- Mike enabled pilot roles for both ATLAS and LHCb. He will also work on a parser which digests torque logs and gives the accounting figures in HEP-SPEC2006.
- Dug has been tracking down problems and discovering more about the LCG-CEs failure modes than he ever wanted to know (double job running from comms problems all down the line between ganga, wms, CE and batch system).
- Stuart has been optimising the cleanup of shared disk areas, which were cramping our style by sending the main nfs server into serious i/o wait for 20 hours in the day.
- Sam has installed a small test xrootd server - hopefully I will start running some analysis jobs against it soon to test it out.
- We reviewed our fairshares in advance of STEP09 to make sure each group was getting their due. We dropped most of our opportunistic VOs down to 1%.
- I discovered a jolly wheeze in Maui to use QOS to help bind the three different ATLAS fairshares into one QOS unit, with its own fairshare. This gives ATLAS sub-groups a fairshare advantage if the total ATLAS usage is under the total ATLAS target. Goes like this:
GROUPCFG[atlas] FSTARGET=10 MAXPROC=2000,2000 QDEF=atlasDurham:
GROUPCFG[atlasprd] FSTARGET=21 MAXPROC=2000,2000 QDEF=atlas
GROUPCFG[atlaspil] FSTARGET=11 MAXPROC=2000,2000 QDEF=atlas
- Running well, but we decided not to implement the ATLAS pilot role (no intention to really support ATLAS analysis - they don't have the disk) and the LHCb pilot role is optional.
- Did the HEP-SPEC2006 benchmark on their nodes and got 67.82 for their Xeon L5430s (2.66GHz).
- To ward off less efficient user jobs we deleted ATLAS AOD - should see them only doing production for now.
- APEL publishing problem fixed.
- Steve plans to replace the ancient gLite 3.0 CE with a spiffy new gLite 3.1 one.
