Tuning and Analysis Utilities (TAU) is a program and performance analysis tool for high-performance parallel and distributed computing with a suite of tools for static and dynamic analysis of programs written in C, C++, FORTRAN 77/90, Python, High Performance FORTRAN, and Java.
You'll also need the Program Database Toolkit (PDT), also available from the same location. Let's install that first. You'll need to set your environment variables. You use modules, right?
module load gcc/4.4.4
modulel load openmpi-gcc/1.3.4

Let the home page describe what it is about (in the worst possible English): "MrBayes is a program for the Bayesian estimation of phylogeny. Bayesian inference of phylogeny is based upon a quantity called the posterior probability distribution of trees, which is the probability of a tree conditioned on the observations. The conditioning is accomplished using Bayes's theorem.

Anyone who does even a modicum of web developments finds themselves taking tabled text, sometimes in the most horrid format, and having to introduce it into some sort of clean html.

A previous installation of EGSnrc was based around a command-line option. There is also a GUI interface for EGSnrc usercodes which is quite trivial to install and run.
Ensure that your environment variables for EGSnrc are loaded (e.g.,
module load egs). For example
set HEN_HOUSE /usr/local/EGSnrc/$version/
set my_machine x86_64-unknown-linux-gnu-pgf77
setenv EGS_HOME /home/$USER/egsnrc/

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.

Desmond is a software package developed at D.E. Shaw Research to perform high-speed molecular dynamics simulations of biological systems on parallel systems. Desmond and its source code are available without cost for non-commercial use by universities and other not-for-profit research institutions.

LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) is used to model atoms or as a parallel particle simulator at the atomic, meso, or continuum scale. It has potentials for soft materials (biomolecules, polymers) and solid-state materials (metals, semiconductors) and coarse-grained or mesoscopic systems.
I'm surprised I haven't documented this in the past, because I've installed it plenty of times. Nevertheless here's how it goes.

For a variety of reasons, you may wish to upgrade your Debian/Ubuntu or similar system without going through the normal process of a distribution update. Perhaps you are, for example, moving to entirely new hardware. Obviously you want to keep the data in your home directory; but you may also wish to keep the various packages you have previously downloaded. The following is some simple steps to make your life easier.

A user visited with what at first appeared to be a minor problem. Previously we had installed Fluent CFD on their Macintosh system running Ubuntu but they particularly wanted to run Gambit as well, which does primarily the design modelling and meshing transition. Licenses had been received and from this point on it would seem to be a fairly trivial task.
