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.

1. What is this?
A proposal to use the free and open source technologies used by Livejournal (livejournal.com) and further developed by Dreamwidth (dreamwidth.org) to create an effective social collaboration and journaling site for Australian researchers.

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."

Purpose of the Document
The Access Grid is a software suite that provides video, audio and file collaboration, built on well-known streaming audio (Robust Audio Tool, or RAT) and Vic (Video Conferencing tool). This document seeks to help network administrators implement Access Grid with respect to local security policies and firewalls.
First, collect the necessary modules:
module load pgi/7.2, Download and extract (
tar xvf openmpi-1.3.2.tar.gz) openmpi in the appropriate place (
What do you do when you receive a "bad superblock" error on a USB or other Flash drive? Well, firstly you kick yourself for not backing up important data on said drive for the past nine days; you're old enough to know better than that. Secondly, you kick yourself for using that piece of rubbish called the FAT32 filesystem which was default for Windows 95, but is what every USB drive ships with because it's the last file format released by Microsoft that actually communicates with other operating systems, despite the fact that it's as buggy as hell and is prone to disaster.

VAMP/VASP [Vienna Ab-initio Simulation Package] is a package for performing ab-initio quantum-mechanical molecular dynamics (MD) using pseudopotentials and a plane wave basis set. The approach implemented in VAMP/VASP is based on a finite-temperature local-density approximation (with the free energy as variational quantity) and an exact evaluation of the instantaneous electronic ground state at each MD-step using efficient matrix diagonalization schemes and an efficient Pulay mixing. These techniques avoid all problems occurring in the original Car-Parrinello method which is based on the simultaneous integration of electronic and ionic equations of motion. The interaction between ions and electrons is described using ultrasoft Vanderbilt pseudopotentials (US-PP) or the projector augmented wave method (PAW). Both techniques allow a considerable reduction of the necessary number of plane-waves per atom for transition metals and first row elements. Forces and stress can be easily calculated with VAMP/VASP and used to relax atoms into their instantaneous groundstate.

Body Language and Conversation
Conservative dressing in Indonesia consists of a collared shirt for men and long pants. Women are expected also to wear pants or skirts that go beyond the knee and tops which cover the shoulder. Shorts and t-shirts are accepted in tourist areas and bikinis on tourits beaches, but otherwise they are best avoided, and certainly must be avoided when visiting an Indonesian home or place of worship. Sarongs, short-pants and t-shirts are normally worn around the home. In Balinese Hindu temples, a sash should be worn around the waist.
Prepositions establish relationships between words and are therefore useful in building phrases. Some common examples in Bahasa Indonesia include the following:
At, In, On (all referring to place), use "Di".
At, In, On, For (all referring to time, use "Pada jam", "Dalam", "Pada", "Selama", respectively.
For (a purpose) use "Untuk"
From use "Dari"
Towards use "Ke"
Inside, Outside use "Di dalam", "Di luar", respectively
Since and Until use "Sejak", "Sampai", respectively
About and With use "Tentang" and "Dengan", respectively
