Description

Weekly operations meeting for sites doing DUNE computing

DUNE computing ops meeting

 

6/28/2021

 

Tickets —SURFSARA (GGUS 151908). The test jobs work production jobs run but don’t finish.

QMUL (151364) haven’t made progress as yet

CERN 151401—no recent progress

Will discuss at cern / it protodune meeting

 

 

NP02 running

No news

Working on DAQ infrastructure—coldbox will be in EHN1.

 

NP04 —no news

 

 

Production news

Nothing out of the ordinary

Still haven’t heard anything from UNICAMP

Some weirdness at Nebraska also

 

NERSC — are we done?

Not yet—some are taking much longer and we don’t know why

 

Regular stuff—is FTS doing the right thing? We think yes

 

Discussion of data tiers.  Reco-recalibrated tier

 

Data management ops

Ticket over the weekend.. many thousands of small files getting written to tape

Default dune file family is SFA now.

 

In production we control, should be putting in files on SFA or not

For users, have to watch

 

 

Discussions project.py is putting garbagoose in the metadata and we have to deal with it sometime.

Need to set a meeting with J. Hendry and co.

 

Site report

GridPP

Everything broadly OK

 

Fermilab—persistent DCache remains almost full

DUNE allocation temporarily lower at BNL due to STAR

Will DUNE have access to Perlmutter GPU’s at the beginning?  Yes

 

 

CC-IN2P3
