What is it?It is a new distributed supercomputing infrastructure made of many individual PlayStation3 and NVIDIA graphics cards joined together to deliver high-performance full-atom biomolecular simulations. This project gives a new powerful computational tool to scientists and you are an important part of it. If you enjoy science, you can participate by donating the computing time of your PlayStation3 or your NVIDIA graphics card to scientific research by running molecular simulations while not playing. Simply follow the instructions below to join, get your credits for the results you return, join a team, meet and exchange experience with other paritcipants with the forums. Join with your Playstation3
Join with your Nvidia graphics card (beta)
Problems? People at the project forum will help you. Why should you join?The computational power of graphics hardware is much higher than standard processor due to the large amount of calculations which are required to display realistic three-dimensional images. This is achieved by a design and programming style change (see CUDA). A conventional processor dedicates a relatively large fraction of its transistors to complex control logic, to maximise performance of a serial code. The Cell processor contains 8 fast Synergetic Processing Elements (SPEs) designed to maximise arithmetic throughput. Graphical processing units (GPUs) devices have a very large number of slower cores maximizing parallel throughput. For example, just ten thousand volunteers provides the computational power of the largest supercomputer on the planet for certain specific applications.

We are located in the Computational Biochemistry and Biophysics Laboratory , Research Unit on Biomedical Informatics (GRIB) at University of Pompeu Fabra, within the Barcelona Biomedical Research Park (PRBB). Molecular simulations of Triose Phospate Isomerase (TPI) enzymesThis workunit investigates the conformational differences that arise when TPI enzymes undergo tyrosine nitration as a consequence of inflammation, defective mithocondrial respiration and oxydative stress. Workunits last around one day and must completed before 4 days. 
FORWARD-REVERSE STEERED MOLECULAR DYNAMICSPotassium ion permeation in Gramicidin A We are giving workunits comprising full-atom simulations of gramidicin A for ion transport, a total of 30,000 atoms. Each workunit lasts less than one day and you have to complete it before 4 days. Movie.
