Run exe file in MATLAB using multiple cores

Hi,

I am using MATLAB to run OpenSeesSP.exe. Typically, I use the below code to run OpenSees using single core and it runs in MATLAB command window

system(['OpenSeesSP ' 'fileName.tcl']);

To run OpenSeesSP using multiple cores, I use the following code. However, OpenSeesSP runs in an external cmd window

!"C:\Program Files\MPICH2\bin\mpiexec.exe" -np 5 OpenSeesSP.exe fileName.tcl &

What should I use to run OpenSeesSP with multiple cores in MATLAB command window not in an external cmd window. I tried the below line of code but it did not work.

system(['"C:\Program Files\MPICH2\bin\mpiexec.exe" -np 5 OpenSeesSP.exe' 'fileName.tcl']);

Basically, I am gonna use this command in a for loop where I need some output from OpenSeesSP to proceed with the for loop. Thus, I need MATLAB to wait until OpenSeesSP completes its analysis.

Thanks!

See here, these properties might be what you're looking for

Exe_Process.StartInfo.UseShellExecute
Exe_Process.StartInfo.CreateNoWindow

Also, try with

system(['''C:\Program Files\MPICH2\bin\mpiexec.exe'' -np 5 OpenSeesSP.exe' 'fileName.tcl']);
%        ^^                                      ^^ double apostrophee

Or OpenSeesSP.exe accepts argument for multiple cores, without running mpiexec.

Try specifiy the full path to OpenSeesSP.exe

Please explain, what "did not work" means. The details matter to understand, what the problem is.

Hi, I'm using opensees to caculate a large model BUT I found that I can't download the OpenseesSP.exe...... Could you give me a copy file or a link?

[Mario Malic]

When I checked this last time, the program was hosted on one of the University sites.

[Byron Z]

eh, do you remember any information about the site? I've found it for several weeks, and the information was little. So, maybe, I think, can you email me your OpenSeesSP-set-up file?

Thanks a lot, sin

when i click the submit bottom, i found it error:database error 111., trying everything i can do for seveal weeks and i couldn't download OpenSeesSP.exe file. that's why I'm looking for someone for emailing me the set-up file who uses this software. So, really, can you send it to me? Please, email: [e-mail]

[Walter Roberson]

I do not have the software.

Could you confirm that you went through the registration page, and were told that your registration was accepted?

[Byron Z]

when I go to the registration page, it shows not found. So I don't know weather the website is shut down.

So I really want to know that when you submit your email, what page or error you get? And can you download the software, not like me? I'm really going crazy when I calculate the model by only one core......

Hi, I'm run OpenSeesSPv2.4 with a parfor (run each model with 2 cores, and run simultaneusly 4 models). I use this code lines for run OpenSeesSP since matlab.

% Run the model.
% -------------------------------------------------------------------------
oldFolder = cd(Path_current);
command = ['mpiexec -n 2 OpenSeesSP_x64 Dynamic_Analysis.tcl'];
[status,~] = system(command); % Run OpenSees.
cd(oldFolder);

I hope that it will help you.

What is your OpenSeesSP version?, I need a current version of OpenSeesSP, at least a version that allow run a model with 6 inputs ground motion (3 translational with 3 rotational).

Bests, M.
