TELEMAC-MASCARET Forum: Telemac2D V7p2 in parallel (1/1)

Telemac2D V7p2 in parallel 6 years 2 months ago #31541

myousef

Hi there,

I am new to Telemac2D (version v7p2) and would like to use the parallel mode to speed up the computation time. I am using a Windows 7 PC.

I have referred to the manual (Section: 15. PARALLELISM), and my understanding is that the default setting of Telemac2D is to run with a single processor.

The manual also mentions the parallel input command for Telemac2D: telemac2d.py –s --ncsize=4 txt.cas, where 4 is the number of processors to be used in the simulation.

I ran it, and I waited for a few hours but nothing happened, and when I checked, the temporary file there was no update. However, in the screenshot attached, in the end, it states the file name: out_telemac2d.exe

When I clicked on the file, it opened, a new window and the simulations started. Is this the correct way to run some processors in parallel? I used eight processors; however, I believe there is something I am missing here because it took longer than one processor only.

Any help is greatly appreciated.

Thank you
M Yousef

myousef	Hi again, I managed to do it, just in case someone else runs into the same issue in the future, here are the steps I followed: In a cmd window type the following commands: 1. smpd -install 2. mpiexec -remove 3. mpiexec -register (with your windows login username and password) 4. run simulation in parallel

Hi everyone,

Please could they help me, Because I have a problem when I running TELEMAC-2D I am not sure maybe is the meshing.
Please explained what happen.

Thank you
