  • LCG 48 almost ready (delayed by problems with SEAL 1.9.0).

Marco Ca. raised the issue of binaries compiled with SSE2 instructions. Nick said that we do not know yet how much we loose by not letting run the jobs on nodes that do not have the instructions, but Andrei is checking the monitoring issues to sort it out.

Round Table

Marco Cl.
Working to prepare the migration from XmlDDDB to CondDB, he wrote a script that parses the XML files and finds all the files connected to a starting file. In this way he found few unused files (mainly in Velo) and discovered that the ECAL test beam set of files is not complete. The Visualization XML files and DTDs will not go into the DB. He managed to reduce the number of CondDB folders from 3000 to 400.
Marco Ca. suggests to wait until XmlDDDB is forzen for DC06, than we can branch and start modifying the head.
Asked about the plans for the inclusion of links to MCHits in DSTs. Marco Ca. will investigate the increase of size to see if we remain under the TDR limit.
