Harvesting graphics power for MD simulations
We discuss an implementation of molecular dynamics (MD) simulations on a
graphic processing unit (GPU) in the NVIDIA CUDA language. We tested our code
on a modern GPU, the NVIDIA GeForce 8800 GTX. Results for two MD algorithms
suitable for short-ranged and long-ranged interactions, and a congruential
shift random number generator are presented. The performance of the GPU's is
compared to their main processor counterpart. We achieve speedups of up to 80,
40 and 150 fold, respectively. With newest generation of GPU's one can run
standard MD simulations at 10^7 flops/$.Comment: 12 pages, 5 figures. Submitted to Mol. Si
A pilgrimage to gravity on GPUs
In this short review we present the developments over the last 5 decades that
have led to the use of Graphics Processing Units (GPUs) for astrophysical
simulations. Since the introduction of NVIDIA's Compute Unified Device
Architecture (CUDA) in 2007 the GPU has become a valuable tool for N-body
simulations and is so popular these days that almost all papers about high
precision N-body simulations use methods that are accelerated by GPUs. With the
GPU hardware becoming more advanced and being used for more advanced algorithms
like gravitational tree-codes we see a bright future for GPU like hardware in
computational astrophysics.Comment: To appear in: European Physical Journal "Special Topics" : "Computer

Computational Physics on Graphics Processing Units
The use of graphics processing units for scientific computations is an
emerging strategy that can significantly speed up various different algorithms.
In this review, we discuss advances made in the field of computational physics,
focusing on classical molecular dynamics, and on quantum simulations for
electronic structure calculations using the density functional theory, wave
function techniques, and quantum field theory.Comment: Proceedings of the 11th International Conference, PARA 2012,
