Maybe you want the mkl parallel without the qparallel.

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&gt;300 it only runs as one thread.&nbsp;</P> <P>Any help?</P> <P>Regards, Eric</P> <P>&nbsp;</P> Wed, 30 Dec 2015 14:49:41 GMT https://community.intel.com/t5/Intel-Moderncode-for-Parallel/Automated-parallelizing-not-working-with-large-matrixes/m-p/1068209#M6952 suarez__eric 2015-12-30T14:49:41Z https://community.intel.com/t5/Intel-Moderncode-for-Parallel/Automated-parallelizing-not-working-with-large-matrixes/m-p/1068210#M6953 You might get more useful response on the appropriate ifort forum.
