FoldingAtHome (also known as FAH, Folding@home, or F@h) is a computer project that supposes the distributed network of computers that give their computing power to science needs. In particular, FoldingAtHome uses those capacities to model protein folding and protein movements. This project uses the simulation method of modeling, which is unusual for scientific research.

The FAH computing network is considered as one of the fastest on Earth. Its computing power fluctuates about 2.4 exaflops, peaking at 2.43 exaflops in April 2020 – at the first peak of coronavirus pandemic. Throughout the whole activity of FAH, scientists completed 225 paper research projects. Such high computing power allows the scientists to perform the atomic-level simulations of protein folding thousands of times longer than ones performed earlier.

Understanding the numbers
The most powerful quantum computers (30-qubits) are able to perform at only 10 teraflops (10 trillion floating-point operations per second). 2.4 exaflops equals 2.4 quadrillion (2400 trillion) floating point operations per second. Surely, in the near future we will see much more powerful quantum computers, but networks like FAH are currently cheaper and more flexible than the network of quantum computers with the same computing power.
