Folding @ Home Instilation Basics
(January 9, 2003)
Note: The below is intended for F@h 3.24. This information is therefore subject to change.
F@H Client Do's and Don'ts
In general, just download this, run it, and don't worry about it. However, if you like to be "hands on" with F@H, please keep in mind:
Each different running copy of F@H has to have its own Machine ID number. If you download each copy of F@H from the web site and install fresh, there will be no problems.
Please don't manually retry to send WUs soon after a netsend failure. The netsend failure means that the server was probably overloaded and retrying will just make things worse.
Console Client Configuration Options
-config
Allows users to change their configuration information. This includes user & team names (reflected in the stats), whether or not to ask before a network connection is made to fetch/send work, set up proxy servers, preferred work unit type (Folding/Genome), process priority, CPU usage requested (5-100%), whether or not to use assembly loops, whether or not to use deadline information, and Machine ID changes.
-delete x
Delete item #x from work queue. This option should only be used if there is a serious error with the current unit that the client does not automatically recover from (e.g. crash-inducing). This should not normally happen, and if it does, we would be grateful if you could send us the FAHlog.txt file from the unit that causes the error.
-license
Displays the end-user license agreement
-queueinfo
Get information on queued work units. Includes for each unit the status (READY/FINISHED/EMPTY), unit type (Folding/Genome), originating server, and date when the unit was received (local time in GMT), as well as deadline if the server sent that information.
-send x
Send result #x back to server. Exits after trying to send unit (successfully or unsuccessfully). Use "-send all" to send all results outstanding. If unit x is not a completed work unit then the client exits without doing anything.
-verbosity x
Sets the output level, from 1 to 9 (max). The default is 3. This option should be used if the user wishes to see more detailed client output, particularly useful if there is a problem which needs to be reported to the F@H client development team.
-forceasm
Instruct the core to use SSE/3DNow assembly instructions if possible, even if it has previously made the determination that the machine may not be handling this well.
-advmethods
Request to be assigned any new Cores or work units.
-local
Use configuration files from local directory. This option has no meaning on Linux, but is vital on Windows and Macintosh for running multiple clients on a machine. It instructs the client to read its config information from the client.cfg file in the current directory rather than, on Windows, from the installation directory specified in the registry, or, on Macintosh, the Library/Folding@home directory. Information such as the user name, team name, proxy information, machine ID are maintained in the client.cfg file. The flag ensures that work does not conflict. Use "-local" only if you are planning on running more than one instance of Folding@Home on the same machine (this is only useful if you are running on a multi-processor machine). Create as many directories as there are processors on the machine, copy the exe files and client.cfg file into each of these directories, run "FAH3Console -local -config" on each and specify unique machine IDs for each directory (under the Advanced Settings option). From then onwards you may run each copy by switching to its directory and running with the -local flag.
-help
Print out the command line flags available and then exit.
Windows Specific
The below options are accepted but ignored by the clients for operating systems other than Microsoft Windows.
-pause
Pause after finishing and trying to send current unit. Allows a user to shut down after finishing a unit, by pressing Ctrl-C, without then getting new work to process. This is recommended if you are planning on shutting down your machine for a long time (e.g. for a vacation), or are planning to un/re-install F@H after finishing the currently processing work unit.
-service
Run in service mode (for programs such as firedaemon). This prevents the client from exiting when it detects the current user is logging out. If this option is used when the client is not run as a service then it will run normally, but will not shut down automatically if the user logs out, and a "Wait for program to close." dialog box will be displayed.
Linux Specific
-freeBSD
For use by those wishing to use the Linux client on a machine running FreeBSD. See our FAQ for details on how to do this, but with this flag, all Cores downloaded will automatically be branded as being a Linux executable.

Link building Company will help you | Simple Website Templates. Every great website and web design needs a starting place or point. Our own newly redesigned website started from a basic template that was heavily modified to suit our needs and the same can be done for you. Using our simple sea website templates on our site you can buy website templates Below is an In-Depth look at the Folding @ Home project:
PROJECT GOALS: Solving the protein folding problem
Understanding how proteins self-assemble ("protein folding") is a holy grail of modern molecular biophysics. What makes it such a great challenge is its complexity, which renders simulations of folding extremely computationally demanding and difficult to understand. (See Scientific Background for more details about what are proteins, why do they fold, why this is so difficult, and why do we care).
