[petsc-dev] [Fortran] MatLoad() error: MatLoad is not supported for type: mpiaij!

[Leo van Kampenhout]

Hi all,

I'm having trouble with MatLoad on Petsc-Dev. Not sure if this problem also
exists in the main PETSc 3.1 since my code won't compile on that.
The problematic calls are as follows:

      call PetscViewerBinaryOpen(PETSC_COMM_WORLD,file2,
     &     FILE_MODE_READ,fd,ierr)
      call DAGetMatrix(da,MATMPIAIJ,A,ierr)
      call MatLoad(A,fd,ierr)

which supposedly will load a matrix A which is stored by the following
commands:

      call PetscViewerBinaryOpen(PETSC_COMM_WORLD,file2,
     &     FILE_MODE_WRITE,fd,ierr)
      call MatView(A,fd,ierr)

by another program (on a single core). The MatLoad() does work perfectly on
a single core, however two or more cores make the program crash with the
following error (see below)
The programcall is
 mpirun -n 2 ./main

Is something broken with Petsc or do I need to set some extra parameters?
Thanks in advance,

Leo van Kampenhout

PS. I'm using a build from last friday, since when I updated petsc-dev today
using Mercurial I couldnt get it to configure or compile :S (which is
another subject)
