Folding@home is a distributed computing project — people from throughout the world download and run software to band together to make one of the largest supercomputers in the world. Every computer takes the project closer to our goals. Folding@home uses novel computational methods coupled to distributed computing, to simulate problems millions of times more challenging than previously achieved.
What is Folding@home? What is protein folding?
Folding@home is a distributed computing project, that very simply stated, studies protein folding and misfolding. Protein folding is explained in more detail in the scientific background section.
That wasn’t enough for you? Read Wikipedia’s:
Folding@Home (also known as FAH or F@H) is a distributed computing (DC) project designed to perform computationally intensive simulations of protein folding and other molecular dynamics (MD). It was launched on October 1, 2000, and is currently managed by the Pande Group, within Stanford University’s chemistry department, under the supervision of Professor Vijay Pande. Folding@home is the most powerful distributed computing cluster in the world, according to Guinness, and one of the world’s largest distributed computing projects. The goal of the project is “to understand protein folding, misfolding, and related diseases.”
Accurate simulations of protein folding and misfolding enable the scientific community to better understand the development of many diseases, including sickle-cell disease (drepanocytosis), Alzheimer’s disease, BSE (mad cow disease), cancer, Huntington’s disease, cystic fibrosis and other aggregation-related diseases.  More fundamentally, understanding the process of protein folding — how biological molecules assemble themselves into a functional state — is one of the outstanding problems of molecular biology. So far, the Folding@home project has successfully simulated folding in the 5-10 microsecond range — a time scale thousands of times longer than it was previously thought possible to model. The Pande Group goal is to refine and improve the MD and Folding@home DC methods to the level where it will become an essential tool for the MD research.  For that goal they collaborate with various scientific institutions.  As of December 13, 2007, fifty-four scientific research papers have been published using the project’s work. A University of Illinois at Urbana-Champaign report dated October 22, 2002 states that Folding@home distributed simulations of protein folding are demonstrably accurate.
On September 16, 2007, the Folding@Home project officially attained a performance level higher than one petaFLOPS, becoming the first computing system of any kind to do so (!), although it had briefly peaked above one petaFLOPS in March 2007.. In comparison, the fastest supercomputer in the world (as of November 2007, IBM’s Blue Gene/L supercomputer) peaks at 478.2 teraFLOPS (1000 teraFLOPS=1 petaFLOP). The Folding@home supercomputer currently operates at 1048 teraFLOPs, 772 teraFLOPS comes from the PlayStation 3. (Wow! So finally those gaming consoles are not good for nothing but playing 😛 😀 )
Please download the software & join my team – Bahrain Team – #110997 to contribute for a better world 🙂 I have dedicated the free time of my PS3 – and soon my ALIENA – for such project, and opened a blog for that: http://fah-bh.blogspot.com
Cheers, and peace to the world 🙂
