FWIW, the nbc module was not initially specific to Open MPI, and hence used
standard MPI subroutines.
In this case, we can avoid the issue by calling internal Open MPI
subroutines.
This is an

we pass in an MPI_Type_contiguous with an MPI_Datatype of MPI_C_FLOAT_COMPLEX
which ends up being the size of multiple rows of the image (based on the number
