[petsc-users] Question on DMDA in example ex11f90

[Wienand Drenth]

Hello,

Following suggestions on a previous query on handling distributed arrays, I
set forth to use the DMDA path.

I installed the latest petsc version (3.2 patch 3), and went looking into
example 11f90 (in src/dm/examples/tutorials) for inspiration.

Compilation of the example went ok, but when I run the example I get an
error:

12:25] examples/tutorials 81 > mpiexec -n 1 ex11f90

Petsc was installed with the following config options:

--PETSC_ARCH=${PETSC_ARCH} --with-mpi-dir=${MPI_DIR}
--download-f-blas-lapack=1 --with-shared-libraries=1 --with-debugging=no
--download-mumps=1 --with-mumps=1 --with-fortran-interfaces
--download-scalapack=1 --with-scalapack=1 --download-blacs=1 --with-blacs=1
--download-parmetis=1 --download-hypre=1

PETSC_ARCH is linux-gnu, and I have a locally installed MPI version, with
MPI_DIR being the location. I use the openmpi 1.4.3 version of MPI.

Thank for any support and help,

kind regards,
Wienand
