     56The regular tests use a rather small configuration with a simulated model. This model is also included in the test suite of the downloadable PDAF package.
     57In addition, the scalability of PDAF has been examined with a real implementation with the finite element ocean model (FEOM, Danilov et al., A finite-element ocean model: Principles and evaluation. Ocean Modeling 6 (2004) 125-150). In these tests up to 4800 processor cores of a supercomputer have been used.
     58To examine PDAF's behavior with large-scale cases, experiments with the simulated model have been performed in which the state dimension was 10^9^. An observation vector of size 10^7^ was assimilated. For these experiments, the computations used 256 processor cores.
