Issues related with parallel computations

Da MeteOceanWiki.

After installing the "Automatic Installer" in Windows (Installation using "Auto Installer") you get two different prompts: one for scalar computations and another for parallel computations.

The following instructions were carried aout on version v7p0 of open-telemac.

Open the parallel prompt and run

   compileTELEMAC.py

If it works you have just accomplished your job, otherwise go on reading.

Once you open the prompt for parallel computations you can run your model in the usual way (Run a case). However, the simulation will start only if the appropriate binaries have been compiled and are present in the appropriate folder inside the path "v7p0/builds". This was not my case.

In order to solve this issue take a look at the following links:

http://www.opentelemac.org/index.php/kunena/2-windows-version/7980-telemac-parallel#17589

The procedure I followed is this:

1) download the file "systel.parallel.cfg" from the link above and save it into the folder "v7p0/configs";

2) open the file and, in case, change the root-path;

3) go inside the folder builds and run in the parallel prompt

    compileTELEMAC.py -f path_to_your_folder/v7p0/configs/systel.parallel.cfg -c wing64mpi

4) everything should be compiled;

5) now yoy can run in parallel using the command

    artemis.py -f path_to_your_folder/v7p0/configs/systel.parallel.cfg your_file.cas
