Notes from Meeting. |
Teir-1 Liaison 20/11/2019
Attendee's RobA Marcello, Jose, Darren, Brian, Raja, Alistair
QUESTION Raja, when was the xrootd reboots done - during the last liaison meeting. There was an elog entry.
ACTION DM : GGUS#144015, orig issue resolved. Create new RT ticket regards optimising processing. Close the orig ticket.
ACTION DM : GGUS#143762. Possible to tailor the queues per VO, however the risk outweighs the gain. We might break something we haven't anticipated i.e. accounting. This ticket to be closed as we aren't going to "resolve". SL6 to be supported up until end of Nov 2020.
ACTION AD : GGUS#143669 not progress
ACTION Raja : GGUS#143323 : Add some statistics to tickets showing improvement (or not!)
GGUS#142350 : Double read issue, no apparent improvement. GGUS#143645 (solved), however ticket listed 3 possible solutions, the working solution(s), has not been identified.
QUESTION Raja, why are some WN's more susceptible that other, no one seems to have an answer. Possibly more jobs running on the node, the more likely something will fail. Failure rate can be as much as 20%.
DIRAC used because of late binding functionality, this seems the be kicking LHCb.
ACTION Raja Further investigation required to differentiate between user and production jobs.
ACTION Marcello to ensure the caches are working on the gateways.
DUNE ran test jobs at RAL, loaded 1500 jobs, we got 10. However, there are not enough DUNE jobs to go around! RAL is processing them correctly.
ACTION Raja : How does DUNE allocate jobs to sites
