.1.

Different versions of Generic Information Providers

The generic information providers used by the OSG are different from the ones used by LCG. Shaowen and Anand say that the generic information providers are supposed to be per-grid, and that there are three main differences: our scripts read the grid3-user-vo-map.txt file, our version doesn't make the same expectations about what is in the environment, and there is a gums provider. Alain asked if these differences could be be merged into the LCG versions by merely having conditionals (if "OSG", then... else ...). Anands thinks that they can, though it would require more coordination with LCG.

Verifying BDII

David Meyers asked about verifying the BDII's output. The GROW folks have a web page that shows the results of validating all BDII/GRIS output in the OSG. David would like a script he can run locally, and the GROW folks will consider it.

Leigh pointed out that there are two kinds of verification. First, we can verify that the data conforms to the Glue schema, and second, we can verify that the data is reasonable. Currently we are not doing the latter. It's a hard problem, and one that we should address.
