Graph the FTS Deployment

The FTS deployment is of course made up of channels between sites in the EGEE/LCG grid. This plot shows all the channels as queried from the BDII as lines connecting the sites. The grouping of nodes by colours represents all the channels managed by a single FTS instance.

Again it is another plot that is almost impossible to use.

Graphing Glue

I've been playing with GraphViz and HyperGraph to draw out the relationships between the objects in the GLUE schema. The results are interesting but especially for the complicated sites, e.g. CERN, GRIF, RAL,... they are hard to read. There are massive png's, vrml and svg formats. Also the html pages load a dynamic applet of the data. I'll request that they are worked into gstat which is the natural place for them to live once I have improved them. Warning: Some of the png images are huge and will most likely crash your browser. The image here is RAL-LCG2. The orange blob top right is the FTS.

Combined SLC4 and SL4 CE.

As part of the WN working group efforts I've been finishing of a vandalised CE which is now part of the CERN_PPS site. It is two node cluster both of which are WNs. One is also a gatekeeper publishing GlueCE, VOViews and CESEBind objects, the other is publishing two GlueCluster and GlueSubClusters objects. ... To cut a long story short I have a single gatekeeper node which can matched to for either SL4 or SLC4 and the jobs route through to the correct node at the back. It is exactly the same for any GlueSubCluster attribute such as memory for instance. Tomorrow we try and thrash how to get the final steps of this into a release.... It is quite possibly not going to be pretty, keeping things backwards compatible may just not be possible or desirable. details.
