This model is also included in the test suite of the downloadable PDAF package. 62 62 In addition, the scalability of PDAF was 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 (see [PublicationsandPresentations Nerger and Hiller (2013)]). 63 To examine PDAF's behavior with large-scale cases, experiments with the simulated model have been performed. By now the biggest case had a state dimension of 6.0^.^10^10^. An observation vector of size 1.2^.^10^9^ was assimilated. For these experiments, the computations used 12000 processor cores. In this case, the distributed ensemble array occupied about 2 GBytes of memory for each core. The overall largest number of processes with which PDAF was validated was 16800 processor cores.63 To examine PDAF's behavior with large-scale cases, experiments with the simulated model have been performed. By now the biggest case had a state dimension of 1.2^.^10^11^. An observation vector of size 2.4^.^10^9^ was assimilated. For these experiments, the computations used 12000 processor cores. In this case, the distributed ensemble array occupied about 2 GBytes of memory for each core. The overall largest number of processes with which PDAF was validated was 16800 processor cores.
