Sites meeting
Manchester—more files are transfer now, we are not sure why.
RAL user area—want to manage with sam4users won’t release
Ernesto Kemp—Unicamp
There is a proposal for several Brazilian institutions to access the supercomputing center
Getting several science institutions to make a proposal mostly for dune
Production
Fairly large section of jobs seems to be failing with read buffer errors
Nothing specific to RAL
Can be one of several things—
Either stream interrupted due to network problems
Or if we spend a very long amount of time on one event, longer than the timeout, the xrootd connection dies..
Have lengthened the timeout.
Can also happen in cases where you don’t hit the timeout, it will close the connection if it doesn’t get a reply within 60s.
Will try to lengthen that timeout as well.
In recovery pass we read in the whole file instead of streaming.
Update on perfsonar matrix—no update, J. Hays will try to get one by next week.
Anything on the CRIC
A. McNab There will be a dune dedicated instance sometime within the week.
Site renaming—tagging with DUNE_GLIDEINSite
Now that production is a bit less will start requesting.
Ken shows site distribution plot from recent production to date.
