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.

September 11 and Religion

The Los Angeles Times has reported Obama's speech for 9-11, where he claims that it was the perversion of religion, rather religion itself that was the cause of terrorism.

Religious Loyalty

A surprise study published in The Journal for the Scientific Study of Religion and reported by Scientific American suggests that the so-called Generation X group are more loyal to their religious background than the "Baby Boomers". By the same token the survey of some 37,000 Americans also noted that the number with no religious affiliation doubled in the 1990s and continues to increase.
