Release and project report [Saba Sehrish]
- release with Geant4 10.3 and GENIE 2.14 in preparation
- Data Science @HEP workshop taking place in May, physicists are welcome to join
- a number of improvements have been introduced in time
- python interface hiding remote file access behing a POSIX-like interface
- result validation phase on worker node rather than in the final location
- added ability to user
xrootd to read ROOT files in "streaming" mode
- useful when the files are not read in full
- a UPS override is added to allow use of off-site SLF6 systems with newer kernel
- it is possible to specify in
project.py configuration any executable using the same command line interface as lar
lar.py is such an executable, able to process ROOT trees and configurable via FHiCL- some ROOT macros have provided, including a class
RootAnalyze to analyse a ROOT tree with custom code
- [Robert Kutschke] Ray Culbertson (mu2e) has a "system" to map the available offsite resources
- [Alex Himmel] there are ways to do this with SCD tools (propoosed follow up off-meeting)
- some of the scripts are candidate for inclusion in
larbatch (from ubutil)
- pending adoption of python FHiCL parser into FHiCL UPS product
- as future, planned improvement,
Profiling LArTest with Open|Speedshop [Soon Yung Jun]
- Open|Speedshop profiler is used by Geant4 team to profile Geant4
- it may take up to a few hours to install
- it provides different "experiments", that is sampling models and information extraction
- [Giuseppe Cerati] are there features to test vectorisation performance? [A] yes
- [Herbert Greenlee] is Open|Speedshop going to be illustrated in the workshop? [A] The specific tools to be illustrated haven't been decided yet
- [Gianluca Petrillo] is OSX supported? [A] Yes
- [Gianluca Petrillo] is this distributed via UPS? [A] we don't even know whether it's technically possible
C.I. system updates [Vito Di Benedetto]
- an upgrade to the C.I. web interface will be deployed on April 26 (tomorrow)
- [Herbert Greenlee] which is the monitored memory? [A] it's the resident memory (RSS)
Off-plane charge recovery in LArG4 [Gianluca Petrillo]
- a new optional feature has been added to
LArG4 to lead charge to the wire plane when its projection is outside of it
- this is a geometric approach that does not try to be rigorous
- improvements can be scheduled on demand
Any Other Business
- [Alex Radovic] warnings from external packages are upgraded to errors
- [Lynn Garren] we typically handle this via wrapping headers
Conclusions
- Alex Radovic will contact LArSoft or art mailing list for a plan
