Dear site admins
You will probably be aware that for the last 2 months Steve Lloyd has
been running a series of test jobs against GridPP sites. There are three
types as explained here:
http://hepwww.ph.qmul.ac.uk/~lloyd/atlas/atest.php?action=info. You'll
note that only the analysis job is ATLAS specific so the results are
pretty indicative of a general user's view.
The deployment team via the Tier-2 coordinators and storage group have
been addressing problems uncovered with many of your sites. However, it
seems that there are many reasons the tests may fail including when a
tested site is full of ATLAS production jobs. Nevertheless one might
expect to see a little more stability than is observed. Please take a
look at this wiki page which now shows the historical results for each
site since January: http://www.gridpp.ac.uk/wiki/SL_ATLAS_tests. The
first plot is the combination of all sites and shows how chaotic the
situation is to a user!
Please feel free to edit the wiki with comments for your site explaining
some of the variations if you can. We will revisit these results at the
next UKI monthly support meeting on March 14th.
Kind regards,
Jeremy
