EnglishHow Does Folding@home Work on My Computer?
Updated
Folding@home turns your computer's idle power into part of a global supercomputer for biomedical research. You download a small client, install it, and let it run in the background; your machine receives a piece of a real research simulation, computes it, and sends the result back. It works on Windows, macOS, and Linux, and you don't need an account to start. The project is free and open source, and it has been running since October 2000.
The three-step process
The site describes the workflow in three steps:
- Download — pick your platform (Windows, macOS, or Linux) and get the installer.
- Install — run the installer. No account is required to start, and the client is open source.
- Fold — your computer downloads a small piece of a real research simulation, runs it in the background, and returns the result. You earn points, and the cycle repeats.
The whole setup is described as taking about a minute.
What your computer is actually doing
Your machine isn't running a generic benchmark. It receives a work unit — a slice of a molecular simulation tied to a specific disease study — computes how proteins fold or move, and returns that result to the researchers. This is distributed computing: instead of one lab owning a supercomputer, thousands of volunteers' machines each handle a small piece.
The research areas the site highlights include:
| Disease area | What the project says it found |
|---|---|
| Cancer | Work on BRCA1 revealed new therapeutic strategies to combat breast cancer |
| COVID-19 | Hit 2.43 exaflops and helped identify a potential new antiviral in animal testing |
| Alzheimer's | Work on ApoE is uncovering the mechanism of the most common cause of dementia |
| Ebola | Identified transient "cryptic pockets" in the virus protein that other methods missed |
The project reports 2.43 exaflops as the world's first exaflop computing system (April 2020), more than 500 peer-reviewed papers since launch, and 25+ years of operation. It's led by Dr. Greg Bowman and the Folding@home Consortium, a network of academic labs.
Points, teams, and leaderboards
Contributing earns you points. If you want more than a solo setup, you can join a team or start one and climb the leaderboard. The project has supported competitive teams since 2000, with full stats, project transparency, and an open client. There's also a Discord, forum, and GitHub for power users who want to bring a GPU or dig into the details.
What you need to know before starting
- Platforms: Windows, macOS, Linux.
- Account: not required to start.
- Cost: the site states it's free.
- Source: open source client.
- Background operation: it runs while you use your computer normally.
If you want to contribute compute to biomedical research with minimal setup, this is a low-friction way to do it. If you'd rather not have a background process using your machine's resources, that's the main trade-off to weigh before installing.
