open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi everyone

I have run some cases with TOMAWAC, but runs were very slow. So I want to test parallel installation in my computer, hopefully by that way, it runs faster.

Could you tell me how to test parallelism in my computer? e.g which codes? I am sure it is not like scalar computation: xxx.py yyy.cas

Best Regards

Hi Huy,

First of all you need to compile a version of telemac with parallel libraries. If that is already done, then all you need is to specify the parallel configuration using the "-c" flag and then add the "--ncsize=x" at the command, where x is the number of processors you need to run the computation on.

Thanks Costas.

So, for example, I have to type: telemac2d.py --ncsize=5 t2dmodel.cas? (my computer has 5 processors, and t2dmodel.cas is my steering file)

And you have mentioned about ''-c" flag, is it located in the python directory or MPI?

Thanks & Best Regards

Huy

Hello Huy,

The "-c" is the option to specify the parallel configuration in the systel.cfg file. For example if the parallel configuration in your systel file is "wintelmpi" the command would be:Do you have a parallel configuration compiled? You can post your systel.cfg file if you are not sure.

Hi Costas,

This my the file I take from C:\opentelemac-mascaret\v7p0\configs

Thanks & Best Regards

Your only configuration is a parallel one. So I guess the "-c" flag is optional. Does this command work for you?Costas

Dear Costas,

Here is the screen after I typed the command. Is it working? What do I do next?

It seems to run OK. You can redirect the console output to a txt file so that it is easier to post. Use this command and post the file:Costas

Dear Costas,

I suspect it does not work

When I typed that command, the model run, keep pending for long time. So I have to stop it.

How can I do?

Thanks and Best Regards

Everything looks OK except the computation. Have you registered your credentials with mpiexec/smpd service?
