Folding@home is a volunteer computing project for disease research that simulates protein folding and other types of molecular dynamics.
Instead of using the computing power of a single computer, the project divides a complex task into subtasks, distributes them among multiple computers, and uses their computing power to accomplish the task.
Through distributed computing, the project utilizes the unused processing resources of personal computers and servers on which the software is installed, thus contributing to disease research.
