Fwd: [mpi-forum/mpi-issues] MPI RMA integer interfaces for AINT arguments (Issue #528)
by Joachim Protze 29 Nov '21

29 Nov '21

Hi tools folks, We should have an eye on this issue. Has this the potential to break PMPI Wrappers? Best Joachim -------- Weitergeleitete Nachricht -------- Problem RMA absolutely did the right thing with |MPI_Aint| size and displacement arguments. In C, it is no problem to pass 32b integers to these arguments when AINT is 64b, because C type promotion rules just work. In Fortran, I cannot do this, because an integer literal is not compatible with an AINT argument. I find it tedious to have to declare a variable just for this, or to explicitly cast with |integer(100,MPI_ADDRESS_KIND)|. Fortran ! USE mpi_f08 ! MPI_Win_allocate(size, disp_unit, info, comm, baseptr, win, ierror) ! USE,INTRINSIC :: ISO_C_BINDING, ONLY : C_PTR !INTEGER(KIND=MPI_ADDRESS_KIND),INTENT(IN):: size !INTEGER,INTENT(IN):: disp_unit ! TYPE(MPI_Info),INTENT(IN):: info ! TYPE(MPI_Comm),INTENT(IN):: comm ! TYPE(C_PTR),INTENT(OUT):: baseptr ! TYPE(MPI_Win),INTENT(OUT):: win !INTEGER, OPTIONAL,INTENT(OUT):: ierror program main use iso_fortran_env use mpi_f08 implicit none integer(kind=MPI_ADDRESS_KIND):: as= 100 type(c_ptr):: XA type(MPI_Win):: WA TYPE(MPI_Comm):: comm= MPI_COMM_WORLD call MPI_Win_allocate(as,1, MPI_INFO_NULL, comm, XA, WA) call MPI_Win_allocate(100,1, MPI_INFO_NULL, comm, XA, WA) end program main % mpifort y.F90 y.F90:20:60: 20| call MPI_Win_allocate(100, 1, MPI_INFO_NULL, comm, XA, WA) | 1 Error: There is no specific subroutinefor the generic'mpi_win_allocate' at (1) C #include <mpi.h> int main(void) { MPI_Aint as =100; int * XA; MPI_Win WA; MPI_Win_allocate(as,1, MPI_INFO_NULL, MPI_COMM_WORLD, XA, &WA); MPI_Win_allocate(100,1, MPI_INFO_NULL, MPI_COMM_WORLD, XA, &WA); } % mpicc y.c&& echo SUCCESS SUCCESS Proposal Use Fortran does polymorphism and add subroutine declarations for default integer arguments. This proposal applies not to just MPI_Win_allocate but any RMA function that uses AINT scalar arguments.

Hi Joachim, all, ok. Then let's cancel today. I would also cancel next week due to people probably having conflicts with the SC program. So the next meeting would be in two weeks, again on handle introspection.
