Different strategies will be evaluated, as reducing internode communication time and frequency, limiting the communication overhead in general, improving the balance between the number of messages and the packet size as well as studying the optimal distribution of the model subdomains according to the computing resources and network topology. 30 25 31 26 === Implementation 32 33 {{{#!box width=35em help34 Describe flow chart of the changes in the code. \\35 List the Fortran modules and subroutines to be created/edited/deleted. \\36 Detailed list of new variables to be defined (including namelists), \\37 give for each the chosen name and description wrt coding rules.38 }}}39 27 40 28 ''...'' 41 29 42 30 === Documentation updates 43 44 {{{#!box width=55em help45 Using previous parts, define the main changes to be done in the NEMO literature46 (manuals, guide, web pages, …).47 }}}48 31 49 32 ''...''
