Folding At Home Client Download !FREE!

FAHClient can be run in the command-line; this means that is possible to run Folding@home without Web Control or Advanced Control. FAHClient has an API for third-party applications and can be controlled via Telnet. For documentation on all of these things, see the V7 Advanced page.

There are several important changes in V8. First, there are now only two parts to the client software, the backend (fah-client-bastet) which runs behind the scenes handling most of the logic of running Folding@home and the frontend (fah-web-client-bastet) Web Control which provides the user interface. The v8 backend is equivalent to FAHClient in v7. The v8 Web Control combines the features of the v7 Web Control, FAHControl and FAHViewer.

Second, the concept of folding slots in v7 does not exist in v8. Instead of configuring slots you only have to tell Folding@home which compute resources (e.g. CPUs and GPUs) you would like it to use. It will then automatically allocate those resources in the most efficient way. This change both simplifies the setup of Folding@home and makes it possible for Folding@home to allocate multiple CPUs and GPUs to the same Work Unit. By allocating more resources to a single WU Folding@home can decrease simulation times and achieve scientific results more quickly.

The v8 client is still in beta testing. We have been testing it for several months so it is in pretty good shape but there may still be some bugs and missing features. Beta releases can be found on the beta software page. You can still download stable v7 releases on the main software download page.

The v8 client can run on Windows, macOS, Linux and ARM Linux. The install procedure for v8 is essentially the same as for the v7 client with the exception that on Linux you now only need to install the fah-client package. V8 specific install instructions will be written in the near future. For now, please refer to the v7 install guides.

The v8 Folding@home software is controlled via a web browser using Web Control. Web Control can be reached by navigating to From this page your browser will attempt to connect to client software running on the same computer the browser is running on.

The client home page is the first screen you will encounter. After connecting, it will display the status of your F@H client. If you have not yet configured a username, team or passkey a dialog will popup asking you to do so via the Settings page or choose to fold anonymously.

The Settings page allows you to configure the Folding@home software on your machine. For your changes to take effect, you must click the button in the top right. Or click to discard unwanted changes.

In the User Settings section you can set your Username, Team and Passkey. These settings affect how you receive Folding@home points. More information about these settings and the points system can be found in the FAQ.

Check Fold When Idle if you only want Folding@home to operate when your computer is not in use. In practice, this means that while you are moving the mouse or typing, Folding@home will not run. If your computer is setup to go to sleep when idle then Folding@home will not run at all. To use Fold When Idle effectively you may need to configure your computer to only enter sleep mode when running on battery.

In the GPUs section you will find a list of the supported Graphics Processing Units available on your machine. GPU folding is the most efficient and usually earns much higher points. In some cases, folding on the GPU can slow your machine down too much. You can always disable GPU folding here. More information about GPU folding can be found in the FAQ.

In the Peers section you can add the IP addresses or hostnames of other Folding@home clients on your network. You can then control and monitor these remote clients from Web Control much like you could with FAHControl with the v7 software. However, you must configure the remote clients to allow remote access and doing so has security implications. Details on how to do so will be added later.

The Log Viewer allows you to view detailed technical information about the folding simulations running on your machine. Making sense of these logs requires expert knowledge of the Folding@home software. If you encounter a problem with F@H you may be asked to share the contents of this log file.

I have been trying to connect to Folding@Home today and just get a spinning wheel. Multiple restarts and no dice. Seems as if I cannot connect to a folding@home server. Any ideas on how to fix this?

