IT-protoDUNE coordination meeting 02-11-2022

Attendance

  • Denis PUGNERE (protoDUNE)
  • Elisabetta PENNACCHIO (protoDUNE)
  • Steven Timm (protoDUNE)
  • Jose CASTRO LEON (IT)
  • Elena Gazzarrini (IT)

Minutes and Action items from previous meetings

  • (Steven) Was not there last time, so what is ASDF?
  • (Jose) Services and Discussion forums. Have a look in Indico. 

Coordination News

  • (Jose) Two items:
    • Accelerator sector requested IT to provide infra to run jobs to do FPGA and system design. Need central provisioning. If you want to get onboarded please let us know. 
    • Using EOSPUBLIC upgrade to EOS5 and XrootD5, some experiments did not want upgrade during data taking. Let 
  • (Steven) 14-18th Nov data pipeline running, would be better not then. 
  • (Jose) they will not do it until the end of month/beginning of December. 
  • (Steven) Do we need to upgrade EOS client? We are still using FUSE mount. 
  • (Jose) Will check with them. 
  • (Elisabetta) We are taking data now. End of November is a relatively quiet period, so in principle it should be fine. You said it should be stopped for 5 mins? 
  • (Jose) Yes, almost transparent. NA61 and NA62 were concerned. 

IT Information Update

Round table and action list review

  • (Steven) 
    • Implementing DAQ system and trying to stress the pipeline all the way up to EOS (14-18 Nov). Big activity will be noticeable. 
    • NP04 and NP02 have until now been using the DUNE VOMS server, but the DUNE collaboration is interested in getting a CERN ID to have VOMS hosted on the CERN site. Will submit a request to IAM to get authenticated properly to the DUNE server. 
    • We are trying to access EOSPUBLIC with voms-proxy, but is there an alternative way to authenticate? 
  • (Elisabetta)
    • Taking data now, using FTS and EOSPUBLIC. No issue. No particular requests. 
    • (Jose) Quota is fine?
    • At the moment, yes. Right now, cold box data taking. Next year (April) we have NP04 running and will need to reverify with Steven and Kirby. At the moment, NP02 a lot of raw data is still available on EOS. Once the campaign finishes, we will need to clean up so we might come up with new requests. 
    • (Steven) We rotated test runs but there was a guy at neutrino platform who managed to get a lot of CERN resources. Next time we need to figure out who this guy was. When protoDUNE makes requests it should come from the neutrino platform. 
    • (Elisabetta) Xavi was also setting up all of the egroups for this. 
    • (Jose) If you need more resources, I can interface with CERN.  
    • (Steven) There are dask and storage resources. Denis Clark will contact you soon, I will give your email. 
  • (Dennis) nothing new to report. 

Current Actions

  • About EOSPUBLIC upgrade: check if they need to update the EOS clients. 
  • DUNE security team will be requesting VOMS or IAM at the CERN site. 

New Actions

  • None
