How to Exit Parallel Computing in OpenSeesMP

[nupassin]

Dear All,

I am using the OpenSeesMP. In the Main.tcl script, I called several Procedure.tcl using the parellel computing, after which I want to end the parallel mission because the other commends in Main.tcl need to be done in seriel. Is there any commend to transfer parallel to serial in OpenSeesMP? Or how can I end and restart parallel mission again and again?

Thank you!

no .. but just end all but 1 processor, e.g.

# do parallel stuff
if {$myID == 0} {
# do sequential stuff
}

Thank you so much, Frank!
I solved the problems follow your ex7.tcl, that's a quite useful example.

Could you tell me where can I download the complete example about parallel computing in OpenSeesMP?

If you want to run parallel computations multiple times within the same script, you may need to reset the MPI environment between each parallel run. However, this approach can be complex and may not be directly supported by OpenSeesMP. It's generally simpler to structure your script to perform parallel and serial computations in separate runs.
