When the Nvidia 295/296 driver was replaced about 6 months ago, I expected the numbers of failures on GFN tasks to drop. For a while, that happened, but errors are on the rise again, and it's not clear why.

There's computers that fail every single WU running WR tasks using GeneferCUDA.

To be sure, running a WR-sized task is inherently difficult and prone to errors. However, the vast majority of errors occur within the first few seconds, or, at best, within the first hour or two.

It's been difficult to figure out what the root cause of the problem actually is because it doesn't occur on any of the developers' computers, and nobody who does have this problem has spoken up and asked for assistance.

The result is we have several theories, but no real answers and no place to test possible solutions.

So if you're having trouble running GeneferCUDA, I'd like to know about it. We need people who are having problems to describe what their environment is like and to test possible solutions.

I had three errors this weekend which were due to the GPU being overclocked; fine for sieving but verboten for GFN.

I have yet to get a successful GFN262144 unit on PRPnet with my laptop's GT540M. It runs for a bit, but crashes with the typical error we see from on overclocked card. The same card runs both Wieferich and Wall-Sun-Sun without error.

GT 540M @ stock clocks, ASUS i7-2670QM w/ 8GB, Win7 Home Premium 64-bit.

I run a GT650M on my laptop with the latest CUDA drivers.

The laptop runs Windows 7 ultimate 64bit with 16 GB of RAM (i.e. quite standard).

Every Genefer (World Record) v1.07 (cuda32_13) task has an error at present.

Sorry, I should have been clearer.

The typical overclocking/overheating error "MaxErr exceeded: 0.500 > 0.450" is not the problem here. I'm looking for hosts that consistently produces errors with a different type of error. The MaxErr errors we know how to correct (by either slowing down the GPU clocks or increasing cooling.)

In particular, if you're getting BOINC error 127 or seeing cuFFT error 6 in the stderr output, those are two of the error types that I'd like to see fixed. (As well as any others.)

Every Genefer (World Record) v1.07 (cuda32_13) task has an error at present.


That's what I'm looking for. :)

Are you willing to do a little manual work to help fix this? It will mostly involve running the GeneferCUDA program manually from a command line to see what works.

If so, copy the GeneferCUDA executable program from your "C:\ProgramData\BOINC\projects\www.primegrid.com\" directory to a new directory so it won't accidentally break anything in BOINC. The program is called primegrid_genefer_2_3_0_0_1.07_windows_intelx86__cuda32_13.exe but I'd suggest changing the name to GeneferCUDA.exe after you copy it, for simplicity's sake.

You'll also need to copy the cufft32_32_16.dll and cudart32_32_16.dll files to the new directory.

Then, from a command prompt (aka "DOS box"), change your directory to the new directory where you put those files and try running these commands. BOINC (or anything else) should not be crunching on the GPU when you do this.

geneferCUDA -q "1234^524288+1"
geneferCUDA -q "1234^4194304+1"


You don't need to let them run to completion; I just want to know if they fail after a few seconds the way your BOINC tasks fail. If they appear to be running correctly, you can interrupt them by hitting Control-C.

If it's running correctly, you'll see something like this:

Thanks, that's very helpful.

That's what I was expecting to see, but I don't yet understand why it's happening. It's not a general failure, since it's working on the short tasks. The only real difference between the two is that the longer tasks use more memory. That's what's confusing, because your system, with 16 GB on the CPU on 2 GB on the GPU should have more than enough memory -- a LOT more than is needed.

I need to think a little about what could be causing this.

Can you also try:

geneferCUDA -q "502468^1048576+1"


I'm not yet sure what the problem is, but we'll be switching the short tasks from N=524288 to N=1048576 in the next few weeks, so it would be useful to know if the problem will affect the new short tasks.

Thanks!

One of the differences between your computer and mine is that you're using the 306 video driver and I'm using 285.

So I installed 306. That produced no noticeable change -- I still can't replicate the failure that you, and others, are seeing.

Looking at some of the results out there, these errors seem to primarily be occurring on the new 6xx Kepler GPUs. However, they're also occurring, to some degree, on older cards as well. Although the implication is that it's a problem on the Kepler GPUs, it's not conclusive.

Is there anything "unusual" running on your computer that might be using the GPU for something? If not, I'll try rebuilding GeneferCUDA with newer CUDA toolkits. Perhaps that will solve the problem; there could be a problem with the older FFT libraries running large transforms on Kepler GPUs. That's pure speculation, however.

I've resisted using a newer CUDA toolkit because the older 3.2 toolkit is faster than the newer toolkits.

This runs OK.


That's very good news. At least the new n=20 short tasks won't have a problem.

There is nothing else running on the GPU AFAIK.


