Heya! Currently systemd doesn't have this kind of distributed scheduler . Though I think it would be very interesting to explore (systemd-distributed seems to be a fun name).
At some point coreos had a distributed version of systemd that did sort of exactly what you want https://github.com/coreos/fleet <ttps://github.com/coreos/fleet> . However it is now unmaintained as they moved their focus to Kubernetes for orchestrating workloads.
