  • Public_input_files: How is this different than transfer_input files and when would one want to use it instead of files or URLs with transfer_input_files?
  • How can we  data path for transfer_input_files to our clients given multiple networks.  Currently we assume it will use the 1Gb link but we have IB links.    Is there a way for condor to use the IB link just for transferring files, is that hostname based ? Other ideas?

  • Are there known issues with distributed scratch via NFS or Lustre w.r.t tmpdir or other,  e.g. OpenMPI complains about tmpdir being on network FS?
    • Any general best practices to support MPI in terms of class ads or other.

  • What does DAGMan do when a process returns an error code (like 1)?  Is there a way DAGMan can be told to ignore errors?
