1 - Getting Help With Folding@Home

Some of you may have found this Forum because you encountered an issue when attempting to run the F@H Client, while others want to learn more about the F@H Project. Either way, there are a number of resources allowing for self-helping and self-learning which you can avail:

You can start by searching this Forum to see if someone else has already reported the same problem. If so, you can try the suggested solutions (if applicable).
You could try reading the FAQs to see if your question is answered.

We're happy to help you with any kind of F@H related problems. Most of the time we'll need information from you to help diagnose your problem. The log is a very vital source of information when it comes to troubleshooting the F@H Clients. The first ~100 lines of the log shows essential information about your system and any settings that the F@H Client has been configured for. Secondly, you should also include portions of the log which shows error messages especially the first time it happens. Do note that the forum has a limit of 60,000 characters (including spaces) so you can trim off the progress reported from 2& to 99%. For more details, please see How To Post A Log File (details below).

For the registered Forum Members, please note that our General Policies can be found here.

2 - Temporary Restrictions For New Members

Please note that if you have recently joined this Forum, you may not be able to use some of the Forums' features initially. Our anti-spam policy sets a threshold just high enough that a spam-bot is unlikely to reach, while the Donors can, provided they are around long enough. Some of the features that you initially can't use are:

Can't post URLs
Can't quote another user

By participating normally, these temporary restrictions will be automatically removed

3 - Introduction To Common F@H Jargon

While browsing this Forum, you may come across some unusual acronyms which are commonly used by F@H Donors. Below is a list of commonly used acronyms and jargons:

WU - Work Unit is a small time-slice of protein processing that is downloaded by your F@H Client from the appropriate Server. Your system will process it and once it finishes folding, will upload the result to the Server and will request another WU unless the F@H Client is set to Finish.
Note: The duration to process this WU will vary from few hours to few days depending on the type of WU, F@H Client, system usage and several other factors. You will receive credits for a WU once it is successfully uploaded to the Servers and the Official Stats are updated (happens every hour).

PRCG - Project Run Clone Gen, is used to identify a WU that is assigned to you.
Project: Biological system.
Run: Different starting configuration (positions) of atoms.
Clone: Different starting velocities of atoms (each Run can have multiple Clones with different starting velocities).
Gen: Time sequence (so Clone 1, Gen 2 is sent after Clone 1, Gen 1 is received and processed).
Note: For a given Project number (and Protein name) there are many Runs, Clones and Gens so don't be alarmed if you seem to be processing the same Project/Protein again. The F@H Project doesn't assign duplicate WUs on purpose to keep Donors folding.

PPD - Points Per Day is the total number of points your system is generating while folding the assigned WU(s).
Note: PPD will vary from WU to WU (even if they belong to the same Project) and will be effected by system usage and other factors.

TPF - Time Per Frame means how long it takes to finish 1% of the assigned WU as 1% of a WU is equal to one frame.
Note: The TPF can vary significantly if the system is being used. A dedicated folding system experiences less fluctuations.

FahCore_XX - The piece of software that folds the assigned WU.

FahClient - The piece of software that manages FahCore_XX.

FAHControl (Advanced Control) - The Graphical User Interface (GUI) for FahClient.

FAHViewer - A protein viewer that either shows the current protein being folded by the FahCore_XX or a demo one if FahCore_XX doesn't generate the data.

FAHSlot (Slot) - How the FahClient manages your system's resources to fold the assigned WU. It is either a Central Processing Unit (CPU) or a Graphical Processing Unit (GPU) Slot.

4 - Getting Started With F@H (Basic)

If you would like to participate in the F@H Project, you can install the F@H Client on a compatible system. If you don't own the system, ensure you have the system owner's permission (usually written) as per the EULA. Below is a quick overview to help you get started. Please note that folding is very stressful on the system which means that it may generate extra heat, noise and consume more power. For a properly configured system, it isn't an issue. For systems that are overclocked, it may cause issues. The official stance of F@H is that it doesn't not support or encourage overclocking. The integrity for science supersedes any overclocking record.

