open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi, I am currently in the process of launching a large number of simulations.
I conducted some simulations on a cluster to see the most beneficial numbers of processors to use for this particular case and see which speedup is better for this case.

The cluster gives me two different types of time for the duration of the simulation. Real and user time, the user time is the same you can see printed by the script telemac2d.py at the end of a run. Real time is much shorter and only accounts for the time use for the algorithm.

User time accounts for MPI transfers and prints on screen. In some cases the user time its quite larger than the real one. I can not remove MPI time usage but i can lose print on screen time.

Is there a way to run telemac2d.py in silent mode as in whit no prints on screen?

So far i have change my FortranFile and commented out the lines that print this information. It seems that there would be a better way to do this.

Greetings,

Hi
It exist some KEYWORDS that manage the period of printout and also the start of printout.
So you could run on silent mode if you choose the right values for those keywords...

Hope this helps

hi, I found the keyword LISTING PRINTOUT in he manual, but it said it is not recommend to put the logical value "NO". what is the reason for this?

This keyword on logical value "NO" has the same graphic result as comment lines in the FortranFIie.

This should reduce my simulation time? I tried 2 models last night and the one whit the Silent mode took 3 extra minutes to complete the simulation.
they were 200000 time steps each under the same conditions.

Hi
I thought on LISTING PRINTOUT PERIOD and NUMBER OF FIRST TIME STEP FOR LISTING PRINTOUTS...

Your solution should also works as you cancel all listing prints except the header and the message about the end of computation...
So your result of your latest test is really strange...

Ok. Thank you.
