Hello, i compiled in parallel mode Telemac 8.0.2 without Mascaret. All went ok, but when i try to run a exemple case, every time the same error:
"Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:
#0 ffffffffffffffff
#1 ffffffffffffffff
#2 ffffffffffffffff
...
#22 ffffffffffffffff"
I tryed with the MPI login, but is correct. I searched in the forum but i not found a solution...Can everyone help me?
Attached the screenshot of error and the cfg file.
Thaks.

Hi
Did you try with only 1 processor?
Try to have a look into the log of the partel step in the tmp directory...

Hello.
Thank you for the quick reponse.
Yes, i tried with 1 pro but the error is different: command line:
>Telemac2d.py --ncsize 1 txt.cas
The error is on MPI missing command, the image of error is attached.
Next i tryed to run with 2 pro and, after the same error, the partel_T2DGEO.log in the temporary directory is empty.
Attached also this file.

Thx for your help.

Hi
First of all you have to solve the problem of mpi missing command...
On another side, you should look the partel problem...

If partel is well compiled, you could try to run it manually on the geometry file to see where the problem is...
