Guru3D Folding@Home Information/Help Thread

This thread is to help new members and the uninformed users about Folding@Home and supporting their team, The Guru Of 3D.

(Taken from the Standford University Folding@Home Website)

Our goal: to understand protein folding, misfolding, and related diseases

What is protein folding and how is folding linked to disease? Proteins are biology's workhorses -- its "nanomachines." Before proteins can carry out these important functions, they assemble themselves, or "fold." The process of protein folding, while critical and fundamental to virtually all of biology, in many ways remains a mystery.

Moreover, when proteins do not fold correctly (i.e. "misfold"), there can be serious consequences, including many well known diseases, such as Alzheimer's, Mad Cow (BSE), CJD, ALS, Huntington's, Parkinson's disease, and many Cancers and cancer-related syndromes.

You can help by simply running a piece of software. Folding@Home is a distributed computing project -- people from through out the world download and run software to band together to make one of the largest supercomputers in the world. Every computer makes the project closer to our goals.

Folding@Home uses novel computational methods coupled to distributed computing, to simulate problems thousands to millions of times more challenging than previously achieved.

What have we done so far? We have had several successes. You can read about them on our Science page, Results section, or go directly to our press and papers page.

Want to learn more? You can download our Executive Summary, which is a PDF suitable for distribution. Also, you can learn more by watching recent seminars (Stanford BMI ; Xerox PARC). One can also help by donating funds to the project, via Stanford University

FAQ's

What is this “Folding at Home” anyway?
Folding@Home (abbreviated as FAH or F@H) is a distributed computing project produced by Stanford University that studies protein folding, mis-folding, aggregation, and related diseases. In short, they’re trying to find cures for many diseases. E.g. Alzheimer’s, Mad Cow (BSE), Parkinson’s, CJD, and ALS.

It sounds good, but wouldn't it bog down my computer, by using my systems resources?
The short answer is No, this is because F@H will use only unused clock cycles, it gives up the cycles when a application needs them, here is a article that shows performance impact.

Great! How can I get started?
Well all you need is a computer and a active Internet connection, then download the appropriate client for your machine.

Can I use this on any platform?
Pretty much, yes, current Standford support Windows, Linux, Mac OSX, GPU (both nVidia and ATI), and PS3.

What clients are there and what are the differences?
Well there are many flavors for each platform and CPU type. First of all there is a GUI (Graphical) Client with which you can view a protein as it is folded (for Mac and Windows only, Linux does have a utility to view one), this client is available for both CPU and GPU (GPU is Windows only). Second there is the Console "No nonsense" version which is used on all platforms support (Including GPU too, again Windows only). Last but by no means least there is the SMP Client (Available for all platforms as well), this client, along with the GPU Client, is a special client as the SMP version can utilize up to 16 cores on one box.

Which client should I use?
The GUI (Graphical) Client is by far the easiest to use and setup as it has its own installer and will place the necessary shortcuts. But its simplicity can be taken as a cost as the GUI Client can interfere with some games and may affect client performance and stability which is why the console clients are ussually recomended.

The Text based client shows progress in a simple text based way, also the text based client can be setup as a service regardless of who's logged in. The downside, it is slightly more complex to install and you'll have to make all your own shortcuts.

Which client is faster?
Text > Graphical (By up to 5-10%).

How do I install my client?
Well firstly decide which client(s) you wish to use:

• Single Cpu: Either the Text based client or the GUI client.
• Multi Cpu/Cored Cpu: Can use the Text client or Gui client, but i recommend using the SMP client as you can achieve greater PPD.
• GPU: Use the standard GPU client either Text or GUI.

Note:The Guru of 3D Team number : 69411
Also note: All of the clients listed above (excluding the GPU Client) are available on all platforms.
Also note: Installation instructions are found on the download page, links are located in the "Installation instructions" column.

Download page link.

Flags, what are they? Put simply, flags are used to apply settings when the client is started up (special instructions).

Should I use flags, and which flags should I use?

I recommend these based upon the CPU used and the CPU number:

• AMD Single processor rig: -advmethods -verbosity 9
• Intel Single processor rig: -advmethods -forceasm -verbosity 9
• AMD Multiprocessor rig: -local -advmethods -verbosity 9
• Intel MP/HT rig: -local -advmethods -forceasm -verbosity 9

Break down of flags used above:

• -advmethods: Using this requests to be assigned any new Cores or work units currently be doployed. In effect, you get Gromacs most of the time. But you will still get the occasional Tinker.
  
• -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."
  
