[petsc-users] pctype hmpi

[George Pau]

Hi,

I have some issues using the -pctype hmpi.  I used the same setting found
at

http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/PC/PCHMPI.html

i.e.
-pc_type hmpi
-ksp_type preonly
-hmpi_ksp_type cg
-hmpi_pc_type hypre
-hmpi_pc_hypre_type boomeramg

My command  is

mpiexec -n 1 myprogram

But, I get

[gilbert:4041] *** An error occurred in MPI_Bcast
[gilbert:4041] *** on communicator MPI_COMM_WORLD
[gilbert:4041] *** MPI_ERR_COMM: invalid communicator
[gilbert:4041] *** MPI_ERRORS_ARE_FATAL (your MPI job will now abort)

with openmpi.  I get similar error with mpich2

Fatal error in PMPI_Bcast: Invalid communicator, error stack:
PMPI_Bcast(1478): MPI_Bcast(buf=0x7fffb683479c, count=1, MPI_INT, root=0,
comm=0x0) failed
PMPI_Bcast(1418): Invalid communicator

I couldn't figure out what is wrong.    My petsc is  version 3.3.3 and the
configuration is -with-debugging=0 --with-mpi-dir=/usr/lib/openmpi
--download-hypre=1 and I am on a Ubuntu machine.

Note that with the default pc_type and ksp_type, everything is fine.  It
was also tested with multiple processors.  I wondering whether there are
some options that I am not specifying correctly?
