  RUMD is a general purpose, high-performance molecular dynamics (MD)
simulation package running on graphical processing units (GPU's). RUMD
addresses the challenge of utilizing the many-core nature of modern GPU
hardware when simulating small to medium system sizes (roughly from a few
thousand up to hundred thousand particles). It has a performance that is
comparable to other GPU-MD codes at large system sizes and substantially better
at smaller sizes.RUMD is open-source and consists of a library written in C++
and the CUDA extension to C, an easy-to-use Python interface, and a set of
tools for set-up and post-simulation data analysis. The paper describes RUMD's
main features, optimizations and performance benchmarks.
