Research direction

No files, tests, or entry points are named. First review the existing serial-function execution path and the mpi4py.futures.MPIPoolExecutor option, then clarify whether this feature is still wanted given the stated flux-core installation path; done should include an agreed scope and validation for scaling beyond one node.

Description

enhancement

At the moment the flux framework or SLURM workload manager are required to scale beyond a single node. We could in principle offer this for serial functions just based on mpi4py using the mpi4py.futures.MPIPoolExecutor. Still given the simple installation of flux-core via conda I do not think this is required any more.