Supported System Configuration
The following Operating Systems (OS) and hardware configurations are supported by F@H Software for folding. Please note that the older the hardware is, the longer it needs to fold per day to ensure that it can finish the assigned WU successfully before the Timeout date:
Windows (32 bit) - Windows 10, Windows 8, Windows 7

CPU with SSE2 or AVX2 or better - Intel Core 2 Duo or newer, Athlon 64 or newer
GPU with OpenCL 1.2 with Double Precision - AMD Radeon HD 5830 or newer, Nvidia GeForce GT 710 or newer

Windows (64 bit) - Windows 10, Windows 8, Windows 7

CPU with SSE2 or AVX2 or better - Intel Core 2 Duo or newer, Athlon 64 or newer
GPU with OpenCL 1.2 with Double Precision - AMD Radeon HD 5830 or newer, Nvidia GeForce GT 710 or newer

Linux (64-bit) - Centos, Debian, Fedora, Mint, Redhat, Ubuntu

CPU with SSE2 or AVX2 or better - Intel Core 2 Duo or newer, Athlon 64 or newer
GPU with OpenCL 1.2 with Double Precision - AMD Radeon HD 5830 or newer, Nvidia GeForce GT 710 or newer

macOS (64-bit) - Catalina, Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion, Lion

CPU with SSE2 or AVX2 or better - Intel Core 2 Duo or newer, Athlon 64 or newer

Start Folding
After successfully installing the F@H Client, it will download a WU which has a Timeout date and an Expiration date. Your system can contribute by folding as as long as you can return the assigned WU before the Timeout date. Credit is granted for successfully completed WUs based upon how long it took to fold the WU. The time taken to fold the WU starts from when the WU was assigned to the F@H Client until it was successfully completed and uploaded to the F@H Servers.

Credit For WUs
All WUs get bonus points if they are returned before the Timeout date as long as you qualify for it. It uses the scheme of Quick Return Bonus (QRB) to incentivize folding WUs quickly since more science is being done. Credit for successfully completed WUs will not appear in the official stats pages until at least an hour or more after the results are uploaded. Below is a quick summary of how the credits system work:

Before Timeout date - You will get bonus credit once you have folded the WU (bonus varies from system to system and increases for faster completion)
Exceed Timeout date - WU will be reissued to another system while yours is currently folding it. You will get base credit once you have folded the WU (it is significantly less when compared to bonus credits)
Exceed Expiration date - WU is deleted from your system. You won't get any credit (increase the hours for folding or update/retire the system)

In order for Donors to take advantage of QRB, there are some basic requirements which they must meet:

Use F@H Software (Download)
Configure the F@H Client with a Passkey (Details)
Successfully fold 10 WUs before their timeout date by using the same combination of Username and Passkey
Maintain a successful return rate of >= 80% for WUs, i.e. out of every 10 WUs assigned, you must successfully return at least 8 completed WUs (Check)

5 - Getting Started With F@H (Advanced)

For this section, we shall assume that you're familiar with the F@H Software and can easily navigate your way around the F@H Community. There are aspects of the F@H Software that can be tweaked to increase the folding performance of your system and/or allow you to manage multiple systems easily.

Tweaking Slot Options
The default settings ought to be fine for most Donors. However, if you would like to tweak some settings specific to the FAH Slot, you can still do so. Below is the procedure to change the slot settings:

Open up Advanced Control (AKA FAHControl)
Click on Configure
Select the Slots Tab
Select the slot you would like to configure with a single click
Click the Edit button
Scroll down the Folding Slot window to the Extra slot options (expert only) section
Click on the Add button
A Edit Options box will appear where you have to enter the correct values for Name and Value (details below)
Click OK button to close the Edit Options box
Click OK button to close the Folding Slot window
Click on the Save button to save the changes made to the slot

A list of common options are:

