U_obs_op_f
v1 v2 19 19 20 20 Hint: 21 * The routine is similar to ` init_dim_obs` used for the global filters. However, with a domain-decomposed model `m_state_f` will contain parts of the state vector from neighboring model sub-domains. To make these parts accessible, some parallel communication will be necessary (The state information for a neighboring model sub-domain will be in the memory of the process that handles that sub-domain). The example implementation in `testsuite/dummymodel_1d` uses the function `MPI_AllGatherV` for this communication.21 * The routine is similar to `U_obs_op` used for the global filters.
