Intro+news
----------

GlideInWMS
----------
- MK: Contacted Brookhaven: they wanted flocking so can submit to local
      cluster and then overflow to FermiGrid. MK suggested they have
      a submit node there which goes to DUNE global pool.
- Discussion about whether to allow/enable submission via DUNE workload
  system to private capacity, just for users at that site

  CMS can do this:

  Dangers of fragmentation vs unlocking extra resources for analysis

- AM: We should agree a position on this in case sites ask for it. Compare
      previous private storage vs pledged storage discussions (pledged storage
      must be centrally managed and registered using RUCIO; files on private
      storage may also use central tools for management.)

User tools (inc jobsub)
-----------------------
- KH: Moving to jobsub lite (ditching server side, talks to Condor schedd 
      directly.) Easier to deploy. Currently assumes Kerberos and users that
      to make proxy (unless you override it.)
- MK: Will that use tokens?
- KH: I expect so in the future.
      Should be able to work from laptops with cvmfs already. If a user
      creates a proxy and tells jobsub to use it, then don't need to use
      a FNAL Kerberos ticket
- AM: Will we stick with jobsub or move analysis users to POMS?
- MK: Some analysts have tried POMS. Monitoring is much better.
- AM: Is there are command line interface? Expect some analysis users will
      ask for that for POMS.
- KH: Yes. Not used that much. Can submit multijob runs from command line.
