Going back over our to do list for the week..
Reprocessing status
Had a meeting on Wednesday via EVO. Tom reports that there is a prototype job that starts from digi files. This prototype breaks runs into chunks and does not yet merge. That is on the to do list. Tom plans to look into the skimmer's merge utility for this purpose. Tom was wondering what merging tool is currently used in the pipeline. Will use xrootd for merging. Warren has had troubles with AFS, so after Tom checks on the failure rate with xrootd, Warren may do the same. Tom, Tony, and Karen discussed bookkeeping issues and what to store in Oracle. Next up is to create the tables and the interface.
Skimmer
Tom reported on the current status. There are a variety of reported skimmer problems. David Chamont is just leaving for vacation until early August but did offer some work-arounds for the current issues.
1. Julie reports a crash with 100 merit ntuples, which Tom can reproduce with the command line skimmer v6r1 and v6r0p1. Julie had reported seeing memory usage in the 3GB zone, while Tom recalls nothing over 400 MB.
2. Patrick Smith using v6r1 on a rhel4 machine reported failures. Tom was successful using the skimmer on rh9. This problem seems to disappear when using the v6r0p1 version of the skimmer.
3. Simona had trouble extracting recon events. Tom has not had an opportunity to look at that too deeply.
The web interface for the skimmer continues to use skimmer v5. Tony reported that he can see from the logs that there are many users. Richard asked about the failure rate. There have been no reported problems, but Tony will go back to the logs to see if there are unreported problems.
Python Distribution
Jim had sent out a request for reports of python distribution problems. There was no response, so for now this issue is tabled. Eric W asked what plans there are to move to python 2.6. Jim said it is under consideration. Navid requests that we remain at python 2.5.1 until Red Hat catches up.
SCons
After our meeting on Wednesday, Navid reports that he has checked in a series of SConsript files for some GR packages into CVS. He can now build and run some test applications on Linux and Windows. For those that may like to try this o Navid will teach Emmanuel how to proceed with the updates, and Emmanuel will take that over from here on out. This allows Navid to focus on the new RM and MRScons (name TBD). Navid has started to talk to Tony concerning issues about the new RM. Concerning the need to scope out the issue with JO files - Navid has decided to start the environment variable conversion and while doing so, take a look at the JO files in the affected packages.
