# BOINC

**BOINC** (**Berkeley Open Infrastructure for Network Computing**) is middleware that enables users all over the world to help solve important scientific and mathematical problems. Launched on April 10, 2002, it was developed at the Space Sciences Laboratory at UC Berkeley, which in 1999 launched the [email protected] project. BOINC was created to build upon the success of [email protected], and expand the platform model to other scientific problems that require massive computing power.

## How does BOINC work?

Users install the BOINC software on their computer or mobile device, and contribute their spare CPU and GPU resources to a specific computing project. The resources are only used if the machine is idle, and, in the case of a mobile device, plugged-in with the battery charged to at least 90%.

BOINC is a form of distributed computing, although it is more accurately referred to as **volunteer computing** or **grid computing**. Comprising over 310,000 participants and 800,000 devices, if the BOINC system were a single computer, it would be the fourth most powerful supercomputer in the world.

## Scientific fields

Each scientific problem computed by BOINC has its own dedicated project middleware. Fields of science with one or more dedicated projects include:

- Mathematics
- Linguistics
- Medicine
- Molecular biology
- Climatology
- Environmental science
- Astrophysics
- Physics
- Evolution
- Computer Science

## Supported devices

Depending on the project, the supported operating systems, architectures, and devices may include one or more of the following:

- Microsoft Windows
- macOS
- iOS
- Android
- Linux (Intel or ARM architectures)
- BSD
- GPUs: NVIDIA, Radeon, or Intel
- VirtualBox VMs (virtual machines)

As of this writing, all BOINC projects support Microsoft Windows and Linux on Intel.
