- Then need a conversation on when to merge repos.

Has improved. 233 failures, currently on Cisco.
- Cisco - Many Cisco failures are local cluster issues. Art is working on cleaning up.
Jeff put in a patch into MTT to allow thread hangs to be marked as hangs.
nVidia failures are all PMIx failures.
