Discussion¶
- AI (Diego): Continue to build and scitokens packages for EL8. Contact Jason Patton for software help.
- AI (Edgar): Build scitokens-issuer for EL8; Derek to merge pull request and make a new release.
- AI (Edgar): Build osg-gridftp for EL8 since osg-xrootd-standalone is blocked by osg-configure.
Support Update¶
-
JLab (BrianL): Walked the admin through setting up an Origin container. Topology registration is done; Derek will work on CVMFS. JLab will have their own CVMFS endpoint at jlab.opensciencegrid.org, with per-experiment directories.
- Takeaway: we really need to improve the container so that it's easier to test before Topology registration. Our current policy is to require registration before installing the software; we will revisit the policy.
-
Vanderbilt (BrianL): Pilots being killed by the CE after 8 hours (shortly after a proxy renewal). Investigating with the HTCondor team.
-
Edgar: Working on giving UC-Irvine a hosted CE on SLATE. Also planning to set up a hosted CE for EXPANSE, but needs to do it without SLATE.
- Martin Kandes has complained about the install instructions for the worker node client. Brian L would like additional information; for a hosted CE, the site admin shouldn't have to install worker node client.
-
Marco Mambelli: Planning to release glideinWMS 3.6.3; there is a known issue with a missing dependency in the spec file, which will be fixed in the next release.
- glideinWMS 3.7.1-rc1 has been released.
-
Tim T: Built Bosco tarballs for EL8 per Ops request for Clemson.

OSG Investigations Team¶
- (No-progress) CVMFS Singularity Sync is going to start using singularity to create the containers. Working on testing, see github discussion:
- https://github.com/opensciencegrid/cvmfs-singularity-sync/issues/245
- More feedback from interested parties and they seem to be happy. Will provide feedback when Derek is back from vacation.
- StashCP Go implementation is ongoing.
- Proactive site monitoring is progressing nicely. Presented last week at Ops, good feedback!
- UNL's production cache is 5.0.1, with SciTokens enabled.
Discussion¶
Tim T discovered that the HTCondor Campus Factory subpackage is broken; was wondering what it was, and if it was still in use, or required for BOSCO.
Derek (original author) said it was a way for campuses to set up a mini-Glidein Factory. bosco_cluster has callouts to it but they can be removed with minimal effort.
