At the same time the documentation says:
--jobs N
-j N
--max-procs N
-P N Number of jobslots on each machine. Run up to N jobs in
parallel.
0 means as many as possible. Default is 100% which will run
one
job per CPU core on each machine.
So it should by default run a single job on each machine.

[...] GNU parallel will log into --jobs number of
computers in parallel and run the job on the computer. -j
adjusts how many
computers to log into in parallel.
So add -j0.
