New URL for NEMO forge!   http://forge.nemo-ocean.eu

Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.

    3333=== Detached Mode 
    3434In detached mode the XIOS executable is executed on separate cores from the NEMO model. This is the recommended method for using XIOS for realistic model runs. To use this mode set `using_server` to `true` at 
    35 the bottom of the `iodef.xml` file. Make sure there is a copy (or link to) your XIOS executable in the working directory and in your job submission script allocate processors to XIOS.

    3741=== Attached Mode 
    38 In attached mode XIOS runs on each of the cores used by NEMO. This method is less efficient than the detached mode but can be more convenient for testing or with small configurations. To activate this mode simply set `using_server` to false in the `iodef.xml` file and don't allocate any cores to XIOS. Note that due to the different domain decompositions between XIOS and NEMO if the total number of cores is larger than the number of grid points in the j direction then the model run will fail.
