-The activity is based on the analysis of the NEMO single-core performance done in 2017 and will continue with the investigation of alternative coding approaches to increase the data locality of the routines identified as memory-bounded.
+The activity is based on the work started in 2017. A portable tool to extract the hardware performance counters needed for the analysis of the NEMO single-core performance has been implemented and tested on NEMO. A preliminary analysis has been done on Met Office and CMCC systems and memory-bounded routines have been identified.
+The action will continue during 2018. The following sub-actions are identified:
+
+(i) integration of the portable tool in the 4.0 release. This action is needed to extend the analysis to several architectures (Tim Graham or someone else from Met Office)
+(ii) analysis on other systems (someone from Mercator)
+(iii) investigation of alternative approaches to improve the data locality (Silvia Mocavero)
