Par contre, si vous avez compilé un code sur un système utilisant des processeurs Intel et que vous avez utilisé une ou des options <tt>-xXXXX</tt>, telle que <tt>-xCORE-AVX2</tt>, les applications compilées ne fonctionneront pas sur Narval, car les compilateurs Intel ajoutent des instructions supplémentaires pour vérifier que le processeur utilisé est un produit Intel. Cela étant dit, sur Narval, l'option <tt>-xHOST</tt> devient équivalente à <tt>-march=core-avx2</tt>. | Par contre, si vous avez compilé un code sur un système utilisant des processeurs Intel et que vous avez utilisé une ou des options <tt>-xXXXX</tt>, telle que <tt>-xCORE-AVX2</tt>, les applications compilées ne fonctionneront pas sur Narval, car les compilateurs Intel ajoutent des instructions supplémentaires pour vérifier que le processeur utilisé est un produit Intel.

The Intel MKL library works with AMD processors, although not in an optimal way. We are presently examining the option of using the [https://github.com/mpimd-csc/flexiblas FlexiBLAS] library when installing the next software versions; this would automatically load the appropriate library, depending on the processor's provider. If you think that your code is espacially sensitive to the performance of BLAS or LAPACK, please report this to [[Technical support]]. | The Intel MKL library works with AMD processors, although not in an optimal way.
