For running the exact same command(s) on a bunch of machines, you
might want to look into a tool like func or Cluster SSH. Parallel is
more for "I have a bunch of jobs and I don't really care where they
run."
That said, it's certainly possible, with something like:
$ parallel -q -j0 ssh {} 'echo {}; parallel md5sum < files.txt' < hosts.txt
This assumes files.txt (and parallel) is on all the hosts.
