Problem with parallel mode V7P0 8 years 3 months ago #23510

yugi OFFLINE openTELEMAC Guru Posts: 851 Thank you received: 244	I think i might see the solution. Could you post your configuration file (C:\opentelemac-mascaret\v7p1\configs\systelGF64_ para.cfg) and the steering file that you launch not the one in the temporary folder? Thanks

Did you removed your executable before running the case ?
It should be named main_v7p1_PD13p0.exe.
If not remove it and rerun the case.

If that still does not work could you try using the following systel.cfg file and recompile the code with it (use option --clean)

Chris C.	Deleting the .exe file seemed to have solved the issue! Now I get another error (SIGSEV - segmentation fault) but will into it... Many thanks for your help!

yugi OFFLINE openTELEMAC Guru Posts: 851 Thank you received: 244	The problem was that the compiled file you had was compiled with a sequential configuration hence the error in parallel.

josekdiaz OFFLINE Expert Boarder Posts: 161 Thank you received: 48	Dear Yoann, A side question, and maybe a little off-topic, when running consecutive cases in the same folder (and slightly modified cas inbetween runs) does telemac use the exe from the previous run or compiles it again and overwrites the file? Does it behave the same way in both windows and linux? Regards, José D.

yugi OFFLINE openTELEMAC Guru Posts: 851 Thank you received: 244	If i am not mistaken he only recompiles if the Fortran file is more recent than the executable. Hope it helps.
