Towards Understanding Optimal Load-Balancing of Heterogeneous Short-Range Molecular Dynamics

Adaptive grid implementation for parallel continuum mechanics methods in particle simulations

“…Sec. 2.1.3 [104,208]. We calculate the partition-weight of a cell c k in the FCT w fct i (c k ) as weighted sum over all input grids g,…”

Towards Informed Partitioning for Load Balancing: a Proof-of-Concept

“…Note that not every particles simulation suffers from load imbalance created by the particle migration. For example, as suggested by [13], in Brownian motions, the migration of particles does not create load imbalance over time because there are no preferred direction for the particles. Hence, there is no particular gathering of particles in a subset of processing elements.…”

“…Recently, Hirschmann et al [13] studied the behavior of standard partitioning techniques in particle simulation using a load dynamic metric. This metric uses the norm of the difference between the load distribution at two iterations and shows that load balancing techniques are not equal with respect to the load dynamic (i.e., load imbalance growth).…”
