CUDA Spotlight
GPU-Accelerated Molecular Dynamics
This week’s spotlight is on Dr. Ross Walker, assistant research professor with the San Diego Supercomputer Center (SDSC) at UC San Diego and adjunct assistant professor in the Department of Chemistry and Biochemistry at UC San Diego.

Dr. Walker is a lead developer of AMBER (Assisted Model Building with Energy Refinement), a Molecular Dynamics (MD) software package for the simulation of biomolecules. A new update of AMBER, focusing on improved GPU acceleration, was recently made available to the public.
Ross Walker
NVIDIA: Ross, tell us about the AMBER news announcement.
Ross: The announcement concerns a large scale update to the GPU acceleration support in AMBER. This is something we have been working on for the last nine months with funding from the National Science Foundation’s Scientific Software Infrastructure and Innovation program, in close collaboration with NVIDIA.
NVIDIA: What are potential applications of GPU-accelerated AMBER?
Ross: The latest update to GPU-accelerated AMBER provides performance that was previously unattainable, even with the fastest supercomputers. Thus we are now in a realm where for the first time we are talking about increasing capability and not just GPU acceleration. This widens the scope for the types of scientific questions one can attempt to solve.
NVIDIA: What kind of advantages have you achieved with CUDA?
Ross: I cannot begin to do justice to the revolution that GPU acceleration through CUDA is having on Molecular Dynamics. The GPU acceleration of MD through CUDA is, for the first time, making it possible for scientists to ‘experiment’ computationally. With our latest update, the performance of the code on a single Tesla M2090 GPU outstrips that achievable on 192 nodes of a Cray XT5 supercomputer.
NVIDIA: When you think about the future of Molecular Dynamics, what excites you the most?
Ross: We are only just beginning to scratch the surface in the types of questions we can ask with Molecular Dynamics. Traditionally it has been too slow and computationally expensive to make a significant impact in the drug discovery process but with GPU acceleration we are now at a point where the accuracy of MD approaches is no longer limited by the amount of sampling that can be done.
