Preliminary results for parallel implementation of the DEM algorithm on a MIMD distributed-memory type architecture are modest and the characteristics of the performance are considered to be dependent on a number of factors: number of particles, number of boxes (internal gridding), geometry of the compacted particles, mechanical of the particles, and the frequency of input and output. We expect to formulate this dependency so that more improvements can be done to the speedup and efficiency of the parallel code. Also, test cases with larger number of particles will be performed on a higher number of processors.
