I am running small input to check the SU2 v8.0.0 Harrier on cluster of two computers each has 8 CPU's. Each CPU prints the output to the log file. I get each line 16 times in the log file.

How to fix it so as in Version 7.5.1 only one cpu will print the output?

This happens when you do not compile with mpi support, you should check the meson command and also the output to see if mpi support is added.

Hello, what does it mean to setup PKG_CONFIG_PATH variable ?

Do you use openmpi or mpich?


Do you get these kind of problems:
SU2 parallel install build from source failed


Also check here:
https://su2code.github.io/docs_v7/Bu...n-is-not-found


if you have mpich, you need to use these meson options:
Code:
-Dcustom-mpi=true -Dextra-deps=mpich

Thank you,

Although I try to launch SU2 with /applhome/mpich/mpich-4.1.2-rocky87/bin/mpirun

the program tries to open the /usr/lib64/openmpi/lib/libmpi.so.40

if you have multiple mpi's installed, then you can set the active mpi using
Code:
update-alternatives --config mpi
update-alternatives --config mpirun
You can check the correct linking by following the symbolic links of mpirun for instance:

Code:
 which mpirun
/usr/bin/mpirun
 ls -lrt /usr/bin/mpirun
/usr/bin/mpirun -> /etc/alternatives/mpirun
ls -lrt /etc/alternatives/mpirun
/etc/alternatives/mpirun -> /usr/bin/mpirun.mpich
or you can uninstall one of the mpi's.
