Figure 1From: Multi-dimensional characterization of electrostatic surface potential computation on graphics processorsIllustration of the hierarchical charge partitioning (HCP) of biomolecular structures. In this illustration a biomolecular structure is partitioned into multiple hierarchical levels components based on the natural organization of biomolecules. The charge distribution of distant components are approximated by a small number of charges, while nearby atoms are treated exactly.Back to article page
