If you are using MacPorts (it looks like you are), you should have seen this note on installation (or similar, depending on what you installed): +--- MPICH Usage note ---- | The mpicc wrapper (and friends) are installed as: | | /opt/local/bin/mpicc-mpich-mp (likewise mpicxx, ...) | | To make mpich-default's wrappers the default (what you get when | you execute 'mpicc' etc.) please run: | | sudo port select --set mpi mpich-mp-fortran +------------------------- This is because MacPorts support installing multiple mpich instances (compiled with & wrapping different compilers) side-by-side, so you have to either explicitly call the correctly named tools, or use the 'sudo port select ...' line -- the last line of the note above -- to install symlinks for the default names (mpicc, mpiexec, etc.) in /opt/local/bin. - Eric On Wed, Jul 16, 2014 at 7:17 AM, Thakur, Rajeev <[email protected]> wrote:

Make sure you run the mpirun script also from the MPICH directory. Use the script called mpiexec from there.

Dear Rajeev,

Thanks for your reply. I now realize mpich is under /opt/local/include/mpich-mp. There is another under /usr/local/include that has an mpif.h with include "mpif-common.h". These are by Indiana University/Stuttgart/UC/Cisco.

mpif90 -I/opt/local/include/mpich-mp -o tst tst.f (containing include "mpif.h" in tst.f) mpirun -np 2 ./tst

gives a runtime error

1275069467 1275069468 1275070495 (=MPI_INTEGER,MPI_REAL,MPI_DOUBLE_PRECISION) 1275069467 1275069468 1275070495 *** An error occurred in MPI_Comm_rank *** reported by process [140735101665281,140733193388032] *** on communicator MPI_COMM_WORLD *** MPI_ERR_COMM: invalid communicator *** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort, *** and potentially your MPI job) (same for 2nd process)

Clearly, there I have an initialization error on the basic mpi variables. Is there a possible mix-up between these two mpi packages?

Best,

Henry

What is mpif-common.h? You need to include mpif.h and provide the path to the mpich include directory. The problem you are seeing is caused because the wrong mpif.h is being picked up.

Hi,

Perhaps someone can provide a solution to what seems to be a problem with installation of mpich.

I installed ifort (intel) and mpich (via port install), compile a basic test program mpif90 -I/usr/local/include -o tst tst.f (here "I/usr/local/include" is included to find mpif-common.h),

PROGRAM mpitest integer ierr,my_rank,nm_prcs include "mpif-common.h" call MPI_INIT(ierr) write(*,*)MPI_INTEGER,MPI_REAL,MPI_DOUBLE_PRECISION call MPI_COMM_RANK(MPI_COMM_WORLD,my_rank,ierr) call MPI_COMM_SIZE(MPI_COMM_WORLD,nm_prcs,ierr) write(*,*)'MPI:',my_rank,nm_prcs,ierr call MPI_FINALIZE(ierr) end

and do mpirun -np 2 ./tst. The result is

7 13 17 MPI: 0 1 0 7 13 17 MPI: 0 1 0

It shows that nm_prcs = 1 and both processes show the same my_rank = 0, even though ierr =0.

The initialization in mpirun seem to fail, to assign a proper process count 2.

Any ideas on what's amiss?

Many thanks,

Henry. _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
