Distributed computation
(NEMO model)

The computation of these solutions requires considerable informatic resources. The figure shows the division into subdomains of the DRAKKAR global ocean model grid at a 1/4° résolution (1442 x 1021 x 46 nodes) in order to distribute the computation (3400 CPU hours, for one year of simulation) over 186 processors of one of the IDRIS supercomputers (IBM Power4).
