Description
Parsl providers assume a pilot job model, where a single manager runs per node. This model conflicts with the model that
MPIExecutoruses where the scheduler starts a single manager on the entire job which then launches MPI apps. This PR adds a warning to documentation cautioning use ofcores_per_nodein the SlurmProvider and similar options.This PR comes Christopher Harrop from NOAA reported on the help channel.
