Multi-core CPUs and GPU Acceleration

VMD makes full use of multi-core processors and multiple GPUs for acceleration of the most computationally demanding visualization and analysis tasks. Multi-core CPUs accelerate features including interactive MD, bond determination, ``within'' atom selections and derivatives, radial distribution functions, and high quality renderings using the ``Tachyon'' and ``TachyonInternal'' ray tracing features. VMD also supports GPU acceleration using CUDA, and takes advantage of both multi-core CPUs and GPUs for acceleration of electrostatics (i.e. ``volmap coulomb'', and ``volmap coulombmsm''), implicit ligand sampling (i.e. ``volmap ils''), and computation and rendering of molecular orbitals.
