4. Multi-processor computing

When using multiple processors, the model data must be replicated to all processors involved in the calculation using the DISTRIBUTION keyword from the AFFE_MODELE command

MODEL = AFFE_MODELE (...

DISTRIBUTION =_F (METHODE =' CENTRALISE '))

The calculation can then be performed on several processors. Attention, as all processors perform the same operations, there is no calculation gain for the stage of eliminating Lagrange multipliers. The advantage is to then perform a modal calculation on several processors.
