Hey there! It depends on exactly how transparent you're talking, but I rewrote some Fortran and Honeywell assembly to 'C' on lowest-cost-bidder unix workstations on behalf of NASA in 91 or 92? We used NQS [1] to distribute the workload across the nodes and it worked pretty well. Well enough for NASA to retire the mainframe. The idea is hardly unique or novel - I believe DEC's clustering software allowed something similar? [2]
Popular cross platform proprietary tooling for this is Control-M, but I didn't work personally with it. There are now also batch systems with executors on k8s or Mesos, and in a simplified sense apache airflow is often used for this
