Abstract of GEM Analysis for Computational Science

• We briefly discuss why GEM is interesting

• We state the computational problem for GEM and analyze parallel computing issues for key steps

• We map into a particle dynamics analogy using Green’s function formalism and consider O(N2) cut-off O(N) and fast multipole methods

• We go in detail through the fast multipole method

• We expect object oriented approaches to be very important booth at language level and in using technologies like CORBA to integrate world-wide collaboration, simulations and experiments.
