Computing outside Saclay

Due to the complexity and the huge size of the numerical calculations, major COAST simulations are performed on the biggest supercomputers in Europe.
Members of COAST are using 4 supercomputers in France and Germany:

Computing at Saclay

COAST team has his own computers at Saclay; there are dedicated computers, smaller size than those available in major centers of national and European calculation.
Their role is to develop, test and validate computer codes, but they also help to set up a first exploratory phase often research projects.
Also, it is necessary to dispose of machines for the post-processing and visualization, which must be powerful, for example, load the data in memory.
