Installing and Testing Valgrind on Linux

Valgrind is an instrumentation framework for building dynamic analysis tools. Which is a fancy way of saying that it's a debugging suite that automatically detects many memory management and threading bugs, which is a very good thing. Valgrind can handle dynamically generated code, so long as none of the generated code is later overwritten by other generated code. It can also perform detailed profiling to help speed up your programs. It comes with extensive documentation.

Installing MATLAB DCS/PCT on a Linux Cluster with PBS and TORQUE

MATLAB is a numerical computing environment allowing matrix manipulation, plotting of functions and data, implementation of algorithms, and high-level programming language. Typically it is run on desktop installs, which is quite problematic if one is doing a large computational problem.

Minor Issues in Installing the NCDF Libary Package for R

It seemed a trivial request, and once you've realised a couple of minor issues it is; install the NCDF library, a common scientific data format, for R, the well-known statistics software.

There is a usual way to install a package in R. Simply load the program and run the install.packages function; but this didn't quite work.


Forking Mandriva and Poor Management versus Competent Technology

There have been two fairly significant forks in the Linux world in the past few weeks; one is a large number of the developers of Mandriva now concentrating on on that technology under the new title Mageia. As advocates of that this new Linux distribution state: People working on it just do not want to be dependent on the economic fluctuations and erratic, unexplained strategic moves of the company..

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

CGAL (Computational Geometry Algorithms Library) provides efficient and reliable geometric algorithms in the form of a C++ library data structures and algorithms for triangulations, Voronoi diagrams, polygons and polyhedra, arrangements of curves and their applications, mesh generation, geometry processing, subdivision and parameterization, as well as estimation of local differential properties, and approximation of ridges and umbilics, alpha shapes, convex hull algorithms, search structures , interpolation, shape analysis, fitting, and distances, and kinetic

Vive la différence! L'affaire du foulard

Much has been made of the fact that France, the has banned the burqa, l'affaire du voile, with the exception of places of worship. Earlier in the year a law was passed that scarves covering the face were banned in schools and hospitals, as well as on public transport. Women, who violate this requirement will be fined €150 Euros and given a course of lectures on the basics of the secular foundations of the French Republic. Men, who force women to wear burqa, will face up to a year in prison.

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

Open MPI is a message passing interface that combines the merger of three major MPI implementations (FT-MPI, LA-MPI, and LAM/MPI) to create a complete MPI-2 implementation. MPI is a language-independent communications protocol used to program parallel computers.

Linux; It's Better and It's Free

The following was written in my capacity as President of Linux Users of Victoria for a community group newsletter with minimal familiarity with computer systems.

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

Mono is used to develop an Ecma standard compliant, .NET-compatible set of tools, including a C# compiler and a Common Language Runtime.

To install change to the appropriate directory. Download from Novell. Extract in the sensible place. Change to the extracted directory, check then run the sample config and run make, make install and make check. After this create a module for the environment variables and logout.

cd /usr/local/src/MONO/
tar xvf mono-2.8.tar.bz2
make install
make check

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

BigDFT is a Density Functional Theory (DFT) parallel electronic structure code using a wavelet basis set. Wavelets form a real space basis set distributed on an adaptive mesh. Surfaces and isolated systems can be simulated with the proper boundary conditions and GTH or HGH pseudopotentials are used to remove the core electrons.