Ok, then it's a probably a problem running the 3.2 cuFFT libraries on Kepler. Or at least I hope that's what it is. Right now I don't have any other ideas.

When I get a chance I'll build a version with the 4.2 toolkit. And if that doesn't work, there's a 5.0 toolkit too.

Do you have firefox running? It has a feature where it uses the GPU to accelerate the rendering. I have seen it hamper with running CUDA (albeit under Linux).

Try closing all firefox windows and running the failed test again. Admittedly, this is a long shot.

PS:- To prevent FF's use of GPU, change the "layers.acceleration.disabled" to true (about:config)

A review of the results in the database shows that the problem does not apply to all Kepler GPUs. There's successfully completed WR tasks on Kepler GPUs, although not a lot, and none on a GT 650M. That last part probably isn't that surprising, however.

Could you try one more thing for me? Reboot the laptop, and then try this command without doing anything else on the laptop (especially opening a browser or email client.)

geneferCUDA -q "1234^4194304+1"


Also, does the laptop have any settings (possibly in the BIOS or the Nvidia control panel) that set how much memory is allocated to the GPU? If so, what is that setting?

Thanks,
Mike

Mike,

Are these errors occurring only/mostly on laptop GPUs, or are they common on desktop GPUs as well?

I had two WR tasks fail a few weeks ago (here and here) on a restart (two days apart) with the same message: "cuda_subs.cu(761) : cudaSafeCall() Runtime API error : the launch timed out and was terminated."

This box is running Lubuntu 12.04 and has two 570's. Drivers are reasonably up-to-date (> v. 300). It has at least 1 validated WR task in the DB. Clocks are at stock. Regarding the "timed out" business, it is almost certainly true that the CPU was fully utilized running other BOINC/PG tasks at the time. Maybe a GPU needed the CPU to do something within a certain time but the CPU was too busy to respond? Is there a timeout parameter that can be increased? Just guessing here...

That looks like a transient error that's beyond Genefer's control. There's a whole lot of external events that can break a CUDA program, and there's basically nothing the program can do to prevent them from occurring. I need to think about this a bit; I may need to build in a way to detect this and restart from the last checkpoint after a delay, rather than just failing.

When the Nvidia 295/296 driver was replaced about 6 months ago, I expected the numbers of failures on GFN tasks to drop. For a while, that happened, but errors are on the rise again, and it's not clear why...


...The result is we have several theories, but no real answers and no place to test possible solutions.


I realise that you might have considered this already, as I remember all the fuss with the 295/296 drivers; but I noticed that Windows Update recently pushed the latest Nvidia drivers on me. It could be irrelevant, and I realise that there's been no issues reported with the 306.97 drivers, but the results of a user being completely passive in the driver update process, or always updating their drivers to the latest version, means a mass synchronised change from:

295/6>whatever the version number was in between>306


...and that seems to tally perfectly with

Loads of GFN errors>the situation improving>the situation getting worse again


I realise that's a very simple and basic way of looking at things, it's just a thought after I noticed that Windows Update was pushing new Nvidia drivers on me. Also, the % of users who either upgrade to the latest drivers manually, or let the Nvidia software/Windows Update take care of it for them, must be a significant one. A lot of people also might not realise that Windows Update has changed their Nvidia drivers, having deliberately told the Nvidia software not to do it because they're sticking with an older version. Maybe it's a far more complicated issue, just thinking aloud really.

I think there have been three drivers released in the Kepler era: 301, 306, and 310.

There's no correlation that I can see with any particular driver and increased errors, although there does seem to be a correlation between Kepler GPUs and increased errors.

But not all Kepler GPUs produce errors, and the errors are not limited to Kepler GPUs.

I personally have switched to the 306 driver without incident -- but my GPU is a 460.

It seems that every entry in my task list here at PrimeGrid with Application = "Genefer v1.07 (cuda32_13)" has Status = "Error while computing". The list includes entries back to 02 October 2012 for four computers. I have found no record of successful completion of even a single Genefer task on any of these machines.

Typical output is:

Stderr output

<core_client_version>6.10.58</core_client_version>
<![CDATA[
<message>
process exited with code 127 (0x7f, -129)

<stderr_txt>

</stderr_txt>
]]>


I see that you specifically refer to the World Record (WR) tasks, however, none of my entries are annotated to indicate they were WR tasks.

All four machines in question are similarly but not identically configured. Links to the computer information pages and an errored task for each are included below. Although the GPU's (EVGA GeForce GTX 670 FTW and EVGA GeForce GTX 460 SuperClocked 1024MB EE) are factory overclocked, I have not further overclocked them and the Core i7's are not overclocked. All four machines are running CentOS release 6.3 (Final) with NVIDIA Driver Version 304.60.

