DYNAMICO is firstly a hydrostatic dynamical core designed for numerical consistency and scalability, and is being integrated into IPSL-CM along the current production dynamical core, LMDZ5. In the last couple of years, it has been extended to fully compressible, non hydrostatic dynamics. Planned or under development are the support of fully unstructured meshes and limited-area domains. I will outline the computational design of DYNAMICO and present some performance metrics of the dynamical core, standalone and embedded in IPSL-CM.
