Hi,

I am new to the subject of multithread. I have codes in Intel fortran in which i also call static libraries. I want to rum my code on multi core (under windows) system. where can i find some clear examples or other usefull matrials to learn how to run my code using multi core.

Regards,
Amir

Intel Fortran has a -parallel (auto-parallel) option for generation of OpenMP code. The next step is to improve on that by explicit OpenMP. Clearness of examples might be in the eye of the beholder. I show some where OpenMP does or does not work:

I used to have a white-paper on this, but it was taken down.

http://openmp.org/wp/resources/#Tutorials is a good place to start.

A paper I found helpfull with modern fortran and openMP can be found here:

I think https://computing.llnl.gov/tutorials/openMP demonstrates well about OpenMP.

Plz do refer.
