  * More radical change : the working space is build dynamically. This solves limitation 2.
 
-==== Timing ====
-==== Auto-assignement ====
-==== Dynamic dynamic memory ====
+==== 1- Timing ====
+
+This functionality doesn't aim to replace advanced software used for optimisation but:
+ * to give a rough idea of performance (CPU and elapsed)
+ * use the same tools and format on all computers( fortran intrinsec CPU_TIME and WMPI_TIME)
+It is bases on a linked chain of informations to be able to add dynamically new sections and add sub-sections[[BR]]
+Implementation:
+ * CALL timing_init in nemogcm_init
+ * CALL timing_finalize at the end of nemoggcm
+ * at the end of step, IF( kt == nit000) CALL timing_reset (once the list of varibles has been built)
+ * in each routine to instrument : CALL timing_start('NAME')    CALL timing_stop('NAME')
+Imbricated sub-sections are allowed and their time is then subtracted from the mother section unless the call of timing of the section is done in the following way CALL timing_start('NAME')    CALL timing_stop('NAME',section)
