[mpich-discuss] configuration problem

Tue Apr 27 14:02:38 CDT 2010

Thanks for your reply. I will look into it. Note that I am relatively new to this, I do have another question related to your answer. The code I am trying to compile is successfully run in parallel on another cluster (this cluster uses Redhat, various mpich1 versions, e.g. mpich-1.2.5..12, and various versions ofIntel FORTRAN compiler (ifort), e.g. 7, 9 and 12). How is it that I can have a bug in the MPI program as I directly copied the whole code on to my workstation? Is this because there are discrepancies between mpich1 and mpich2? If so, MPI_Scatter routines seems to be correctly working on one cluster with mpich1 and not on my workstation with mpich2? This is why I tried to imitate the other cluster as much as possible and tried installing mpich1, which gives yet another problem, i.e.  the configuration problem, described below.

Have you got an anwer for this maybe? And did you have a look at my mpif.inc file as other people using the other cluster tell me it is compatible and in use with different mpi versions.

Thanks

 Kate

Kate,
     You have to use the mpif.h file that comes with the MPI
implementation, not from some other MPI implementation. With MPICH2, you
have to use MPICH2's include file.

The error with MPI_Scatter indicates there is a bug in your MPI program.
You are using the same buffer as sendbuf and recvbuf, which is not
allowed in MPI. You can use the MPI_IN_PLACE argument instead, as
described in the MPI standard.

I would recommend using MPICH2 instead of trying to get MPICH-1 to work.