Code: Select all

Name					    Value		Description
----------------------------------------------------------------------------------------------------------------------------------------------------------
client-type				advanced	Assigns WUs in late-stage beta if available
next-unit-percentage	X			 X should be between 90 and 100. It tells when the next WU should be downloaded after the current WU reaches X percentage
max-units		        X		    X can be any number; 0 is indefinite. It tells when to pause the slot after X WUs are completed
checkpoint	     	  X		    X is a value between 3 and 30. It will create a checkpoint after X minutes (not all FahCore's accept this parameter)
pause-on-start	      true	    FAHClient starts the slot in the pause state
pause-on-start	      false	   FAHClient will start the slot normally

Managing Multiple FAHClients
If you have multiple systems folding within the same network, they can be easily monitored by a single system. Below are the steps to do so.

Remote System

Open up Advanced Control (AKA FAHControl)
Click Configure
Click Remote Access tab
Enter Password
Enter either the Monitor System's IP or the IP Address range in the Allow field
Click Save
Restart the system

Monitor System

Open up Advanced Control (AKA FAHControl)
Click Add
Under Name, enter the Remote System's name or any other name
Under the Address, enter either the Hostname or IP address of the Remote System
Under the Password, enter the password used in the Remote System
Click Save

6 - How To Post A Log File (Windows)

There are few methods to locate the log file for the F@H Client that you can use to locate, copy and paste your log to this Forum. However, please note that:

We generally don't need the progress messages between 2% and 99% so they can be removed
A single post has a limit of 60,000 characters so if you encounter this limit, you can remove repetitive messages or split your log file across multiple posts
The default setting of verbosity (3) should be used, any higher will print additional data that is unnecessary which makes it very difficult to troubleshoot in the majority of cases

Method 1 (Windows 10, Windows 8, Windows 7)

Ensure that FAHClient is running by looking for the F@H icon in the notification area of the task bar
Right click the F@H icon
Select Advanced Control (AKA FAHControl) from the menu options
Once Advanced Control opens, select the Log tab
Untick Follow
Click the Refresh button
Click the Copy button
Go to the Full Editor in this Forum by clicking on; New Topic or Post Reply or Full Editor
Click the Code button
Within the code tags, paste the log
Click the Submit button to post your post. If you reach the 60,000 character limit, remove progress messages between 2% and 99% and/or split your log across multiple posts

Method 2 (Windows 10, Windows 8, Windows 7)

Type %AppData%\FAHClient in Windows Explorer and hit Enter (If that doesn't work, try %ALLUSERSPROFILE%\FAHClient)
A window will open which will contain F@H files and folders. Depending on your need, focus on:
A) log file -> This is the most recent log file
B) logs folder -> This contains the previous 16 log files
Double click on the appropriate log file to open it
Copy the contents of it
Go to the Full Editor in this Forum by clicking on; New Topic or Post Reply or Full Editor
Click the Code button
Within the code tags, paste the log
Click the Submit button to post your post. If you reach the 60,000 character limit, remove progress messages between 2% and 99% and/or split your log across multiple posts

Method 3 (Windows 8, Windows 7)

Click the Start Button
Click on All Programs
Click on FAHClient folder
Click on Data Directory folder
A window will open which will contain F@H files and folders. Depending on your need, focus on:
A) log file -> This is the most recent log file
B) logs folder -> This contains the previous 16 log files
Double click on the appropriate log file to open it
Copy the contents of it
Go to the Full Editor in this Forum by clicking on; New Topic or Post Reply or Full Editor
Click the Code button
Within the code tags, paste the log
Click the Submit button to post your post. If you reach the 60,000 character limit, remove progress messages between 2% and 99% and/or split your log across multiple posts

7 - How To Post A Log File (Linux)

There are few methods to locate the log file for the F@H Client that you can use to locate, copy and paste your log to this Forum. However, please note that:

