    initial v1  
    1 With the latest commit this branch works with Agrif. Performance of the read interface is far from perfect for high resolution (GO6, ORCA12 - MetOffice) configurations. There are also failures when reading restart for large number of processors. Reading functionality works when domain is decomposed using up to 60x60 processors (with land suppression on), but fails when 70x70 (or more) is used. For ORCA25 XIOS read interface works fine up to 1440 processors, but is slower than reading single file restart with default NEMO interface.

    33For a single restart file XIOS can almost match default NEMO read functionality, but the interface is slower than reading multiple restart files (each processor is reading its own domain).
