    25 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. 
     25The 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. 
     26The action will continue during 2018. The following sub-actions are identified: 
     27 
     28(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) 
     29(ii) analysis on other systems (someone from Mercator) 
     30(iii) investigation of alternative approaches to improve the data locality (Silvia Mocavero)
