Upgrading to ATLAS Release 14

I am currently upgrading my tests to ATLAS Release 14 starting with User Analysis. All sites without Release 14, which requires SL4, will fail the test. All sites will probably fail while I get the bugs out on my side! For the time being the other tests will use Release 13 (even if 14 is installed).

New SE Tests

There are now some new tests of the UK SEs. These run every hour (for the moment) and attempt to copy a (2.8MB) file to an SE (lcg-cr), check it is there (lcg-lr), read it back (lcg-cp), delete it (lcg-del) and check it is no longer there (lcg-lr). The log files from these operations are available by clicking on the test result. You can see that the results are not 100% correlated with the SAM test results (which is why I did this). See:

Auto RB

On the basis of my RB tests I now define an 'Auto RB' which is one of the 'Good' RBs or failing that one of the 'Fair' ones. This RB is then used for my ATLAS tests. This should avoid having to manually switch RBs every time the RAL ones go down.

Major Disruption

There was major disruption over the last couple of days after a raid array died and various things had to be recovered from backup. Everything should be running again now but there is some history missing between 13-19 Dec. This could be recovered but is probably not worth it. The system is 'at risk' from now till 3 Jan (no 24x7 here!). Merry Christmas and a Happy New Year to all who use my test results.

ATLAS Tests now all use release 13.0.30

I have finally managed to create some 13.0.30 AOD and upload it to (most) UK SEs. All the tests are now using 13.0.30. QMUL, UCL_CCC, Lancaster and Edinburgh are not getting the analysis job at the moment as I could not make the replica at these sites.

Problems at RAL

All the RAL RBs seem to be 'stuck' and the lfc is not reachable. I have switched to the ScotGrid RB to try and get the ATLAS tests running again.

Many Changes

So finally things have stabilized. The ATLAS and RB tests are running properly again using a database (rather than text files) to improve reliability. The php scripts that provided the summaries have been replaced by static pages to stop the webserver errors. In addition there are now tests of the UK top level BDIIs: http://hepwww.ph.qmul.ac.uk/~lloyd/gridpp/bdiitest.html All the tests are summarised on one page (accessible from the GridPP home page): http://hepwww.ph.qmul.ac.uk/~lloyd/gridpp/ukgrid.html Plots of SAM performance are also available:
