Error opening file: "residuals.csv"

Dear CS experts
I am new to CS and trying to run a small case on Code Saturne which is recently installed on our cluster.
While I run the case on one node (28 CPUs) it worked good but If I run the same setup on multiple nodes it stops with following error :

"System error: Remote I/O error

/work/projects/Code_Saturne/src/code_saturne-5.0.9/src/base/cs_time_plot.c:362: Fatal error.

End of stack

application called MPI_Abort(MPI_COMM_WORLD, 1) - process 46"

Can you please help me to resolve it.
I attached the RESULT folder for both cases
RUN1.zip= failed on 2 nodes
RUN2.zip= OK on 1 node

Regards

Hello,

Could you check with the attached file (adding it in the SRC folder of your case is OK for a first test, and it it works, replacing the one in the code sources and reinstalling is the clean solution) ? It seems the file was opened for all processors (whre it s not necessary), so tricky things can happen based on your file system.

Best regards,

Yvan

Hello,

Ok great. The fix has been commited to development and active maintenance branches, so will be included in 5.0.10, 6.0, and 5.3.3.

Best regards,

Yvan