Although I use Google Chrome predominantly for browsing, I do have Firefox installed and I use Mozilla Thunderbird for email.

Do you have the linux 32 bit libraries installed? GeneferCUDA is a 32 bit app, and it won't run on 64 bit linux unless the 32 bit libraries are installed.

If you do have the 32 bit libraries, then the next question would be what happens when you try to run GeneferCUDA from the command line?

I did not. So, on one of the machines, I installed
    nvidia-x11-drv-32bit-304.60-1


which also required installation of the following as dependencies.

    glibc-2.12-1.80
    libX11-1.3-2
    libXau-1.0.5-1
    libXext-1.1-3
    libgcc-4.4.6-4
    libxcb-1.5-1
    nss-softokn-freebl-3.12.9-11
    zlib-1.2.3-27


If you do have the 32 bit libraries, then the next question would be what happens when you try to run GeneferCUDA from the command line?

After installing the packages above, restarting the machine, and using Boinc Manager to suspend all running tasks while the boinc-client service continued to run...

So, the resolution in my case may be as simple as setting up a soft link or renaming a file. I won't know until I've tried. I will post back here if I stumble upon a solution for my case.

Thank you for your patience and assistance; and for all that you do to enable the rest of us to contribute to the PrimeGrid cause.

Mike,

If I'm barging into the wrong thread with this, I'll go elsewhere and post this...

I'm on Mac OS X 10.7

I previously had this problem where the GeneferCUDA would sit in a 'ready to work' state and never run. Even when the computer is rebooted and BOINC is the only thing running. You changed something on the server when I reported this before.

I had to reinstall the OS due to my previous graphic card dying on me. The fans locked up. The vendor has replaced it with a newer model, and my OS wasn't friendly to just swapping out the old card for the new card.

Anyway, I'm back to 'ready to work' state, even though the log shows the card being recognized.


What do do?

I had to reinstall the OS due to my previous graphic card dying on me. The fans locked up. The vendor has replaced it with a newer model, and my OS wasn't friendly to just swapping out the old card for the new card.

Anyway, I'm back to 'ready to work' state, even though the log shows the card being recognized.


What do do?

The changes that Rytis made on the server back then are still in affect. It wasn't a specific fix for your computer; it was a misconfiguration that affected all Mac computers trying to run GeneferCUDA. So that's not likely to be the cause of your current problem.

The most likely cause is your "new" computer -- or at least the new BOINC installation on your computer -- is using the wrong venue. Check and see what venue the computer is assigned to, and then make sure that venue has the correct projects selected (or change the computer to another venue if another venue has the correct settings.)

Seth,

A few questions for you.

You're trying to run Genefer on the computer with the 560 Ti, correct? (The 8400 GS can't run GeneferCUDA.)

It looks like you've had a long GeneferCUDA task running on the 560TI since November 13th. Is that running correctly? Or is the problem that the task has been sent to you, but it won't start?

Mike

Mike,

Thanks for your assistance in this matter. It's curious you say the 8400 GS can't run GeneferCUDA. Currently it seems to be running on a different Mac OS X machine--

Tue Nov 13 11:35:59 2012 | | NVIDIA GPU 0: GeForce 8400 GS (driver version 262661, CUDA version 4020, compute capability 1.1, 512MB, 22 GFLOPS peak)



On that machine, I have it working on a GeneferCUDA work unit right now. It's on the original machine with the 560TI that the work unit is stuck in a 'ready to start' state.

I've also reset the project and gotten another work unit and it remains stuck like that.

As for the venue, I don't think that's a factor here. I don't have anything specified in my account computing preferences for work home school.

thanks!

I believe you're mistaken. :)

The 8000 series lacks the double precision hardware required by GeneferCUDA. Furthermore, looking at the database, there's no GFN tasks assigned to that computer.

(If you were running it on PRPNet, it might appear to work, but what would actually happen is that GeneferCUDA would fail due to the GPU being below CC 1.3, and the GenefX64 would run the calculation on the CPU. On BOINC, the server will refuse to send a GPU work unit to a computer with a 8400 under normal circumstances.)

It's on the original machine with the 560TI that the work unit is stuck in a 'ready to start' state.

I've also reset the project and gotten another work unit and it remains stuck like that.


Is there any other BOINC task running on the GPU?

Michael,

Thank you for your assistance in this matter. I apologize for wasting your time. Problem Existed Between Chair and Keyboard.

The 8400GS card is working on PPS Sieve tasks. The 560TI is now crunching Genefer after I added a check to a box in one of the UI panels.

Thanks,

Seth

Michael,

The machine with the 560TI completed the genefer task, then wouldn't download another one. I update the BOINC client. It downloaded a task and within one minute error-ed-out. Logs pasted below.

This card is not overclocked and the cooling should be sufficient. No conditions have changed since it finished the last genefer wu.

