Delay is not the point, you start all independent tasks and then dependent tasks for each are arranged to wait for all their precedents. Now, only one process can wait for each running process, so if many processed need to know what is done, a log file, directory of marker files or other database can track progress, and you can check progress in a loop every N seconds. You could write a supervisor that knows the prereqs of every new process. You could put the prereqs in a SQL db, same db as the completions, so you can query what is not run and no prereq is missing, and launch any found. You would be writing ControlM or Tivoli TWS and such.
