Hello:
Which is the best way to tell the mex function to compile using
OpenMP? I have a mex function for Matlab and I can compile it for
Octave without problems using
mex -O3 myfunc.c
If I use
mex -O3 -fopenmp myfunc.c
I obtain no errors nor warnings and the mex function is generated, but
the code not runs in parallel as I can check using the htop utility.
How is the correct way to use OpenMP in mex files in Octave?
Thanks

The tsa package by Alois Schloegl seems to make use of OpenMP. You can take a look at his Makefile [1] to see what he did. Somehow "-lgomp" is linked, but I don't know the impact of it. Additionally, if you run
mex -v
you can get verbose information of what is done by Octave.