AH!!!!!!!!!!!!!!!!!

You may have just solved a HUGE mystery. Thank you.

When you re-installed BOINC, your installation settings (perhaps "run in a protected environment"?) caused BOINC to run inside a VM. Most VMs can't run CUDA at all; this one clearly can but I'm guessing it's not doing it exactly right and that's causing the app to fail.

Can you try re-installing BOINC in such a way that it doesn't use the VirtualBox VM? I think that will solve the problem. At least I hope it solves it.

Michael,

Well, I hope we can get something figured out about this Genefer app situation..

I searched about 45 minutes worth of google, and couldn't find the solution you're recommending. VirtualBox has lots of people talking about how to enable it with Boinc, but nothing about how to disable it.

Do you have any resources you can point me at? I've already deleted my 7.x version, installed the 6.x version, and reverted back to the 7.x version. Under the 6.x version, you can see the log below. Computation error.

thanks,

Seth

@Seth Johnson:

You can not revert back from v7 to v6 due changes on the client_state.xml file. You need to install a fresh version of BOINC v6.

Seth,

It looks like Virtual Box is unrelated to the problem.

Can you try running a WU manually, just to see if it fails the same way as it does when running automatically when running under BOINC? You can use the following command line:

primegrid_genefer_2_3_0_0_1.07_i686-apple-darwin__cuda32_13 -q 8042^4194304+1

You'll need to either copy the executable to another directory, or download it directly from http://primegrid.com/download/

Of course, when you try that, no other program should be running on your GPU.

Thanks!

(In addition to the executable, you may also need to copy the cudart and cufft libraries. I'm not 100% sure how the Mac distribution is put together.)

For the Mac version, you need the following library files:

libcudart.dylib
libcufft.dylib
libtlshook.dylib

I'm having exactly the problem described. WR (and only WR) dies within a few seconds of starting. I have a GTX 670, I'm running linux, my driver version is 304.51 (the most recent drivers to show up in the repositories as of yet).

Where does it expect libcufft.so.3 to be? Right now when I try to run from the command line it gives errors about not finding libcufft.so.3, even when I also download libcufft.so.3.32bit (and even if I rename that to drop the .32bit). I have .so, .so.4, and .so.4.2.9 installed in /usr/lib/x86_64-linux-gnu/. Symlinking the .so.3 in those places didn't help.

Er, that would be because I don't have the 32 bit nvidia libraries, wouldn't it? Unfortunately it doesn't look like the Mint/Ubuntu repos have them, so I am going to have to go try to find them and get them to install alongside the 64 bit libraries.

So, I have it in /usr/local/cuda. This is on my machine; ubuntu 11.10. Yes I have two different versions of the SDK installed, and it's a 64-bit machine.

In a shell, after doing this:

setenv LD_LIBRARY_PATH /usr/local/cuda/lib64:/usr/local/cuda/lib

(for "csh", or the equivalent for other shells)

then the command-line version of genefercuda works fine:

% ./genefercuda -q "1234^524288+1" genefercuda 2.3.0-0 (Linux x86 CUDA 3.2) Copyright 2001-2003, Yves Gallot Copyright 2009, Mark Rodenkirch, David Underbakke Copyright 2010-2012, Shoichiro Yamada, Ken Brazier Copyright 2011-2012, Iain Bethune, Michael Goetz, Ronald Schneider Command line: ./genefercuda -q 1234^524288+1 Using default SHIFT value=7 Starting initialization... maxErr during b^N initialization = 0.0000 (0.073 seconds). Estimated total run time for 1234^524288+1 is 1:29:34

>>snip<<

Hope that helps. Maybe if you have stuff installed elsewhere, just setting LD_LIBRARY_PATH to point at it will work. Oh yeah I have driver version 302.17. I originally installed the real nvidia drivers ("nouveau" doesn't support CUDA) with:
sudo apt-get --purge remove xserver-xorg-video-nouveau sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update && sudo apt-get install nvidia-current nvidia-current-modaliases nvidia-settings


Now the updates just come through the normal "update manager" process. The OS at the time of the original install was 10.10 but now I'm on 11.10.

I'm stumped. The only way I can get that particular error is if LD_LIBRARY_PATH isn't set, or is set to some bogus location (i.e. anywhere the library isn't). If you were finding the 64-bit library erroneously, you'd get an error message that ends: "wrong ELF class: ELFCLASS64". The content of your /usr/local/cuda/lib directory looks identical to mine.

I do not believe the presence or absence of the 64-bit libraries matters unless you happen to encounter that, and only that, looking for libcufft.so (see above failure).

Sorry if this is elementary, but you did do:

setenv LD_LIBRARY_PATH /usr/local/whatever

and not
set LD_LIBRARY_PATH=/usr/local/whatever

beforehand? The latter is not effective.

