open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello Christophe.

In fact, it was a question of « power options » under windows. I was in « energy economy » and the clock frequency was reduced to 1/3 of the maximum frequency.
But, I had a problem : when I set to « normal » or « high performances » mode, windows switched automatically to « energy economy » mode. It took me some times to understand why : it was a pre-installed Samsung utility which imposed the « energy economy » by default even if I switched to another mode.
Well, I have uninstalled this utility and I can now enjoy my full CPU’s capacities

Hope this helps you.

Hello everyone,

I just finished compiling Telemac in parallel mode and run a simulation using the following command:

telemac3d.py --ncsize=4 D:\.................\cas.cas

-- ncsize = 4 : to use my 4 processors for the computation.

I had what is indicated on the picture attached.
left: the simulation stops without error message.
right: temporary files created for simulation.

Thank you in advance ...


Bonjour à tous,

je viens de terminer la compilation de Telemac en mode parallèle et de lancer une simulation en utilisant la commande suivante:

telemac3d.py --ncsize=4 D:\.................\cas.cas

--ncsize=4 : pour lancer le calcul sur mes 4 processeurs

j'ai eu ce qui est indiquer sur l'image en pièce jointe.

à gauche la simulation qui s’arrête sans message d'erreur.
à droite les fichiers temporaires créés pour la simulation.

Merci par avance...

Hi
For me the simulation didn't stop. I think MPIEXEC waiting for something.
Try to run in the temp folder the mpiexec command manually.

Hi,

Thank you for your replay Mr. Coulet.
But how to run the mpiexec command manually???

Regards.

Just by retyping the last command line in a dos command windows!

Nothing happens Mr. COULET except that I lost the permesion to write anything else.

I attach the screenshot after writing the command I wrote before...

No, that's not my demand.
After trying to run telemac3d normally, you abord the job CTRL+C
Then go into the temp directory and manually type mpiexec ....

Regards

But I don't have mpiexec in the temp directory, I have just what appears in the folder to the right of the picture I attached in the previous post...

thank you in advance.

Yes
but try to reflect just a little bit before posting!

I wrote that you have to type the LAST COMMAND LINE of the python script.

When i wrote "manually type mpiexec ..." this is for the example.

So, as it seems to be very complicated, in the temp directory you should manually enter the following command:

Hi Massinissa,

If you have MPICH2, you can try what is explained in the post #6051 from topic www.opentelemac.org/index.php/kunena/2-w...n-11-1?start=10#6051
It helps me for the pb with mpiexec.
If it doesn't solve your trouble, there's many topics about mpiexec in the forum and I'm sure you will find a solution.
Best regards

Olivier