• -verbosity 9: Sets the level of output detail that is written to the log file. V-verbosity 4, for example, will output less than -verbosity 9. This can be used later to help determine a problem with folding.
  
• -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.

When setting up I see a option to set core priority, what should I use?

I recommend the following:

• Use low priority on a dedicated folding rig. The core will run at all times.
• Use idle priority on an everyday use rig. The core will only try to run when nothing else is active/use spare cycles.

Note: Idle is the default and is exactly what I would recommend.
Also note: Never change the core priority with task manager as this will lead to undesired results.

What do I do for multiple folding machines/rigs?

Set it up the same way for each machine (depending on client and CPU of course).

Note: When folding with more than one machine you do not change the Machine ID, as this is for multi core/CPU machines.

How do I setup a Multi Core/CPU/HT (Hyper Threaded) Machine?

If the machine has a two physical cpu's (E.g. a Pentium D or a Athlon X2 etc) I you should use the SMP Client for optimum production, but when using a machine with logical CPU's (Hyper Threaded boxes for example) you should not use the SMP Client, you should use two plain Text only clients.

Note: On HT rigs/machines you must set the machine ID to 1 and 2 for each client.

What should I know about my FAH directory?

Work Folder – Contains files your FAH client is currently working on or waiting to upload.
client.cfg – Contains the configuration information for your client. You can edit this with a text editor. If you delete it and are using the text console, the console will run through the configuration process the next time you launch it.
FAHlog.txt – This is the log file of your clients activity. The “-verbosity 9” flag adds details to the log.
unitinfo.txt – This gives you the progress your client has made on the current WU.
queue.dat – This dat file is the que of WUs waiting to be turned in plus info on your current WU.

What is a WU I hear you ask?

WU Means Work Unit (acronym if you will), this is the term used by Standford for a single simulation run.

Are all WU's the same?

No, there are Four (well, three):

• FAHCore_65.exe - Tinker - 100, 200 or 400 frames. They are generally the slowest WUs and the -advmethods flag reduces the number your rig will be assigned unless Stanford releases a new crop.
  
• FAHCore_78.exe - Single Gromacs - 100 frames. Use SSE. They are generally the fastest WUs.
  
• FAHCore_79.exe - Double Gromacs - 100 frames. Use SSE2 They are much faster than single Gromacs on P4 rigs.
  
• FAHCore_A1.exe – SMP Gromacs - 100 frames, most points from here.
  
• FAHCore_11.exe - GPU Gromacs

How long does a WU take?

On fast a rig a WU can be completed in 4 to 36 hours, obviously longer on the slower machines. Standfords points system is setup so that you get more points for the longer/bigger WU's.

How does the scoring system work?
This is how Stanford explains it:

• “How do you determine how many points a work unit is worth? Before putting out any new work unit, we benchmark it on a dedicated 2.8GHz P4 with SSE2 optimizations disabled for the test. We plug the results of this into the following formula:

  points = 3.5 * multiplier * (daysPerWU)

  where daysPerWU is -- no surprise -- the number of days it took to complete the unit.”

GPU Client scoring:

Points are determined by the performance of a given machine relative to a benchmark machine, similar to the CPU client benchmark process. Before releasing any new project (series of work units), we benchmark it on a dedicated computer with an ATI Radeon 3850 GPU (512 MB, 320 Stream Processors), running in a Dell Inspiron 531, with a 2.16 GHz dual core AMD 64 X2 4000+.

My current WU is corrupt, How do I delete It?

1. Close FAH
2. Delete the Work folder and queue.dat file in your FAH directory
3. You may also need to delete the FahCore_XX.exe file(s) so the client can re-download that too (recomended).
4. Restart FAH

My log file says I can’t send/receive WUs, What do I do? Not allot really, if you are certain its not your end then it may be Standford's servers, the best thing to do is check they're servers status and wait until fixed.

Note: You can check the status here.

How well will my computer(s) perform at F@H? Well the best way to work it out is checking out these links (below). These will help you determine your PPD (Points Per Day) and time to run a simulation.

Also check our new Guru3D Points Per Day Index and if you can please contribute.

• Guru3D Points Per Day Index
• FahInfo.org

How much bandwidth does F@H need? It will use 1-10mb (approximately) depending on the WU's size.

Time estimates for a average WU (5mb), based on upload speeds:

• 22kbit/s : 38 minutes ~
• 128kbits/ : 6 Minutes ~
• 256kbit/s : 2 Minutes ~
• 448kbit/s : 1 Minute and 40 Seconds ~
• 512kbit/s : 1 Minute ~

Obviously higher speeds equal less time.

