The PI is responsible to closely follow the progress of the action, and especially to contact NEMO project manager if the delay on preview (or review) are longer than the 2 weeks expected.
Summary
Analysis of scalability improvement using MPI3 new communications (e.g. collective neighbours communications) instead of point to point communications.
ticket: #2011
Preview
Mirek Andrejczuk Plan outlined in ticket #2011 is OK. Most likely changes to the code will be limited to LBC/lib_mpp.F90. I'm happy to test the changes in MO operational configurations. May be worth considering implementation in which changing the number of halo points is easy.
