Hi all

I am trying to run SU2 parallel in a Cluster which has 2 nodes, one node is ubuntu 18.04 and the other node is centos 7. All the steps are followed to create the cluster and NFS mounting is done between 2 nodes in the directory "cloud".

I have installed SU2-mpi and mpich-4.0.2 and everything is setup properly in the cloud directory which is NFS mounted on both systems.

so when I run an SU2 sample using the command
time mpiexec -n 6 --host BLTSP00316,bltsw06032 ../../../SU2_CFD inv_ONERAM6.cfg

The iterations are starting and the process is divided into into nodes and takes place in parallel.

But when it comes to the end of the result where it prints the i/o outputs like creating the restart_flow.dat files it throws error there,

so it says error in bool and it is unable to open the restart file. I am confused why this is happening? is it because i am trying to write from two different nodes into a same file at a time or any other permission issues?

Please help me with this error! Thanks in advance

does it work when you run mpirun on only the ubuntu node on multiple cores?

I encountered the following error while working on the "Constrained shape design of a transient turbine air at a cte. CL" case. I tried opening restart_ Flow.dat file, but cannot be opened.

Hi ,

I experienced something similar time ago and in the .cfg file, this option should be marked as YES

SOLUTION_FILENAME= solution_flow.dat

READ_BINARY_RESTART= YES

It might help to your case.

Best regards,
