Hello guys!
I've managed to successfully run in 1 node consuming up to 2 processes. Quote:

Hi,
Can you please share the compiler/MPI type and versions that you are using? Also, can you try to call SU2_DDC as a stand alone module with something like: mpirun -np 8 SU2_DDC inv_ONERAM6.cfg to verify whether there is a problem on the Python side or on the C++ side? T |

Im using Metis 5.0.2 along with OMPI 1.4. I get the same error calling mpirun directly. So it's a C++ problem. Quote:

Hmm.. can you share the options that you sent to the configure process? And does this happen for every test case that you run in parallel?