Our group has developed a new way to simulate protein folding ("distributed dynamics") which should remove the previous barriers to simulating protein folding. However, this method is extremely computationally demanding and we need your help (see below). We have already demonstrated that our distributed dynamics technique can fold small protein fragments and protein-like synthetic polymers. The next step is to apply these methods to larger, considerably more important and complicated proteins. Unfortunately, larger proteins fold slower and thus we need more computers to simulate their folding. While the alpha helix folds in 100 nanoseconds, proteins just a little larger fold 100x slower (10 microseconds). Thus, while 10-100 processors were enough to simulate the helix, we will need many more to simulate these larger, more interesting proteins.
To achieve a significant speedup, we need lots of processors in a given run. Also, since a single run does not tell us much, we need to simulate several runs (10 runs would be a good start) per protein. Thus, we need lots of processors. By running our client that uses the Mithral CS-SDK, you can lend us your machine for as long as you like. The client allows you to run for as little or as long as you like. Even a single day's worth of running is helpful to us.
WHAT ARE PROTEINS?
Proteins are necklaces of amino acids --- long chain molecules. Proteins are the basis of how biology gets things done. As enzymes, they are the driving force behind all of the biochemical reactions which makes biology work. As structural elements, they are the main constituent of our bones, muscles, hair, skin and blood vessels. As antibodies, they recognize invading elements and allow the immune system to get rid of the unwanted invaders. For these reasons, scientists have sequenced the human genome -- the blueprint for all of the proteins in biology -- but how can we understand what these proteins do and how they work?
RELATIONSHIP TO THE HUMAN GENOME PROJECT
Since proteins play such fundamental roles in biology, scientists have sequenced the human genome. The genome is in a sense a "blueprint" for these proteins -- the genome contains the DNA code which specifies the sequence of the amino acids beads along the protein "necklace."
WHY DO PROTEINS "FOLD"?
However, only knowing this sequence tells us little about what the protein does and how it does it. In order to carryout their function (eg as enzymes or antibodies), they must take on a particular shape, also known as a "fold." Thus, proteins are truly amazing machines: before they do their work, they assemble themselves! This self-assembly is called "folding."
One of our project goals is to simulate protein folding in order to understand how proteins fold so quickly and reliably, and to learn how to make synthetic polymers with these properties. Movies of the results of some of these simulation results can be found here.
PROTEIN FOLDING AND DISEASE: CJD (Mad Cow), Altzheimer's, ...
What happens if proteins don't fold correctly? Diseases such as Alzheimer's disease, cystic fibrosis, CJD (Mad Cow disease), an inherited form of emphysema, and even many cancers are believed to result from protein misfolding.
When proteins misfold, then can clump together ("aggregate"). These clumps can often gather in the brain, where it is believed to cause the symptoms of Mad Cow or Alzheimer's disease.
PROTEIN FOLDING AND NANOTECHNOLOGY: Building man made machines on the nanoscale
In addition to biomedical applications, learning about how proteins fold will also teach us how to design our own protein-sized "nanomachines" to do similar tasks. Of course, before nanomachines can carry out any activity, they must also be assembled.
WHY IS PROTEIN FOLDING SO DIFFICULT TO UNDERSTAND?
It's amazing that not only do proteins self-assemble -- fold -- but they do so amazingly quickly: some as fast as a millionth of a second. While this time is very fast on a person's timescale, it's remarkably long for computers to simulate. In fact there is a 1000 fold gap between the simulation timescales (nanoseconds) and the times at which the fastest proteins fold (microseconds).
A SOLUTION: DISTRIBUTED DYNAMICS
To solve the protein folding problem, we need to break the microsecond barrier. Our group has developed a new way to simulate protein folding which can break the microsecond barrier by dividing the work between multiple processors in a new way -- with a near linear speed up in the number of processors. Thus, with 1000 processors, we can break the microsecond barrier and unlock the mystery of how proteins fold.
WHAT HAVE WE DONE SO FAR AND WHERE ARE WE GOING?
Folding@Home 1.0 has been a success. During the one year period from October 2000 to October 2001, we have folded several small, fast folding proteins, with experimental validation of our method. We are now working to further develop our method, and to apply it to more complex and interesting proteins and protein folding and misfolding questions.
*note* (the post then goes into details on where you can learn more, and includes hyperlinks to that Forums Folding Topic....I'll skip that part, consult the Folding Topic here, you'll find the same info... )
