`MPI_COMM_TYPE_HW_GUIDED` and is more generic. There would be no need
for both, provided that `MPI_COMM_TYPE_RESOURCE_GUIDE…

Reading [Halo_mod](https://github.com/Goddard-Fortran-Ecosystem/pFUnit/blob/master/Examples/MPI_Halo/src/Halo.F90) I noticed, that "include…

Currently, users have to select DLB libraries either with C MPI bindings or Fortran MPI bindings. E.g. `libdlb_mpi.so` vs. `libdlb_mpif.so`. This works well in scenarios where the user of DLB is famil…