Beyond that, Iain B. will probably have to chime in to resolve this.

And if you use 1234^524288+1 instead it works?

That eliminates the BOINC environment as the cause of the problem, but unfortunately it doesn't really shed any light on what's causing the problem.

I'll let you know soon. I need to touch base with Iain about the next step, which would be testing a newer build of GeneferCUDA.

Followup: My off-the-cuff impression is that there's a much bigger Linux problem here that's causing a lot of the problems.

Looking at the database, that appears have some validity. In general, about 90% of the computers here run Windows. The data confirms that: less than 10% of the successful WR tasks are done by Linux computers. Given that 90% of the computers run Windows, that's not surprising.

What IS surprising is the number of errors -- approximately 45% of all the errors come from Linux computers, which is far in excess of the Linux population.

That gives us something to look at.

it is not just linux the are things happening on the windows side to.

I have started a thread "is boinc running slow?"

in the hope of collecting the weirdness in 1 place.

if some one wants to come up with a better thread name go for it.

every one is tweaking so their equipment will be fastest for the holidays,

I wonder if all the driver and os tweaks may have something to do with this?

It certainly seems likely that one way for Linux users to easily slip up is the frequency of kernel and/or nvidia driver updates... it seems like every other week or so I get one or the other if not both. Maybe dancer42 is alluding to this. If one allows either to occur with a GFN search running, it will crap out, and then the machine will then start trashing units (subject to the time-out delay between each) until it is rebooted. Sadly I messed up and allowed this to happen once a couple of months ago on one box, to the detriment of several dozen "short" units.

I had two WR units die due to "Runtime API error : the launch timed out and was terminated.". I mentioned this earlier in this thread (post 59513). Haven't heard of this error from other platforms, and I still have no idea as to the cause (stock clock; good cooling).

Gary,

I'm not concerned that much with the occasional unexplained error (or series of errors). That's inevitable with GPU computing, since there's any number of transient environmental problems that can occur, regardless of the platform. I was watching the other day as the nvida video driver crashed and got restarted, for example. That, of course, killed the CUDA task that was in progress.

What concerns me are the hundreds of errors that appear to be due to some kind of misconfiguration. If, as you suggest, it's caused by an automatic driver update which doesn't also cause a reboot, then there's little that can be done about that. At least on Windows, when that happens, the driver doesn't get installed until the reboot, so I haven't seen a situation where the driver is left in a state where CUDA can't run at all. Maybe it's different under Linux.

Is there anything else I can do that will give a better indication of exactly what is wrong?


Philip,

Could you download a newer Linux build of GeneferCUDA from here? Try running that from the command line to see if it fixes the problem.

The linux binary in there should be statically linked, so no external libraries ought to be needed.

Thanks,
Mike

According to my experiences with Ubuntu, the weekly sometimes daily updates are a problem. While doing the update a tool called "dkms" checks if kernel-modules have to recompiled. This is nothing unusual and normally not a problem but sometimes it unloads all kernel-modules (also the nvidia ones) and all gpu-units dies within a few seconds.
Here a snippet from updating my Lubuntu11.10 host:

If i want to update my installation, then i suspend BOINC and as second step i shutdown BOINC complettely via '/etc/init.d/boinc stop'. After up-/upgrading my installation i do a reboot and have not crashed any unit in the last years. All errors in the last years were related to driver, cooling and memory errors. Okay i had some application errors but these were mostly linking faults.

The nvidia driver itself is a really big problem for linux users. In older versions you could adjust the clockrates (up and down) via 'bash' or GUI after adding 'coolbits' to the config. This is not possible anymore since a long, long time. All you can do after adding this command is adjust the fan speed and nothing more. Users with factory overclocked cards cannot downclock anything and i am not aware of a linux-version from "MSI afterburner" or any other useful tool available for Windows.

Thanks for that info, Ronald. All that certainly makes running CUDA under Linux more challenging.

Most of the problems we're seeing -- at least the ones that are of concern to us because it's impacting the project -- are either happening to every WU immediately at launch (a configuration error) or within a few seconds while doing the initial calculations, which appears to be due to running out of video memory.

Hi !

Happy New Year !!!
I'm under Linux, and had a problem with genefer cuda, and I stopped to fetch work with it (because of recent OS upgrade).
Now I'm under Linux 12.04 64 bits and before starting to test again a Genefer work, is it possible to see if it cannot crash like said here ?

The description in the beginning of this post is exactly what happened with my previous OS (WU dies immediately or within some hours).

