i am aware of dagman, but as far as i can tell it does not satisfy the
use case as the complete graph must be defined prior to A's submit
am i crazy or missing the obvious? any advice is greatly appreciated.
While the structure of the DAG must be defined in advance (e.g., A runs
before B), the details of the individual jobs do not have to be settled
until the moment they're submitted by DAGMan [*]. So yes, you can
submit a DAG where the submit file for job B is almost empty, and job A
(or its POST script) can in fact define job B's details.
[*] the one exception is each job's "log" file specification -- that is
the one submit file line that must be exist for each job at the time
the DAG is started.
