Nimbus, and by extension the scheduler, see these heartbeats and views the supervisor as multiple supervisors - one per configured NUMA zone. Nimbus schedules topologies and assignments accordingly. The supervisor reads all assignments with the prefixed assignments and then pins each worker to the NUMA zone according to the numa id in the assignment.
