Thanks, sounds good. @ketancmaheshwari Please make sure psi-j-ci-run runs daily and reports to https://testing.exaworks.org/summary.html

Andes has test set up via an ORNL GitLab mirror and using that GitLab's CI hooks. That is not working too well - the tests are frequently failing for hanging NSF file handles and other PSIJ unrelated stuff.
The cron-based test runs seem to be fairly stable on other machines, so I'll be going to try that on Andes also.