Here is my configuration :
Boinc 7.0.27
GPUs : GT 220 and GT 430.
Driver : 310.19

Here is my configuration :
Boinc 7.0.27
GPUs : GT 220 and GT 430.
Driver : 310.19



Well, to start with, GeneferCUDA can't run on the GT220, so make sure it's running on the GT 430. There's at least a good chance that your problems were due to BOINC trying to run the task on the wrong GPU.

If you can figure out why it's failing on your machine -- that is, what makes your machine different from Linux computers where it works -- that would obviously be of great help. The one thing I can thing of for you to try is to try running GeneferCUDA by itself, without BOINC, in order to see if it's a problem related to BOINC.

It's probably not related to boinc, but because you have two GPUs and only one is capable of running GeneferCUDA, it's possible that BOINC was trying to run the program on the wrong GPU. On the server, we can only send tasks to hosts with suitable GPUs, but once it gets to your computer BOINC isn't smart enough to know it can only run on one of the two GPUs.

If BOINC lanuches or restarts the task on the wrong GPU, it will fail.

Depending on which version of BOINC you're running, there's different methods for manually telling BOINC which GPU to use.

OK, thanks for answering.

That makes sense now. I'll try to make a app xml for PrimeGrid and GeneferCUDA to be sure that the GT 220 does not try to compute those WU (GT 220 is CC 1.2).
By the way, this GT 220 will no more be in my computer in the incoming days (replaced by a GT 640), then I think there will be no problem.

I'll get back here to report if OK or not, then.

I set my host to sleep at a given hour, to save power costs (power is cheaper during the weekend and at night).

On my previous card (gtx 550ti) this procedure never caused a task to fail. However, with the new one, the genefercuda tasks fail immediately upon wakeup.

The card has successfully finished at least five tasks (without sleep) although two of them are still pending, with the "validation inconclusive" tag, other two are waiting for a wingman and the only validated so far is already purged from server.

The card clock is factory oc'ed to 904Mhz. With four out of five tasks waiting to validate, I' not sure if I should use this card during the challenge.

The error that's occurring is the maxErr exceeded error.

I can think of two possibilities:

1) It's the overclocking, same as always. I honestly have no information about whether the same overclocking problem affects the 600 series GPUs, so I can't rule that out. The fact that it seems to only happen after waking up from sleep might be a coincidence, or it may be contributing to the problem somehow.

2) For some reason, the checkpoint/restore process isn't working correctly on your system. This is easy to test. Just stop the task from the BOINC manager, then restart it. See if the same problem occurs.

As for your two inconclusive results, I can tell you that in one of the two, the OTHER computer returned a residual that looks bad. (Sometimes it's easy to identify a bad residual.) With the other one neither computer's result is obviously faulty. Both of those were with your 550 Ti, however.

Then again, if you're concerned about the reliability of the GTX 650 Ti, I'd recommend running the 550 Ti instead. The 550 Ti seems to be about 15% faster than the 650 Ti, based upon your results.

Thanks Michael,

This is easy to test. Just stop the task from the BOINC manager, then restart it. See if the same problem occurs.


Stopping/resuming on boinc does not cause an immediate fail. However, run time goes back to 0:00 on each restart (both with suspend task or boinc restart). This does not happens if the host sleeps/wakes up.

Edit: time reset only happens if suspend is done in the first 3 or 4 minutes (I guess that I suspended before the first checkpoint). After that, it only gets back a minute or two.

I did some debugging with the -t switch. It had no issues up to n=19.

Then again, if you're concerned about the reliability of the GTX 650 Ti, I'd recommend running the 550 Ti instead. The 550 Ti seems to be about 15% faster than the 650 Ti, based upon your results.


The idea was to have both cards running during the challenge... The main drawback is that cpu time rises form <200 seconds to >3000 seconds with both cards running.

The memory clock of the 650 is not oc'd. I downclocked it anyway (this was the issue with the 550ti, as you remember). Let's see how it goes.

Which nvidia driver and boinc version is needed to participate in the Challenge ?

Before I had 7.0.28 icw 3.10.90 but got tired of the 0x000000EA errors.

So went back to 6.10.60 / 266.58 to try but now that doesn't work either.

So who can let me know which driver and boinc version I need to install to participate ?

The latest boinc version should work fine. The 6.10.xx versions should also work.

As for drivers. avoid the 295 and 296 drivers (this applies to ALL CUDA apps, not just GFN). I don't know about the 266 driver, but anything from 285 upwards, except for 295 and 296, should work.

The drivers and the boinc version aren't your problem, however. This is: (Taken from the stderr.txt output from your results)

Starting initialization...
maxErr during b^N initialization = 0.0000 (0.437 seconds).
Testing 23702^1048576+1...
Estimated total run time for 23702^1048576+1 is 13:45:25
maxErr exceeded for 23702^1048576+1, 0.5000 > 0.4500
19:18:16 (1448): called boinc_finish


That's the error you see when your GPU is failing because of excessive overclocking.

