Review of minutes from the last HDGeant4 meeting
We looked at the minutes from the meeting on January 26
There were no significant comments.
FAQ of the Fortnight
Mark led us through the FAQ entry, How do I authenticate to GitHub from
the command line?
The pro's and con's of https vs. ssh were discussed.
Transition from SWIF to SWIF2
Alex led us through his wiki page
describing the changes to come. He has converted most of our production
scripts to operate with SWIF2. We thanked him for putting the page
together. People who need to convert their private scripts to make the
transition should consult his page.
Analysis Launches on the OSG
Sean described work on doing analysis launches on the OSG. See his
the details. The effort leverages the use of the REST files from 2017
that Richard has staged at UConn, using CVMFS to access the data
(StashCache). A successful trial run has been completed. There are
several aspects that need development but having this avenue for
computing open up for regular use will be a significant step up. Sean
also mentioned the idea of uploading the output ROOT trees on
StashCache, simplifying access to those data collaboration-wide.
Curtis is getting a couple of petabytes of disk space that can host data
for this effort. We also discussed the possibility of JLab providing
space served from the DTN which is already in production as an XROOTD
Outlook for LINUX in WLCG
Richard brought our attention to a policy taking shape for the LHC grid
on choice of Linux distributions. See the message he forwarded to some
of us here
They would like to be able to run on RedHat Enterprise, CentOS 7 and 9
(but not 8), and community developed CentOS-style distributions like
Rock and Alma. Jobs on all such systems would use containers to avoid
differences in the distributions.
Review of recent issues and pull requests
We looked at three issues posted by Naomi
1. Crashes with minimal DSelector upon writing output trees, probably
memory leak gluex root analysis issue #156
2. ReactionFilter plugin crashes on rhel8 with DTreeInterface::Fill
error halld_recon issue #613
3. crash with version set 5.3.0 hdgeant4 issue #204
