Invalid communicator #60

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Although the code is NOT executed in parallel, I got the following error 
message while
 executing the code doc/manual/tutorial/stokes_Dirichlet_Dirichlet.cpp which manipulates P2P1G3 objects:

-------------------------
Fatal error in PMPI_Errhandler_set: Invalid communicator, error stack:
PMPI_Errhandler_set(118): MPI_Errhandler_set(comm=0x247ef740, errh=0x247f0460) 
failed
PMPI_Errhandler_set(70).: Invalid communicator
-------------------------

No errors are noticed for P2P1G1 or P2P1G2.

This was due Feel++ being compiled with mpich2 and other libs being compiled 
with openmpi

be careful that in Debian it seems that the default now is mpich2 
use update-alternatives --config mpi
to set the proper mpi implementation

to fix this issue I selected openmpi
