Dual phase TPC [Viacheslav Galymov]

  • geometry implemented in GDML, rotated
  • "wires" are actually traces on a silicon board
  • [Brian Rebel] some algorithms will ask for "the" single collection plane, of which we have two
  • what is the treatment for the inter-plane electric field? apparently not
  • [Erica Snider] optical simulation will be special in the gas

Conclusions

  • long term actions:
    • review the code distinguishing or making requirements on "the" collection plane
    • support a zero inter-plane field in LArVoxelReadout

Update on CI test suite deployment [Vito Di Benedetto]

  • testing MicroBooNE with Jenkins
  • replacing GENIE flux files with histograms
  • tests are running about three times slower in Jenkins than they do in uboonegpvm0x

Conclusions

  • issues with non-reproducibility of reconstruction need to be investigated and solved

LArSoft project status report [Erica Snider]

  • releasing v04_30_00
  • new ifdhc should be supported by OSX as well
  • new IFDH requires a new dependency
  • [Herbert Greenlee] what OSX users should do? (CVMFS is problematic) A: use UPD
  • [Herbert Greenlee] can it be distributed in scisoft? A: it does not abide to requirements (it's basically a system package)
  • [Herbert Greenlee] is there a way to convince Redmine to ignore blank differences? A: not sure
  • [Jonathan Paley] it would be profitable to have a consistent indentation
  • moving meeting time

Conclusions

  • proposing to move the Coordination Meeting on Tuesday 9 am "off week" (example: on November 23rd, 2015)

Architecture review status report [Gianluca Petrillo]

  • temperature should be moved now
  • [Erica Snider] see if LArProperties is still worth a service
  • [Brian Rebel] temperature in LArProperties is entangling dependencies
  • [Herbert Greenlee] people need ample warning; are there ways to mitigate the blow? A: basically, no
  • [Erica Snider] are changes scriptable? A: [Jonathan] partially
  • [Jonathan Paley] urges to merge as soon as possible, as the branches go stale quickly

Conclusions

  • start advertising the changes in LArSoft mailing list
  • plan to merge in 2-3 weeks

DUNE MCC 5.0 preparations

Note: Dorota Stefan and Robert Sulej could not make it. Tingjun Yang showed a bit of their work.

[Tingjun Yang]

  • request to hold the release while Robert Sulej finishes his work

[Gleb Sinev]

  • importing supernova neutrino generator into LArSoft
  • [Tingjun Yang] ROOT file will need to be in larsoft_data, LArSoft wiki explains how

[Mike Wallbank]

  • [Gianluca Petrillo] documentation? A: will do

Conclusion

  • LArSoft release will be delayed until Wednesday 5 pm; Tingjun Yang will communicate the feature branches when ready
  • Lynn Garren and Gleb Sinev will interact to set the location of the ROOT file required by the new generator

Other business

Request to integrate part of the core service immediately [Jonathan Paley]

Jonathan Paley requests the part of the core service review in branch feature/jpaley_dunePedDev_2015_11_16 of lardata to be merged in this release
Reorganization of the directory structure is ongoing.
Jonathan accepts to comply to whatever organization is imposed, as long as it goes in this week release.

Mainteinance work on two issues [Brian Rebel]

  • issue #10937: DUNE TPC might need to write their own auxiliary detector sorter
  • issue #10936: [missed discussion?]