My work unit wont upload, why?

Your WU may not upload if you have configured your F@H settings wrong or Standfords servers are down, again you can check the status here.

How can I check my score?

You can check your score at either Standford's site or the Extreme Over Clocking Folding at Home stats.

Standfords Stats page: The Guru or 3D Teams Stats.
EOC Page:The Guru of 3D Stats page.

Note: when you finish a work unit it may take 1 hour to a day to update your rank and statistics. Don't worry

How do I monitor multiple rigs?

For this you will need a application, any of these work:

• FahMon (My favourite, also can watch across networks).
• Folding Observer (Good for mac use)

Note: Currently the other Applications sites display a 404 error indicating there maybe no support for them.

That is the end of the main issues and questions asked.

SMP on Vista (Same will apply to GPU Client/GUI/Text based)

To begin the installation you must do this:

To begin the installation you must do this:

• Enable the administrator account, as this should help simplify the installation process. Also ensure there is a password on the account. (if your main account is the admin account then you must have a password, and including non-admin accounts, otherwise it will not work).

Installation:

• Log into the account that will be folding.
• Now make a folder in C: call it FAH for example (C:\FAH).
• Download the latest SMP Client (Or gpu if your using gpu).
• Double click and install to the directory we've just created (C:\FAH).
• Now go to the directory C:\FAH and right click on "fah.exe" and make sure its being ran under admin.
• Now double click on install.bat and follow that, password and username, then it should say:
• if it does, then your almost there!
• Now, reboot and login back to the folding account, and naviagte to your FAH directory in C:\ and double click fah.exe and enter the details and et-voila!

GPU Client Section

Quoted from the ATI GPU2 FAQ (can apply to nvidia client too!)
What about multi-gpu support and the -gpu switch?


Running multiple GPU2 clients, one client each on multiple GPU cards, is supported through the -gpu x command line switch. The setup is similar to running multiple SysTray CPU clients.

• Copy your \Application Data\Folding@home-gpu folder to a new folder \Folding@home-gpu2 (\AppData\Roaming\Folding@home-gpu in Vista)
• Create a new shortcut for the first client, and be sure to use the correct Target: and Start In: information. Note that one has to be very careful with shortcuts, and in particular, make sure that the "Start in:" field is set correctly. If you are having problems with automatic core upgrades, it is likely that your short cut is not set up correctly.
• Edit the shortcut properties to add the -gpu 0 switch to the end of the Target: field.
• Create a new shortcut for the second client, and be sure to use the correct Target: and Start In: information.
• Edit the shortcut properties to add the -gpu 1 switch to the end of the Target: field.

Except for the different -gpu x switch, the Target: field in both shortcuts will point to the same FAH executable. The Start In: field for each client will point to the two different \Apps Data\FAH folders. The Target: and Start In: fields for a SysTray client are explained in more detail below.

The display must be active on the GPU card you plan to use, and –gpu 0 will select the first board, –gpu 1 will select the second board, -gpu 2 the third board, and so-on. You will need to disable crossfire for multiple boards to be detected. You will also need to use different Machine IDs for each client. Currently, only one client is supported on a 3850X2 or 3870X2.

Notes regarding use of the GPU Clients:

• Its imparative to use the latest drivers with Folding At Home on the GPU, this is because even though its supported well, its still more sensitive to errors. Much like the SMP client, its best to nurse it whilst you learn to understand its ways.

I'm trying to set up the GPU client and I ran into problems... when I install the dot MSI versions it just says cudart.dll is missing and crashes, the folder doesn't contain it. The zipped version contains it and works fine but doesn't appear to have any sort of GUI and typing into command prompt is annoying.

Simply copying the cudart.dll into the folder of the GUI version worked. I just figured I'd post this for anyone else who ran into the same problem, the error is literally what it says, just a dll missing.

I was going to run the CPU client as well at the same time but it seems the GPU client takes a chunk of the CPU resources anyway.

Edit: It seems it uses a lot of CPU resources for the display, with that disabled there should be no issues running a CPU client at the same time as the GPU client it seems. CPU + GPU + PS3, that oughtta do something.

Edit again: I might as well state what's written elsewhere, the command line versions apparently work faster. I'm running those now.

[J_J_B]

EDIT... possible solution:

Found the following info which indicates my suspicions below may be correct. The use of a single HDMI output and two DVI outputs (one per card) should enable 4-GPU folding for two GTX 295 cards in Vista x64.

http://foldingforum.org/viewtopic.ph...7874&start=180

I have a single HDMI to DVI cable adapter at home so I'm going to test this evening to see if two DVI outputs plus one HDMI connection will bump me up to 4 GPUs.

