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

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): File "heat.py", line 165, in <module> main() File "heat.py", line 131, in main rhs = op.bind(discr) File

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 -- Peter Potrowl
