Dr. Ramos-Horta provided the following comments on his work.
Lev works for the Victorian Partnership for Advanced Computing as a systems administrator for Linux clusters. As per that organisation, this site is dedicated to issues concerning High Performance Computing, Scientific Computing and Supercomputing, along with advanced collaborative technologies such as the Access Grid through the Australian Research Collaboration Service.
The crocodile logo was designed by Victoria Jankowski. It was first used on the cover of Neon-komputadór, the first IT training manual for the Ministry of Foreign Affairs in East Timor which was printed and translated by the United Nations Development Programme. The crocodile represents the Timorese people and is the emblem of their land. The integrated circuit represents their independent connectivity to the wider world.
That's enough of me talking about myself in the third person like Cerebus The Aardvark. For the rest of this site it will be in first person. After all, I wrote this content.

Installing NAMD 2.7b1 with CUDA on a 64-bit AMD Opteron Cluster running CentOS 5 Linux
Submitted by lev_lafayette on Wed, 05/13/2009 - 02:12.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.