Folding@home (FAH or F@h) is a distributed computing project aimed to help scientists develop new therapeutics for a variety of diseases by the means of simulating protein dynamics. This includes the process of protein folding and the movements of proteins, and is reliant on simulations run on volunteers' personal computers.[5] Folding@home is currently based at the University of Pennsylvania and led by Greg Bowman, a former student of Vijay Pande.[6]

Folding@home is one of the world's fastest computing systems. With heightened interest in the project as a result of the COVID-19 pandemic,[8] the system achieved a speed of approximately 1.22 exaflops by late March 2020 and reached 2.43 exaflops by April 12, 2020,[9] making it the world's first exaflop computing system. This level of performance from its large-scale computing network has allowed researchers to run computationally costly atomic-level simulations of protein folding thousands of times longer than formerly achieved. Since its launch on October 1, 2000, Folding@home was involved in the production of 226 scientific research papers.[10] Results from the project's simulations agree well with experiments.[11][12][13]

Proteins are an essential component to many biological functions and participate in virtually all processes within biological cells. They often act as enzymes, performing biochemical reactions including cell signaling, molecular transportation, and cellular regulation. As structural elements, some proteins act as a type of skeleton for cells, and as antibodies, while other proteins participate in the immune system. Before a protein can take on these roles, it must fold into a functional three-dimensional structure, a process that often occurs spontaneously and is dependent on interactions within its amino acid sequence and interactions of the amino acids with their surroundings. Protein folding is driven by the search to find the most energetically favorable conformation of the protein, i.e., its native state. Thus, understanding protein folding is critical to understanding what a protein does and how it works, and is considered a holy grail of computational biology.[14][15] Despite folding occurring within a crowded cellular environment, it typically proceeds smoothly. However, due to a protein's chemical properties or other factors, proteins may misfold, that is, fold down the wrong pathway and end up misshapen. Unless cellular mechanisms can destroy or refold misfolded proteins, they can subsequently aggregate and cause a variety of debilitating diseases.[16] Laboratory experiments studying these processes can be limited in scope and atomic detail, leading scientists to use physics-based computing models that, when complementing experiments, seek to provide a more complete picture of protein folding, misfolding, and aggregation.[17][18]

Due to the complexity of proteins' conformation or configuration space (the set of possible shapes a protein can take), and limits in computing power, all-atom molecular dynamics simulations have been severely limited in the timescales that they can study. While most proteins typically fold in the order of milliseconds,[17][19] before 2010, simulations could only reach nanosecond to microsecond timescales.[11] General-purpose supercomputers have been used to simulate protein folding, but such systems are intrinsically costly and typically shared among many research groups. Further, because the computations in kinetic models occur serially, strong scaling of traditional molecular simulations to these architectures is exceptionally difficult.[20][21] Moreover, as protein folding is a stochastic process (i.e., random) and can statistically vary over time, it is challenging computationally to use long simulations for comprehensive views of the folding process.[22][23]

Protein folding does not occur in one step.[16] Instead, proteins spend most of their folding time, nearly 96% in some cases,[24] waiting in various intermediate conformational states, each a local thermodynamic free energy minimum in the protein's energy landscape. Through a process known as adaptive sampling, these conformations are used by Folding@home as starting points for a set of simulation trajectories. As the simulations discover more conformations, the trajectories are restarted from them, and a Markov state model (MSM) is gradually created from this cyclic process. MSMs are discrete-time master equation models which describe a biomolecule's conformational and energy landscape as a set of distinct structures and the short transitions between them. The adaptive sampling Markov state model method significantly increases the efficiency of simulation as it avoids computation inside the local energy minimum itself, and is amenable to distributed computing (including on GPUGRID) as it allows for the statistical aggregation of short, independent simulation trajectories.[25] The amount of time it takes to construct a Markov state model is inversely proportional to the number of parallel simulations run, i.e., the number of processors available. In other words, it achieves linear parallelization, leading to an approximately four orders of magnitude reduction in overall serial calculation time. A completed MSM may contain tens of thousands of sample states from the protein's phase space (all the conformations a protein can take on) and the transitions between them. The model illustrates folding events and pathways (i.e., routes) and researchers can later use kinetic clustering to view a coarse-grained representation of the otherwise highly detailed model. They can use these MSMs to reveal how proteins misfold and to quantitatively compare simulations with experiments.[7][22][26] ff782bc1db
