Subject: Re: [OMPI users] MPI_TYPE_CREATE_SUBARRAY not in mpif90 library
What version of Open MPI are you using?
I just checked a trivial f90 MPI program and MPI_TYPE_CREATE_SUBARRAY seemed to
work ok.
I am not a fortran expert, but when I have seen this type of error message
before, it *usually* meant that there was a type mismatch between the types
passed to the function and the function signature available in the f90 module.
I.e., the compiler found a function matching the *name*, but wasn't able to
find a match for the *type signature*.
Here's Open MPI's declaration of MPI_TYPE_CREATE_SUBARRAY:
-----
interface MPI_Type_create_subarray
subroutine MPI_Type_create_subarray(ndims, size_array, subsize_array,
start_array, order, &
oldtype, newtype, ierr)
integer, intent(in) :: ndims
integer, dimension(*), intent(in) :: size_array
integer, dimension(*), intent(in) :: subsize_array
integer, dimension(*), intent(in) :: start_array
integer, intent(in) :: order
integer, intent(in) :: oldtype
integer, intent(out) :: newtype
integer, intent(out) :: ierr
end subroutine MPI_Type_create_subarray
end interface
-----
One thing you might want to double check is that OMPI was compiled with
MPI_REAL8 support (since MPI_REAL8 was passed to the subroutine). Run this:
-----
shell$ ompi_info --all | grep real8
Fort have real8: yes
Fort real8 size: 8
Fort real8 align: 8
shell$
-----
Finally, note that Open MPI doesn't have many of the F90 symbols that you might
expect in libmpi_f90.so because most of our F90 support is "direct pass
through" to the F77 subroutines. Specifically, our F90 mpi module simply
provides compile-time checking for expected signatures, but the subroutine call
is actually automatically linked against the corresponding symbol in
libmpi_f77.so. Only a few subroutines -- i.e., the ones that have multiple
different type signatures -- actually appear in libmpi_f90.so.
Meaning: MPI_TYPE_CREATE_SUBARRAY only has one type signature. So it's normal
/ expected that you don't see /mpi_type_subarray/i in libmpi_f90.so.
