How do I run SU2 in parallel on windows?

Flare · January 30, 2019, 14:13

Hi everyone,

Just joined this forum and I am in the process of installing SU2 on a Windows machine.

I'm able to run the program (version 6.0.0, the latest windows release) with test cases on a single core quite easily by just running the following in the command window from the directory I have my config file in. I have set the SU2 directory environment variable and the path.

Code:

SU2_CFD incomp_NACA0012.cfg

I have installed MPI to run in parallel, and if I run the following command:

Code:

mpiexec -n 4 SU2_CFD incomp_NACA0012.cfg

I get the problem where each line is printed out in the console 4 times. The FAQ for SU2 mentions that this means MPI is not configured properly but I'm not sure where to go from there as the instructions it takes me to are for a linux system.

If anyone could point me in the right direction on how to get SU2 to run in parallel on Windows that would be fantastic.

Hi,
There are two type solution file for SU2 in Windows. You should use SU2_CFD.exe in ExecParallel folder. I think you may use sequential of it.

When I downloaded the software only the ExecSequencial folder was included. I don't see an ExecParallel folder anywhere in the source code for 6.0.0 either. Do you know where I can get ExecParallel?

Do you use w7 or w10? For w7, you are right there is no parallel solution file.

Update: I'm still stuck.

I have followed the pdf linked in this forum thread: Any Procedure to setup parallel computation?? but haven't had any luck. I still get the problem where each line is printed out once per core.

Any other suggestions? Should I try and start from scratch or just try and run it in a linux thing like cygwin?

Hello Flare,

I encountered the same problem with using [mpiexec -n 16 SU2_CFD incomp_NACA0012.cfg] and it just printed out in the console 16 times .

Any solution regarding to this problem yet?

Thanks,
best, JIM GIGI