Lower the overclocking on your GPU (especially the memory clock) and the errors should go away.

I have a GTX460FTW and a GTX460SC which both run at stockspeed BUT the FTW with lower voltage so now I have upped the voltage from .925V to .950V which seems to have done the trick.
At the moment its running for more than half an hour.
As with GPUGRID, this project needs a bit more juice.

The first two (probably the same computer) are having errors, the third one at the slower speed seems fine.

ALL of them are overclocked. This is from a 460 at stock speeds:

You should be able to eliminate the errors on the first 460 by lowering the clocks, especially the memory clock.

I know. The FTW runs with 1700MHz/1.075V and the SC 1526MHz/.950V and I lowered the voltage of the FW which runs fine on S@H and some other projects but there are some projects that just need more juice and as I said I think increasing the voltage to .950V might be the solution. Otherwise I'll increase it a bit more. The FTW however gets easily very hot.
We'll see but as for now I'm glad its running.

I know. The FTW runs with 1700MHz/1.075V and the SC 1526MHz/.950V and I lowered the voltage of the FW which runs fine on S@H and some other projects but there are some projects that just need more juice and as I said I think increasing the voltage to .950V might be the solution. Otherwise I'll increase it a bit more. The FTW however gets easily very hot.
We'll see but as for now I'm glad its running.


Let us know how it works out. Since this problem seems to correlate directly with heat, I'd suspect that raising the voltage would be the last thing that would help, but you never know!

Please let us know how this works out once a few results have been returned and validated.

Good luck!

OK, thanks for answering.

That makes sense now. I'll try to make a app xml for PrimeGrid and GeneferCUDA to be sure that the GT 220 does not try to compute those WU (GT 220 is CC 1.2).

I'll get back here to report if OK or not, then.

Hi all !

I'm tryng to do a cc_config.xml file that don't use the gpu #1 (GT220) dor genefer tasks, but it use it !

Here is a part of my cc_config file :
<cc_config> <options> <use_all_gpus>1</use_all_gpus> <exclude_gpu> <url>www.primegrid.com</url> <device_num>1</device_num> <type>nvidia</type> <app>genefer</app> </exclude_gpu> [...]

Why, in the hell, is boinc allowing computing GPU on Primegrid/Genefer on GPU#1 ?!!!
I don't understand : there are options for allowing excluding, and it doesn't work !

Try using the full URL:
<url>http://www.primegrid.com/</url>

That's what the master url is defined as, so that's probably what you need to use.

If that doesn't work, unless you have BOTH Nvidia and AMD GPUs in that computer, remove the <type> line as it shouldn't be needed.

Also, in case you run the longer tasks, those have a different name, so you should include that also. You don't want the BOINC client to decide to switch to the wrong GPU 95% of the way through a long task!

<exclude_gpu> <url>http://www.primegrid.com/</url> <device_num>1</device_num> <type>nvidia</type> <app>genefer</app> </exclude_gpu> <exclude_gpu> <url>http://www.primegrid.com/</url> <device_num>1</device_num> <type>nvidia</type> <app>genefer_wr</app> </exclude_gpu>

Thanks for answering so quickly.

I've done what you adviced, but the event log says :

sam. 12 janv. 2013 13:56:11 CET | PrimeGrid | A GPU exclusion in your cc_config.xml file specifies a non-existent application 'genefer_wr'. Existing applications: 'llrWOO', 'pps_sr2sieve', 'llrPPS', 'llr321', 'llrTPS', 'trp_sr2sieve', 'llrSOB', 'genefer'

I think the genefer include the WR part too ?
Well, I don't have set genefer_wr and no more error in event log.
But now (without type NVIDIA fields), it seems that no more Genefer WU is sent to GPUs (#0 or #1).

I leave as this, If one day, it'll work... It'll work on the good GPU.

Thanks for answering so quickly.

I've done what you adviced, but the event log says :


The warning in the log can be ignored. It looks like the BOINC client doesn't know about genefer_wr because either you've never run it on that BOINC installation, or you haven't run it recently. You'll notice that genefer_wr isn't the only application missing from the list.

If you ever do run the long WR tasks, you'll want that exclusion to be in there because it prevents BOINC from switch the task from the new GPU to the old GPU. Considering how long those tasks are -- and the huge investment in time that goes into each one -- you don't want to risk blowing up a WR task when it's almost done.

But now (without type NVIDIA fields), it seems that no more Genefer WU is sent to GPUs (#0 or #1).


Strange, but maybe not surprising. Does it work with <type>nvidia</type> in there?

OK I put the genefer_wr exception in case of I'll do such jobs (but very looong indeed).

