## OSG Software Team

- EL9 repo status?
- Glidein dir cleanup status?
- Thoughts on how we can reduce Hosted CE IPv4 usage?
- EL9 repo status
- AI (Mat): Finish announcement email
- AI (Matt): Review PR for migration script

- Glidein dir cleanup status: temporarily disabled due to holding up Glidein startup
at a site with a large number of dirs to clean up on a shared filesystem.
Todd T, Matt, and Mat had a brainstorming discussion, for which Todd will write up a design.

- AI (Mat): Create new VMU disk images so we can run VMU tests again.
- AI (Mat): Build XRootD 5.7.2
- AI (Mat): Review OSG 24 upgrade instructions PRs

- AI (Matt): Remaining OSG 24 image builds:
- docker-xcache: Mat to review PR
- docker-compute-entrypoint: requires a new osg-ce build, though hosted CEs should
already be using the version of osg-ce from main-testing or upcoming-testing.
Matt should ask hosted CE operations if they are running the new version

- AI (Matt): VMU tests on ARM; CHTC has an ARM machine that is restricted to running jobs
from BatLab and CHTC staff; CHTC operations will review the policy.

### Discussion

None this week
- Thoughts on how we can reduce Hosted CE IPv4 usage?
Need to discuss with the HTCondor development team if unique IPv4 addresses are necessary;
Tim thinks yes, for reverse DNS, but Mat thinks reverse DNS isn't used anymore

Tim suggests running each Hosted CE on a different port but Brian says that would be verfy
painful to manage and would essentially lock CEs to specific nodes.

Brian will investigate IngressRouteTCP.


### Support Update

None this week
- SURF (Mat): LIGO site using an xcache-based cache; they got a new cert and need a LIGO
test file to test with because their cache does not support the OSG VO.

- IceCube (Mat): condor_gpu_discovery not discovering Intel GPUs. Mat will discuss with
the HTCondor dev team.
