Installing Ultrascan on a 64-bit AMD Opteron Cluster running CentOS 5 Linux

UltraScan "attempts to be a comprehensive data analysis tool for the hydrodynamic studies of macromolecules and macromolecular assemblies with analytical ultracentrifugation experiments."

Sounds like fun. Let's install it. Get the tarball, ignore the part of the site which uses frames and extract in a sensible place, such as /usr/local/src/ULTRASCAN (tar xvf ultrascan-9.9-888-qt-3.3.8-ix86-linux.tar.gz).

Now the fun starts

Installing NAMD 2.7b1 with CUDA on a 64-bit AMD Opteron Cluster running CentOS 5 Linux

NAMD is a parallel molecular dynamics code for large biomolecular systems. Version 2.7b1 has some advantages over 2.6 and an extensive user's guide. CUDA (Compute Unified Device Architecture) is a parallel computing architecture developed by NVIDIA providing a computing engine in NVIDIA graphics processing units or GPUs. It should make NAMD awesome, if it works.
