Thank You, Nick and Gilles,
I hope the administrators of the cluster will be so kind and will
update OpenMPI for me (and others) soon.
Greetings
Michael

1.10.0 with Intel-Ftn-compiler
Thanks Nick for the pointer !
Michael,
good news is you do not have to upgrade ifort,
but you have to update to 1.10.1
(intel 16 changed the way gcc pragmas are handled, and ompi has been
made aware in 1.10.1)
1.10.1 fixes many bugs from 1.10.0, so I strongly encourage anyone to
use 1.10.1
Cheers,
Gilles

Maybe I can chip in,
We use OpenMPI 1.10.1 with Intel /2016.1.0.423501 without problems.
I could not get 1.10.0 to work, one reason is:

On a side-note, please note that if you require scalapack you may need

Sorry, Gilles,
I cannot update to more recent versions, because what I used is the
newest combination of OpenMPI and Intel-Ftn available on that cluster.
When looking at the list of improvements on the OpenMPI website for
OpenMPI 1.10.1 compared to 1.10.0, I do not remember having seen this
item to be corrected.

Michael,
I remember i saw similar reports.
Could you give a try to the latest v1.10.1 ?
And if that still does not work, can you upgrade icc suite and give it
an other try ?
I cannot remember whether this is an ifort bug or the way ompi uses
fortran...
Btw, any reason why you do not
Use mpi_f08 ?
HTH

Dear developers of OpenMPI,
I am trying to run our parallelized Ftn-95 code on a Linux cluster
with OpenMPI-1-10.0 and Intel-16.0.0 Fortran compiler.
In the code I use the module MPI (“use MPI”-stmts).
However I am not able to compile the code, because of compiler error
messages like this:
/src_SPRAY/mpi_wrapper.f90(2065): error #6285: There is no matching
specific subroutin for this generic subroutine call. [MPI_REDUCE]
The problem seems for me to be this one:
The interfaces in the module MPI for the MPI-routines do not accept a
send or receive buffer array, which is
actually a variable, an array element or a constant (like MPI_IN_PLACE).
Example 1:
This does not work (gives the compiler error message: error
#6285: There is no matching specific subroutin for this generic
subroutine call )
ivar=123 ! ßivar is an integer variable, not an array
*call* MPI_BCAST( ivar, 1, MPI_INTEGER, 0, MPI_COMM_WORLD), ierr_mpi
) ! ß- this should work, but is not accepted by the compiler
only this cumbersome workaround works:
ivar=123
allocate( iarr(1) )
iarr(1) = ivar
* call*MPI_BCAST( iarr, 1, MPI_INTEGER, 0, MPI_COMM_WORLD,
ierr_mpi ) ! ß- this workaround works
ivar = iarr(1)
deallocate( iarr(1) )
Example 2:
Any call of an MPI-routine with MPI_IN_PLACE does not work, like
that coding:
*if*(lmaster) *then*
*call* MPI_REDUCE( MPI_IN_PLACE, rbuffarr, nelem, MPI_REAL8, MPI_MAX &
! ß- this should work, but is not accepted by the compiler
,0_INT4, MPI_COMM_WORLD, ierr_mpi )
*else* ! slaves
*call* MPI_REDUCE( rbuffarr, rdummyarr, nelem, MPI_REAL8, MPI_MAX &
,0_INT4, MPI_COMM_WORLD, ierr_mpi )
*endif*
This results in this compiler error message:
/src_SPRAY/mpi_wrapper.f90(2122): error #6285: There is no matching
specific subroutine for this generic subroutine call. [MPI_REDUCE]
call MPI_REDUCE( MPI_IN_PLACE, rbuffarr, nelem, MPI_REAL8,
MPI_MAX &
-------------^
In our code I observed the bug with MPI_BCAST, MPI_REDUCE, MPI_ALLREDUCE,
but probably there may be other MPI-routines with the same kind of bug.
This bug occurred for : OpenMPI-1.10.0
with Intel-16.0.0
In contrast, this bug did NOT occur for: OpenMPI-1.8.8 with
Intel-16.0.0
OpenMPI-1.8.8 with Intel-15.0.3
OpenMPI-1.10.0 with
gfortran-5.2.0
Greetings
