Jean and P. Breitkopf on the use of the parallel computing for the granular dynamics [1]. The chosen parallel strategy is similar to a Domain Decomposition Method (DDM), even if the substructuring procedure is more modestly called a "box method" and does not refer explicitly to a DDM. The Domain Decomposition methods in the context of multiprocessor computations, are well established from theoretical and practical standpoints when dealing with a linear system derived from a discretization of a continuous problem [4]. %G English %2 https://hal.science/hal-00797489/document %2 https://hal.science/hal-00797489/file/Is_it_reasonable_to_split_Alart.pdf %L hal-00797489 %U https://hal.science/hal-00797489 %~ CNRS %~ LMGC %~ MIPS %~ UNIV-MONTPELLIER %~ UM-2015-2021
