S3.3-h High parallelisation on new plateforms


Last edited Timestamp?

This page gives a non exhaustive description of the work (to be) done to optimise the code for massively parallele processing
There main strategies are follows :

  • reduce the number of communication in the baroclinic part of the code
  • generalise the time-splitting solver (educe the number of communication in the barotropic part of the code)
  • re-activate the extended halo (switch from 1 to 2 overlap row/column)

1. Reduce the number of communication (baroclinic part)

1.1 Vertical mixing

Suppression of avmu and avmv arrays.

2. Reduce the number of communication (barotropic part)


3. Extended overlap halos
