Join PS3GRID

PS3GRID is a volunteer computing project on the PlayStation3 for full-atom molecular simulations of proteins.Your contribution is very important because our CellMD software runs over an order of magnitude faster on the PlayStation3 opening the way to innovative scientific experiments.

About PS3GRID.net

What is PS3GRID.NET?

The ps3grid.net project gives a new powerful tool to computational scientists and you are an important part of it. PS3GRID opens novel computational scenarios by using BOINC and the first full-atom molecular dynamics code (CellMD) specially optimized to run on the Cell processor and the PlayStation3. New biomedical applications suddenly become possible giving a new role to computational biology for biomedical research.

If you like science, you can participate with your PlayStation3 to scientific research by running molecular simulations while not playing. We will use it at its best by running only the most optimized software: With Cell MD, the Cell processor is equivalent to almost 20 PCs (16 times faster on the 6 SPEs of the PS3).

For example, if 1,000 people join this cooperative effort we will be able to utilize the computational equivalent of 16,000 single-core computers.

Why not install Linux? With Linux the PS3 can double as a normal computer for browsing the net, writing documents and running BOINC.

For more information or if you need to contact us write to Gianni De Fabritiis (ps3grid@gmail.com). Also, visit our virtual lab MultiscaleLab.
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).

Science: Molecular experiments

Molecular simulations of Triose Phospate Isomerase (TPI) enzymes

This 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 DYNAMICS

Potassium 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.

May 9, 2008 Detail of the first numerical experiment.
The first set of numerical experiments run on ps3grid.net produced 5,000 trajectories, 4 microseconds of simulated time, over 200 years of CPU time with a daily output of 100 ns and few GBytes, two orders of magnitude closer to single-molecule pulling experiments. Thanks to all volunteers for this effort.

April 10, 2008 Forums update.
PS3GRID forums have been slightly reorganized to improve the usability.

March 31, 2008 Server is up.
Server is up again after PRBB server room maintainance.

March 28, 2008 Master URL change for www.ps3grid.net.
The master url of the project has changed to the simpler http://www.ps3grid.net. Previous master url will still work, although the boinc client will notify that you should use the new one.

March 27, 2008 Server downtime tomorrow March 28.
Tomorrow Friday, there will be a general shutdown in the PRBB server room which will affect ps3grid.net. The server will remain down for approximatevely 4 hours. Everything should get back to normal after the server is booted again.