--------------------------------------------------------------------------

EDIT... RESULTS:

That did the trick. I have a single analog monitor using a DVI-to-DSub adapter on the DVI output furthest from the MB of what I'll call card 2 (PCIe x16 slot #2... furthest from the CPU). Card 1 has a DVI monitor on the DVI output furthest from the MB and an HDMI cable attached to the HDMI output. All 4 GPUs are now folding. (see "EDIT... TIP..." below)

I use a BenQ G2400WD monitor at both my home and work offices and carry my PC with me between each office (it's a SFF with a big aluminum handle on the top). It turns out this monitor is perfect for folding on all four GTX295 GPUs because it has DVI, HDMI, and VGA inputs, thereby fulfilling the need to have two DVI outputs (one with the DVI-to-DSub adapter) and one HDMI output connected.

In a 68 degree F room the GPU temperatures are running up to 74 degrees C in my case (pun intended). In a 63 degree F room the temps rarely exceed 70 degrees C. This is with the card fans running at a 100% duty cycle via RivaTuner. The system was pulling nearly 600 watts with 3 GPUs plus the CPU folding. With the addition of the 4th GPU the system is now pulling up to 640 watts. The system pulls about 360 watts at rest. Watt meter is a cheap dongle-type thing from Lowes with +- 10% accuracy above 1 amp, intended for measuring loads when conidering generator sizing.

A snapshot in time:

GPU 0: 6770.94
GPU 1: 6912.00
GPU 2: 6840.74
GPU 3: 6912.00
CPU: 714

Total Estimated Folding Rate: 28149.68 PPD

Not bad for a small-form factor machine. CPU usage is at 22%. Plenty left to do some work and run a virtual machine or two.

--------------------------------------------------------------------------

EDIT... TIP...

Re-enabled SLI today to play a little Crysis. When the fun was over I once again disabled SLI and extended the desktop to both the analog and HDMI monitor but I couldn't get the 4th GPU to fold as it had been... "Unstable Machine" messages in the FaH logs.

I went back to the drawing board, wondering what could be different. Then I starting questioning why I only ever needed three monitor connections to fold on 4 GPUs before. It was then that I realized that I must have had the PhysX GPU Acceleration setting enabled. I re-enabled that option and all 4 GPUs began folding again.

Enabling PhysX GPU Acceleration seems to activate the "4th" GPU (who knows which one it actually is). That is, the one I don't have a monitor connection on.

--------------------------------------------------------------------------

Original Post:

I've been trying to get all 4 GPUs on my two GTX 295 cards to fold. I was able to get three to fold easily but what I'm reading on the net is that only 3 GPUs of a quad GPU configuration will fold under the Vista or Windows 7 operating systems. Some folks feel it is a problem with the operating systems while others feel it's an issue with the nVidia drivers for these OSs. It was noted by some that downgrading to Windows XP (not an option for me) permitted folding on all 4 GPUs.

I thought I'd ask here just to ensure I'm allowing the correct information to filter through these eyes.

Note that I also see a 5th and 6th display output in Windows' Display Properties, which must represent the HDMI output port of each card. I currently have a monitor attached to each of the four DVI outputs, although I only needed to have one monitor connected to the second card (in addition to the primary monitor on the first card) to fold on 3 GPUs. Do you think I may need to attach monitors to the HDMI outputs as well?

[aircool]

I noticed but thats purely for the GPU client, so it is valid.

How do you decide the credit value of GPU work units?

[Neo Cyrus]

I'm not completely sure why this is happening but my CPU client for the past 2 days has been unable to send it's completed work:


It takes a long time to complete one workload on a CPU, even on a 4GHz C2D, so I'm not too keen on starting up the CPU client again if this could happen again.

[aircool]

Long time, using an SMP client it shouldn't take long at all (unless you are?).

I'd imagine there is no work units left to complete on the server or they've stopped the classics.

[Neo Cyrus]

Hmm I could have sworn it was saying it failed to send it's completed work before which is why I posted a screenshot but didn't read what it said this time, lol. As for now it is as you say, it seems like there is no more work to be done for now through that client.

Edit: Can anyone confirm if there is no more work or if there is a problem on my end?

[J_J_B]

My CPU client (not SMP) has been downloading and working on new WUs nearly continuously this last week. The current WU is 17% complete and the ETA is 12hrs 11mn (Gromacs, 755 points, PPD=1228.47, Downloaded 2hr 34mn ago).

