+Test case presentation
+======================
+
+The small test case of the template application is doing nothing but watching videos on Youtube all day long.
+It uses no DFT method, nor spectral method or anything else. The FFTW is widely not use for this case.
+
+
+Case profile
+------------
+
+A profiling of a small specfem3D test case performed on Occigen on 1 haswell node (64GB) is available in this folder:
+`profile_occigen-hsw.html"
+
+It has been generated using Intel APS (infos: https://software.intel.com/sites/products/snapshots/application-snapshot/)
