Hello,
I'm trying to solve an equation in parallel my code works fine on his own.
And
mpirun -np {# of processors} python -c "import fipy; fipy.test('--trilinos')"
command also works except 2 tests. But when I try to run my code with
"mpirun -np 8 python __main__.py --trilinos" command I get import
error. I paste end of the error message.
I can share my code and all error if needed. But I first want to know
is it a known issue with a simple fix or not ?
Kindest Regards,
Serbulent

It seems that [at least] one of the processes that was started with
mpirun did not invoke MPI_INIT before quitting (it is possible that
more than one process did not invoke MPI_INIT -- mpirun was only
notified of the first one, which was on node n0).
File "/usr/lib/python2.7/site-packages/fipy/tools/__init__.py", line 73,
in _getComms
mpirun can *only* be used with MPI programs (i.e., programs that
invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec" program
to run non-MPI programs over the lambooted nodes.
