Remember hearing about SETI@home? Check out, and download, Gridrepublic.org:

GridRepublic members run a screensaver that allows their computers to work on public-interest research projects when the machines are not otherwise in use. This screensaver does not affect performance of the host computer any more than an ordinary screensaver does.

By aggregating idle resources from users around the world, we create a massive supercomputer.

Gridrepublic is built on the system that started as SETI@home, which was turned into a general distributed computing platform BOINC. Gridrepublic is a central place for all projects using this distributed platform, where you can dowload & install the system and even better, choose which projects your computer’s idle time will be supporting, including:

Einstein@home: you can contribute your computer’s idle time to a search for spinning neutron stars (also called pulsars) using data from the LIGO and GEO gravitational wave detectors.

BBC Climate Change: The same model that the Met Office uses to make daily weather forecasts has been adapted to run on home PCs. The model incorporates many variable parameters, allowing thousands of sets of conditions. Your computer will run one individual set of conditions– in effect your individual version of how the world’s climate works– and then report back to the research team what it calculates. This experiment was described on the BBC television documentary Meltdown (BBC-4, February 20th, 2006). Note: workunits require several months of screensaver time; faster computers recommended.

Rosetta@home: needs your help to determine the 3-dimensional shape of proteins as part of research that may ultimately contribute to cures for major human diseases such as AIDS / HIV, Malaria, Cancer, and Alzheimer’s.
Proteins@Home: investigating the “Inverse Protein Folding Problem”: Whereas “Protein Folding” seeks to determine a protein’s shape from its amino acid sequence, “Inverse Protein Folding” begins with a protein of known shape and seeks to “work backwards” to determine the amino acid sequence from which it is generated.

Quantum Monte Carlo: Reactions between molecules are important for virtually all parts of our lives. The structure and reactivity of molecules can be predicted by Quantum Chemistry, but the solution of the vastly complex equations of Quantum Theory often require huge amounts of computing power. This project seeks to raise the necessary computing time in order to further develop the very promising Quantum Monte Carlo (QMC) method for general use in Quantum Chemistry.
