Problem of MPI?

[Tsubasa]

Hello,

Now I am using CS(version6.0.5) on Linux(version20).

When I try to run a simulation with the paralellization, some errors occurred.
I am not familiar with this.

Would someone give me tips or solutions?
When I run a simulation with 1 process, it worked, but after 2 or more process it did not work.

Best regards,
Tsubasa

Hello,

This looks like an installation issue. Could you provide the info recommended in the installation forum section ? viewtopic.php?f=3&t=12

Hello!

I met the same problem with you these days.The case only can be run with one process and when I set the process number more than one the same error ouccers like:

Parallel code_saturne on 10 processes.

Then I search on this website and found this post.Have you solved this problem?It has been a long time since this problem was posted,but I would be very grateful if you could give me some help or advice!Thank you so much!

Hello,

Actually, I did not solve this problem at that time, and I did not remember correctly how I solved this.
I guess I re-installed a few times. Then after that, I did not face this problem.

Sorry I cannot give you good answer, but anyway you should provide the info recommended in the installation forum section ? viewtopic.php?f=3&t=12
