Thanks for the report. I'll look into it, but I'll be traveling for
another week and a half--so it might be a little while.

Examples not working in MPI
by Peter17
Dear Andreas,
I would like to adapt the Laplacian and Diffusion operators for my own
usage, but I can't make the corresponding examples work in MPI...
For examples heat/heat.py, poisson/poisson.py and
poisson/helmholtz.py, If I replace:
rcon = guess_run_context()
by
rcon = guess_run_context(['mpi'])
And run:
mpirun -n 2 python heat.py
Then, I get the following error:
Traceback (most recent call last):

RuntimeError: flux '<Flux((-1)*(Normal(0)*Int[0] +

However, these examples are working very well in CPU and (except
helmholtz.py) single GPU...
Other examples such as advection/advection.py and wave/wave.py are
working well in CPU and MPI...
Can you please have a look at them?
Thanks a lot in advance
Best regards
