error in coupled model initialization

Context

  • Branches impacted: branch_4.2 and main
  • Dependencies: AGRIF OASIS XIOS

Analysis

There are 2 potential issues with the initialization of the coupled model.

  1. The first issue is a potential dead lock at initialization when using OASIS and XIOS in several components of a coupled model. This issue was first reported here : https://forge.ipsl.jussieu.fr/nemo/ticket/2458 Now that we are using XIOS-trunk in branch_4.2 and main, we should implement it. Detail explanations are given in comments 4 if the above mentioned ticket this pdf
  2. The second issue rises when using AGRIF and OASIS. Again it is a long standing issue that was not properly fixed.

Fix

  • For issue (1) use the nex xios function: xios_oasis_enddef
  • For issue (2) check if we are Agrif_Root() or not
