 === Description
 
+The use of mixed precision can provide a substantial speed-up for models in which the numerical precision has been overengineered. This speedup can come as a result of improvements in both computing and memory efficiency.
+
 This action is a follow up from HPC-08_Mixed_precision in 2018 WP. It was linked to two tickets (#2039 and #2040), that were respectively devoted to the assessment and implementation of Mixed Precision in NEMO. After the evaluation stage has been completed (together with the preparation of the necessary tools to do the mentioned assessment and the implementation), this year will be time for the implementation.
 
 Oriol Tintó (oriol.tinto@bsc.es) is the Principal Investigator for the whole task. ECMWF is a collaborator for this phase and will have a principal role on the validation in coupled simulations.
 
+The analysis procedure is documented in the following publication:

 === Implementation
 
-a) BSC developing a prototype based on NEMO 4.0.1; Further testing done at ECMWF with this version.  
+The implementation will follow the steps below:

+a) BSC developing a prototype based on NEMO 4.0.1; Further testing done at ECMWF with this version. At this stage the prototype is ready to test.
 
 b) Provide demonstrator for NEMO ST (how? => Scientific Publication, Branch in NEMO rep.) (BSC)
