Which version of NAMD should I download?

The versions of NAMD below are distinguished first by OS, followed by the type of network interface, and whether or not CUDA is supported. If you are installing NAMD on a standalone workstation, we recommend downloading Linux-x86_64-multicore for Linux or Win64 for Windows. If your workstation has a CUDA-capable GPU, you should try downloading Linux-x86_64-multicore-CUDA or Win64-CUDA. If you wish to run multi-copy algorithms, such as replica-exchange MD, you should try the 'netlrts' builds, such as Linux-x86_64-netlrts or Linux-x86_64-netlrts-smp-CUDA.

If you have a modern NVIDIA GPU (Pascal or newer), you might also be interested to try the new version 3.0 alpha, which includes the option of running standard MD simulations entirely on a single GPU for much faster performance. See the support web page for more information.
