Installation of MVAPICH2 for Different Compilers

Submitted by lev_lafayette on Mon, 07/12/2010 - 23:49

MVAPICH and MVAPICH2 is an implementation of MPI for computing systems and servers using InfiniBand, 10GigE/iWARP and RoCE & etc networking technologies.

Installation consists of downloading the tarball into an appropriate directory, extracting it, loading the enviroment variable modules, using of some previously established configuration files, runnig make and make install, and establishing the symbolic links. Note that MVAPICH and MVAPICH2 are entirely different products.

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

Installing MrBayes for MPI and 64-bit

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.

Installing a GUI for EGSnrc Usercodes

Submitted by lev_lafayette on Fri, 04/16/2010 - 01:52

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/
