# Purpose: Federated job cancellations

# Reqs:    1. Using slurmdbd accounting storage type and is up
#          2. fed_slurm_base is defined in globals.local - set to directory that
#          has access to each federation configure (fedc1, fedc2, fedc3).
#          Eg.
#          fedr/slurm/ (src)
#          fedr/fed1/bin
#          fedr/fed1/sbin
#          fedr/fed1/etc
#          fedr/fed1/...
#          fedr/fed2/...
#          fedr/fed3/...
#          3. controllers are up and running.
