| Abstract: | In this paper, parallel implementation issues of commonly used marking strategies in adaptive finite element computations are discussed. The interface function which realizes these strategies in the adaptive finite element toolbox PHG 1]is presented. An efficient parallel algorithm for a class of strategies whose parallel implementation is non trivial, such as the MNS strategy and the mostly used GERS strategy, is presented. |
