The mpi4py was installed by me with  "pip install mpi4py"

If I uninstall it, then run "which mpi4py" or "pydoc mpi4py", nothing is found.
I don't understand "Stampede for instance has mvapich2 available which has mpi4py". 

What do you mean and how can I enable it ?

Then, I run

Nothing found.
Thus, I supposed ompi_mpi_char is not in /opt/apps/intel15/mvapich2/2.1/lib/libmpi.so.12

Any ideas ?

Hi Tao,

May I ask which machine you are using?

Stampede for instance has mvapich2 available which has mpi4py, and works with PETSc/firedrake.

Since firedrake depends on mpi4py, which depends on open-mpi or mpich. But the server I used does not have them, only having intel mpi.  The following is a test.

python -c "from mpi4py import MPI"

Then, I run
nm /opt/apps/intel15/impi/5.0.2.044/intel64/lib/libmpi.so.12 | grep ompi_mpi_char

Nothing is returned, it seems there is no such symbol in Intel MPI implementation.

Does this suggest that firedrake cannot work with intel mpi implementation ?

Please see this issue for more details.
Could you answer my questions one by one ?

Thanks a lot for your help.

Make sure you have all the other dependencies installed and then use the install script with the —no-package-manager option.
