newbie MPI error out of box on ubuntu

cfd77 · August 16, 2024, 13:03

Hi SU2 friends,

I am new to SU2.
I git cloned SU2 from git repository: https://github.com/su2code/SU2
I have also tried SU2 8.0.1

I did
./meson.py build
sudo ./ninja -C build install

When I run
SU2_CFD inv_NACA0012.cfg
in QuickStart folder, I got this error:

*** An error occurred in MPI_Win_create
*** reported by process [3211657217,0]
*** on communicator MPI_COMM_WORLD
*** MPI_ERR_WIN: invalid window
*** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,
*** and potentially your MPI job)

Since I did not build with -Dcustom-mpi=true -Dextra-deps=mpich
I assume when I run SU2_CFD mpi will not be involved.
Why am I getting MPI related errors?

How can I run the QuickStart without getting these errors?

Thanks very much!

Maybe you still compile with mpi.
You can explicitly disable mpi using

Code:

Dwith-mpi=false

That seems to be a common thing on ubuntu ... i dunno what to really do about it either.

you can use the following which should do the trick (it does for me on all ubuntu systems)

Code:

mpirun -n 1 --mca osc ucx SU2_CFD ...

I have that trick/hack from https://github.com/open-mpi/ompi/issues/10726

hope that kinda helps, Tobi

If you are using Ubuntu 24 which is the latest release, you can try to return Ubuntu 22 or 20. I guess if you don't specify anything SU2 compiles with Dwith-mpi=auto and if there're openmpi and mpich both installed in your computer it creates some problems.
