Revisit Pegasus after GPGrid refactor
We evaluated Pegasus earlier in 2017 to see how well it would interact with the existing FIFE tools, namely Jobsub. We decided that since Pegasus was tightly coupled to HTCondor commands (i.e. it was not easy to make it do "jobsub_submit" as opposed to "condor_submit") and it was somewhat more difficult to make work with glideins, that we should not expend effort now to modify jobsub to interface with it. After the GPGrid refactor is complete in the fall, and glideins will not run FIFE jobs, it may be easier to make everything interface. We can look at things again after the refactor is complete and we know how FIFE users will be submitting jobs in the long term.
