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.

Underworld on a 64 bit Opteron Fedora Core 5 Cluster

Underworld is a "3D-parallel geodynamic modelling framework capable of deriving viscous / viscoplastic thermal, chemical and thermochemical models consistent with tectonic processes, such as mantle convection and lithospheric deformation over long time scales.... Underworld utilises a Lagrangian particle-in-cell finite element scheme (the prototype of which is the Ellipsis code), and is visualised using gLucifer."
