Automated parallelizing not working with large matrixes

Hi

I have a code in fortran that calculates eigenvectors and eigenfunctions of matrix and process the results. I use the ifort with the -mkl compilation, the code runs in parallel for an square matrix (N,N) when N is less than 100 (more or less) but when I try larger matrixes N>300 it only runs as one thread. 

Any help?

Regards, Eric

You might get more useful response on the appropriate ifort forum. Maybe you want the mkl parallel without the qparallel.
