Announcements¶

(Derek) SIUE - Discovered bug in gratia probe, fixed locally and submitted upstream: https://github.com/opensciencegrid/gratia-probe/pull/107
BrianL:
- We are currently only sending LIGO jobs to Georgia Tech to avoid having OSG (and other VO) jobs run on LIGO pilots.
Marian:
- Continuing to debug JLab submissions at Georgia Tech.
- Lamar (CLAS12) does not have any pilots or show any HTCondor activity.
- Finish setting up ICTS; it is registered in Topology so only the factory config needs to be updated.
Mat: Lancium not seeing enough jobs again; Brian will investigate further.

StashCP go client is working and tested, and being tested by Christina now. Need to talk to Mats on packaging and releasing. (will follow up). No news from Christina,
Design document is done and is being distributed for xrootd monitoring collector NG (next gen). Shoveler is working and lightly tested. Now on to the collector.
XRootD TCP plugin is ready for packaging. Derek will follow up with software team on who to hand that off to.
Discussions of xrootd-multiuser support for checksumming on-the-fly. After a discussion, the checksum-on-the-fly funcationality will be ported to xrootd-multiuser. Copied largely from xrootd-hdfs. This does mean that out-of-order writes will not be supported.
More partners are asking about scitokens-cpp, and compatibility. Expect some updates.
- Maybe we have been doing tokens wrong? Use the typ rather than ver.
(Stalled, but need to get back to it) XRootD accounting information (from Frank):
- May need help with automating the process of generating these reports. A month only takes a few minutes. Longer periods take much longer.
- Table of working set, read, and re-read for monthly, quarterly, and year.