I tried with the nvidia type, and it seems to allow computing on genefer, with exclufing gpu #0 and the gpu #1 with <exclude>. It shouldn't allow WU to come if the only capable gpu (#0) is ignored...

But I need to test more to see if the nvidia <type> changing something or not (maybe it's a coincidence).

What is not very cool, is crashing WU to test if the wrong gpu is excluded or not :-/

Lost one more (n=20) w/u to the "launch timed out and was terminated" issue today. Right around the time the w/u reported "error" back to the server, I had the following error messages appear in /var/log/syslog:

Jan 14 19:29:18 eagle kernel: [499855.352657] NVRM: GPU at 0000:01:00: GPU-821e2c27-d950-9072-83d0-35518bbefec2 Jan 14 19:29:18 eagle kernel: [499855.352660] NVRM: Xid (0000:01:00): 8, Channel 00000003


A few minutes later the following appeared in /var/log/Xorg.0.log:

[500331.972] (WW) NVIDIA(0): WAIT (2, 6, 0x8000, 0x0000d6b0, 0x00006704) [500338.792] (WW) NVIDIA(0): WAIT (0, 6, 0x8000, 0x00006704, 0x00006704)


The machine was not in use at the time except for unattended [challenge!] crunching (I wasn't even home at the time). This is with Ubuntu 12.04, nvidia driver 304.64. Clocks are at stock and cooling is good. There are 2x 570 installed. Most Genefer n=20 units run fine.

I know at least one of my teammates has had the same error with almost identical log messages. A web search doesn't reveal much from crunchers regarding these messages, but some gamers report everything from temporary video hangs, jumbled/pixellated screens, up to a hard freeze requiring a system reboot. There are various suggested fixes but nothing seems to work for everyone. Most of the fingers are pointing at "driver bug", but I don't see any real evidence for any conclusion yet.

When I get a chance, I'm going to look at the source code for GeneferCUDA to see if there's a reasonable workaround. Of course the "real" fix likely lies elsewhere, but it would be good to have an alternative to trashing hours of GPU time.

Gary,

Someone reported that they had an error when their came out of sleep. (This was NOT the 295 driver.)

It turns out that the error they got was the same "launched timed out" error you got

Does your computer put the monitors to sleep?

I don't know if there's a relationship there or not.

I've got a new Windows build of GeneferCUDA, thanks to Yves and Iain.

Those of you who have been having trouble running the WR tasks (but CAN run the short tasks), feel free to try this new version using app_info.

You can download the new app from the svn repository.

WARNING: The new build of genefercuda should be considered alpha quality code. It has no known bugs that I'm aware of, but we have not completed testing. In particular, I have not tested it with BOINC.

The major difference is that this version uses a the CPU instead of the GPU to do the initialization. Although this takes a few minutes rather than a few seconds, it greatly reduces the amount of video memory required.

(This version of the CPU initialization is MUCH faster than the original initialization code from 2011. For n=19, the original code took about 5 minutes, the GPU code took less than a second, and the new CPU code takes about 6.5 seconds. At n=22 (WR) it takes about 90 seconds).

This also means we're getting closer to having new CPU apps available. The new framework is stable enough to release this new CUDA app.

***** IMPORTANT!!!!!!! *****

I just discovered that the current "new" build of geneferCUDA on assembla has broken maxErr code, therefore it can't detect when an error occurs. It will happily go and crunch a number way beyond its B limit, and it can't detect when an overclocking problem happens.

To avoid wasting countless hours crunching only to have the result fail validation, please cease using the new app immediately.

In addition, if you're using it with PRPNet (where no double checking is done), please contact me so that I can insure that any tasks you've completed do, indeed, get double checked.

Thank you.

UPDATE

The maxErr bug has been corrected. Feel free to download the new Windows build of GeneferCUDA.

Please see this post for the link, as well as a warning about the testing state of this build.

Thank you for your patience.

Glad to hear it!

This new build is intended to fix the specific error you (and many others on both Windows and Linux) were getting. I'm glad to hear it's working fine for you.

There's another big class of errors we're going to try to address in the relatively near future: the ability to recover from a transient GPU error. For example, in Windows 7, if the video driver crashes, Windows will restart the video driver and the system keeps running.

Unfortunately, any CUDA program running on the GPU does not.

With the new error handling, genefer will wait 10 minutes and then re-initalize the GPU and try to resume from the most recent checkpoint. This will be especially helpful on the long WR tasks: it's not much fun for something like a driver crash to wipe out a week of crunching on the GPU.

The new geneferCUDA that's currently in production already tries to restart after encountering the "maxErr exceeded" error, so if your card's just on the edge of working or not working, you may be able to squeak by now. In practice, however, most GPUs that get that error will always get that error, so it still errors out in the end.