We generally don't need the progress messages between 2% and 99% so they can be removed
A single post has a limit of 60,000 characters so if you encounter this limit, you can remove repetitive messages or split your log file across multiple posts
The default setting of verbosity (3) should be used, any higher will print additional data that is unnecessary which makes it very difficult to troubleshoot in the majority of cases

Method 1 (Centos, Debian, Fedora, Mint, Redhat, Ubuntu)

Open up up Advanced Control (AKA FAHControl)
Select the Log tab
Untick Follow
Click the Refresh button
Click the Copy button
Go to the Full Editor in this Forum by clicking on; New Topic or Post Reply or Full Editor
Click the Code button
Within the code tags, paste the log
Click the Submit button to post your post. If you reach the 60,000 character limit, remove progress messages between 2% and 99% and/or split your log across multiple posts

Method 2 (*unix)

Navigate to /var/lib/fahclient
You will see F@H files and folders. Depending on your need, focus on:
A) log file -> This is the most recent log file
B) logs folder -> This contains the previous 16 log files
Double click on the appropriate log file to open it
Copy the contents of it
Go to the Full Editor in this Forum by clicking on; New Topic or Post Reply or Full Editor
Click the Code button
Within the code tags, paste the log
Click the Submit button to post your post If you reach the 60,000 character limit, remove progress messages between 2% and 99% and/or split your log across multiple posts

A sample log file covering the needed sections; System Info and Configuration along with normal folding process is shown below:

9 - Generic Troubleshooting Tips

Below are some broad suggestions to help fix an issue that you might have. Please note that these are generic tips and suggestions so it may not apply to your particular setup. We do encourage you to create a thread in the appropriate Forum to get help specific to your needs.

Overheating CPU

Make sure that the cooling system is properly set-up
Make sure that the cooling system is clean and that no dust or debris is blocking the ventilation
Reduce the number the CPUs used by F@H. In V7, this is done via the Advanced Control -> Configure -> Slots Tab -> CPU -> Replace -1 with a number greater than or equal to 1
If you CPU is overclocked, consider reducing the frequencies to lower the heat output

Overheating GPU

Make sure that the cooling system is properly set-up
Make sure that the cooling system is clean and that no dust or debris is blocking the ventilation
If you GPU is overclocked, consider reducing the frequencies to lower the heat output

Missing QRB

Are there any typos in the Username and/or Passkey?
Is the Username/Passkey combination qualified for the QRB?
Are any of your clients producing errors which may have caused you to fall below the 80% WU return rate (Check)?
Are you finishing the WU before the Timeout date?
Is the Client properly configured?

Downloading/Uploading WUs

You are connected to the internet
Your security application isn't blocking F@H connections. If it is, please create an exception
For more information, please see this topic: Troubleshooting F@H Server Connectivity Issues (Do This First)

Web Control Issues
If the Web Control can't connect to the FAHClient, possible reasons are:

FAHClient isn't running. Please ensure that it is.
Browser isn't supported. Make sure that you are using the latest browser version
Sandbox limitations of JavaScript is preventing a remote connection

Advanced Control Issues (Local)
If the Advanced Control can't connect to the FAHClient on the same system, possible reasons are:

FAHClient isn't running. Please ensure that it is.
A security application might be blocking the local connection to FAHClient. Please create an exception.
Make sure that you meet the minimum requirements for Windows, Linux, macOS

Advanced Control Issues (Remote)
If the Advanced Control can't connect to the FAHClient on the remote system, possible reasons are:

FAHClient isn't running on the remote system. Please ensure that it is.
Firewall is blocking the remote connection. Ensure that the firewall rules permit F@H connections.
Advanced Control (AKA FAHControl) isn't connecting. Ensure that that the Network Profile is not Public
Passwords on the local and remote system is the same. Please ensure that they are the same.
Remote system is using a different version of F@H Software than the local system. Please ensure that both systems are running the same version of F@H Software.
The allow/deny settings might be incorrect. Please ensure that the settings are correct.
