For intel compiler 2013 you will probably need to refer to the MKL link advisor since the -qopenmp-link-static will not work.

Now regarding the Parmetis, it is highly likely that the compiled static library provided is from a newer version of c compiler and this is why you might experience this issue. I would suggest that you download the Parmetis (http://glaros.dtc.umn.edu/gkhome/metis/parmetis/download) compile from source following the instructions and then following compilation copying both the libparmetis and libmetis from their respective directories in your code directory.

Let me know if this works.

I try the version from parmetis-4.0.1.tar.gz to parmetis-4.0rc1.tar.gz (http://glaros.dtc.umn.edu/gkhome/fsroot/sw/parmetis/OLD), but it doesn't work and it encounters the same problem. I wonder where the problem is. ![Uploading mmexport1639583868048.png…]()
