 As first step, the portability of NEMO diagnostic calculations to GPUs has been analyzed, exploring how to adapt these regions from the current MPI implementation to the CUDA paradigm. A toy model has been created to perform preliminary tests, that were done using the dia_hsb diagnostic. The code itself is executed 50x faster than in a single CPU but the data transfer to and from GPU is the main bottleneck. 
 
-We are working on the asynchronous strategy in order to hide all communications among GPU/CPU. We also plan to increase the efficiency of the overall solution, by mitigating the impact of the offloaded data and extending our approach to the rest of the diagnostics. 
+The plan for the next months is to work on removing the CPU/GPU communications from the critical path, by using an asynchronous method or parallelizing them with a computation phase. At the same point the efficiency of the overall solution will be improved, by mitigating the impact of the offloaded data.
+
+The last step will be to extend this approach to the rest of the diagnostics.
