This page contains the files needed to install and run Hex version 6.1. This version (24 April 2010) fixes some bugs in the previous major release (6.0). Version 6.0 and higher provides parallelised docking calculations on all hardware (previously only Linux) and GPU-accelerated calculations on Nvidia graphics cards on Windows, Linux, and Intel-Mac. Binaries compiled for Nvidia GPUs have "cuda" in their name.
For Windows-XP, download and run the self-installer hex-6b-win.exe. These are 32-bit programs, but they should run on 64-bit Windows systems.
Similarly for Intel-Mac, download and open the disc image hex-6b-Intel-Mac.dmg. For PowerPC Macs, download hex-6b-PPC-Mac.dmg.
For Linux, download the installation script hex_setup.bin and select one gzipped tar file (.tgz) which most closely corresponds to your system. The Linux binaries are labelled according to the Linux version the were built on: "lnx" means 32-bit Linux. "x64" means 64-bit Linux.
Please read the README file first. The basic installation includes a Manual and some examples. A more extensive list of examples is provided in the Hex Home Page.
The Linux and Mac CUDA versions assume that you have installed version 2.3 of the CUDA driver and run-time libraries in standard places (e.g. /usr/local/cuda on Linux and IntelMac). CUDA is available here: http://www.nvidia.com/object/cuda_get.html
On Windows, Hex uses a cache directory in "C:\Program Files\Hex 6.1\cache". On windows 7, this directory is write-projected by default. For best performance, this directory should be write-enabled for all users: right-click this folder and select the Security Tab. Then select Users, and click Edit to enable Write access.
The Windows version has not been tested on Vista.
