Hi, guys

I am a beginer of SU2, I have the same problems with building SU2 on Linux/MacOS, and what i do for building the codes is

rm -rf build
export CC=mpicc.mpich
export CXX=mpicxx.mpich
export CXXFLAGS="-march=native -funroll-loops -ffast-math -fno-finite-math-only"
./meson.py build --optimization=2 --warnlevel=3 --prefix=$PWD/build -Dcustom-mpi=true -Dwith-omp=true -Denable-mpp=true
sudo ./ninja -C build install -j 4
(I get hints from this post MPI issues on debian Debian 11 bullseye , unfortunately i cannot reply this post so i created a new thread)

it is weird the when i run with SU2_CFD it output:

[yufanpro-virtual-machine:214352] *** An error occurred in MPI_Win_create
[yufanpro-virtual-machine:214352] *** reported by process [3228696577,0]
[yufanpro-virtual-machine:214352] *** on communicator MPI_COMM_WORLD
[yufanpro-virtual-machine:214352] *** MPI_ERR_WIN: invalid window
[yufanpro-virtual-machine:214352] *** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,
[yufanpro-virtual-machine:214352] *** and potentially your MPI job)

but it can be run with mpirun -n 1 --mca osc ucx SU2_CFD, I donot know if this is equal to run with SU2_CFD.

I suffered from this a lot >_<, i am really looking forward to your hints or help.



Best Regards，

did you forget -Dwith-mpi=enabled?

-Dwith-mpi=enabled -Dcustom-mpi=false

Also check in the meson output that the compiler it uses is mpich and not just gcc .

Hi Sir,

Thank you for your advice, i suddenly understand this is caused by the interference of openmpi and mpich in my VMware. I uninstall those two package, and install mpich to fix the problem.

Thank you very much ^_^!

Yours,
