5 Hands-on: Submitting to HTCondor-CE with tokens

Speaker: Brian Hua Lin (University of Wisconsin - Madison)

Requesting WLCG tokens with oidc-agent: https://opensciencegrid.org/technology/software/requesting-tokens/

Example submit file using condor_submit -remote:

    executable = /bin/env

    output = env.out

    error = env.err

    log = env.log

    # can be skipped if there is a token in the default location:
    # /tmp/bt_u$(id -u)

    +SciTokensFile = "<path to token>"

    queue

For improved management of submitted jobs, submit "Grid Universe" jobs from an HTCondor access point: https://htcondor.github.io/htcondor-ce/v5/remote-job-submission/#submit-the-job

6 Open Discussion / Hackathon

Ideas for discussion topics:

1) Vault and its integration with HTCondor.
2) How to authenticate the submission of user jobs.
3) Set up demo HTCondor-CEs both with OSG and at CERN to demonstrate interoperability (including both SciTokens and WLCG tokens).