[Neo Cyrus]

I'm not sure what to do here, I was previously using the normal client and I go that error. It might be the specific server it's trying to connect to. I set up the SMP client (which was annoying) and I get the same error. My GPU and PS3 clients have no issues though.

Edit: As I guessed something whack was going on with my firewall settings and now everything works.

Even with the SMP client running it only uses up 50-60% of my CPU's resources and that's with everything else I have running as well. Maybe I did something wrong...

Edit again: Sigh, I should have read the fine print, it requires -smp to be added to a shortcut to run in SMP mode, ugh.

[J_J_B]

Neo: It might not be you... I checked my CPU client about an hour ago and noticed that FahMon had flagged it red. It has been unable to acquire an additional work unit for several hours.

Question for all: (answered - see below edit)
Should I risk running the SMP client rather than the standard, graphical CPU client? I ask because I read somewhere that hyperthreading should be turned off when using quad-core processors and that is something I don't wish to do. I'm also running 4 GPU clients on this same box and I wouldn't want the SMP client to slow down those clients to any appreciable extent...

EDIT:

Well, I jumped and installed the SMP Client - didn't bother to disable hyperthreading or anything but everything seems to be working fine anyhow. Installation went smoothly just like the other clients.

Can't say I'm impressed performance wise... but I guess I'm spoiled with the great performance of the GPU client. I have it set to "low" priotity (rather than "idle") with a target CPU utilization of 90% and 2000 MB allocated. The first downloaded work unit was an "SMP Gromacs" one with 1760 points. It's proceeding at a rate of 1825.50 PPD at the moment and looks as though it's going to take about 24 hours to complete. It doesn't seem to be slowing me down any here so I'll let it run from now on along with the 4 GPU clients and one standard x86 (graphical) client. That's 6 clients folding on this single box.

I also have a virtual machine running (my "work" machine) and it is still speeding right along. Actual CPU utilization at this time is 56%. Memory utilization is at 42%.

[natiss88]

hi guys..I'm new..

i've just joined your team with gpu client.

i'm pleased to be in your team.

or better, OUR team

bye

[yoyo69]

Welcome to the Fold natiss88

[sykozis]

getting ready to start folding on a GTX275 now...lol NEXT graphics card....lets see how long THIS card lasts...

[yoyo69]

I think you will enjoy the GTX275

[sykozis]

I am so far....it's actually working properly!!!

Had people in another thread tell me to disable Stereoscopic 3D on my GTS250....but it didn't fix the issue I had. This is what it was doing...

[IgiPop1981]

i'm obviously missing something...i see a SMP client would be ok to use on my comp as it has 4 cores. however, with all the help and instruction you give here - it would not hurt to actualy link to particular files when mentioned in text (if possible). thing is, i cannot find SMP client for WIN, only ones ofered are for linux..i see some exe files listed up there but fudge me if i can find those..
thanks in advance for any info!


edit: found it trough another forum/link

[aircool]

Yeah its not that hard to find, just scroll down to the high performance clients link.

[IgiPop1981]

yea, but now i need to do smth about the error and not wanting to work...

[IgiPop1981]

ok, followed some instructions from here and there and got it working with all 4 cores
one thing i'm not sure about tho - completed 0 out of 250000 steps? when i last tried i said 500k steps and downloaded a different exe to work with. now it's a1...
well, i guess if it's working at all it's ok
see ya!

[yoyo69]

Use FahMon to monitor the work progress,

also u might want to check on your log file to see if you are getting error reports.

[Vinn3H]

Hello,

Last night i sucessfuly started running 2 GPU client consoles (one per card)

Im running 2 x gtx280's and the console is really stressing the cards, i have set both GPU fans to 100% and the core's will sit around 70 - 75 deg cel (with 2 x 120mm fans at full speed, one at the underside of the case and one on the side panel thats directly in between both the cards) the last thing i want to do is cook the cards. (i also have 2 x 120's at top of case, 1 x 120 at the front and 1 x 120 at the rear) case is a coolermaster RC 690.

My question is:
Is there a way of throttling back how much of the GPU core and Shader is used by the folding process? from memory durring the console setup there was a question about CPU usage, but im not sure if that will apply to the GPU cores. also, to have all the fans @ 100% at night while PC is in my room is a bit of a bugger...

Cheers man, thats has helped a little bit, core now sits around 60 - 65 deg cel. but i have set it up so it uses an idle of 30.
