Message 38989 - Posted: 21 Nov 2014 | 10:47:01 UTC

We had to discontinue cuda 4.2 apps because of some time limit in the executable.
As they were going to be discontinued anyway, we will only reintroduce it if really necessary.

If you were using cuda4.2, update your driver


* Discontinued CUDA 4.2
We need CUDA 6 to properly support the new Maxwell, so I'll be retiring the old CUDA 4.2 build. If you are still receiving version 4.2 WUs, please consider updating your driver to version 343 or above.

Does the driver version have to be quite that high? I'm running cuda60 tasks - successfully, so far as I can tell - with driver 335.28: driver 343 or above would only be needed to support cuda65.

CUDA60 will stay around for the time being, but won't get any of performance updates I am anticipating for CUDA65.

Hi, In Linux (Ubuntu 14.04.1) receive only 8.21-Cuda 60 tasks am using the latest Nvidia driver 340.58 as you can see:

(Fri November 21, 2014 17:09:37 CET | | CUDA: NVIDIA GPU 0: GeForce GTX 770 (driver version 340.58, CUDA version 6.5, compute capability 3.0, 2048MB, 2000MB available, 3693 GFLOPS peak)

As stated in the future ...? Greetings.

We make the scheduling decision on the major version of the driver only. Later minor releases of earlier major versions have back-ported CUDA 6.5 support but we ignore that as it complicates the scheduling code too much.

Hi, Sorry but I do not quite understand the answer .. means that in the future there will be tasks Cuda 6.5 on all OS (Windows-Linux) because only they will be guided and supported by the version of the Nvidia driver ...? Greetings.

Hi, Sorry but I do not quite understand the answer

I don not quite understand your question either:
As stated in the future ...?

What Matt was saying is: they only consider the major drivers introducing new CUDA functionality, i.e. all CUDA 6.5 drivers after 343 are treated the same way (true for older versions as well).

Your 340.58 is obviously too old for CUDA 6.5, but will be fine for 6.0 for a while. Maybe by the point 6.5 becomes appreciably better than 6.0 your Ubuntu folks may provide a recent driver. Otherwise you may want to manually install the driver directly from nVidia.

NVIDIA driver 343.22 is the most recently supported non-beta Linux driver. I have been using this driver and I have no exceptions. A search on the NVIDIA web site for the most recent driver for the non-900 series card will result in 340.58 being the most recent supported driver for 700 series card and lower, however this web page for 343.22 driver (http://www.geforce.com/drivers/results/77844) states this driver supports NVIDIA cards going back to the 400 series, among others.

It would appear NVIDIA web site has not been properly updated to add the 343.22 driver for supported NVIDIA cards, other than the 900 series.

Hi, The version 343.22 is dated earlier, September (at 340.58) and does nothing concerning CUDA only support for the 900 series and solution of some faults and all updates.

The 340.58 driver has support for CUDA 6.5 and thus reflects information BoincManager I earlier post; "(Driver version 340.58, CUDA version 6.5, compute capability 3.0)"

Therefore I insist on asking what the problem is to have tasks GPUGRID Cuda 6.5 on my Ubuntu 14.04.1. Greetings.

Message 39005 - Posted: 22 Nov 2014 | 21:49:00 UTC - in response to Message 39004.

I'm running W10_x64 with a GTX770 and default 340.52 M$ drivers, for now...
Boinc 7.4.27 states that the GPU is cuda 6.5 compatible.
However, the GPUGrid app says Long runs (8-12 hours on fastest card) 8.41 (cuda60).
This is because the app isn't refined enough to adequately distinguish between sub 343 drivers that support 6.5 and those that do not. The reason is that they don't all support cuda 6.5 equally, and Matt cannot code, test and debug for every minor driver release that pops up (for every OS).

I expect there would be more performance to gain from more recent CC cards (Maxwell's) with 343+ drivers and app builds, so if you have a non-Maxwell and a sub 343 driver, don't worry about it, so long as it runs cuda 6.0 (and correct me if I'm wrong).

Hi, Thanks for the comment; I also Boinc 7.4.27 Win 8.1-64 bit and Nvidia 344.75 driver with 8.47 Cuda 6.5 GPUGRID tasks without problem.

Obviously the numbering of the Nvidia drivers on different OS is not the same.

From what I understand it is necessary to install an Nvidia> 343 driver to have 6.5 Cuda tasks in both Windows and Linux ... this limitation creates confusion. Greetings.

So, I have this card:

I understand it will no longer crunch for GPUGrid now, that's right? If I update the driver, will it work?

Many thanks.

Correct. GPUGrid never produced a CUDA version 5.0 application (the exact match for your current driver), so you will have been using the next version below - CUDA 4.2

If you read the first post in this thread, that version has now been discontinued, so there is nothing compatible with your current configuration. If you simply update the driver, you will be able to run the CUDA 6.0 or 6.5 applications - nothing else needs to be changed.

Valter, as Richard said, you are correct; you need to install a more recent driver to use your GPU.

The recommendation is a 343.21 or newer driver so that you can run the cuda 6.5 apps.
From what Matt said, a 343 or newer driver should also support the next (future) app version as that will also be based on cuda 6.5 and might bring a performance increase for some cards...

See this thread,
Please upgrade to DRIVER 334.21 or NEWER

Hi, I had to install the driver for Linux, Nvidia 346.16 Beta to accomplish tasks 8.46-Cuda 6.5.

By the way this version allows control of voltage and OC of the cores as well as the manual fan control. Greetings.


NOTE:The voltage I still can not make it work ... we'll see.

Yes 341.05 will suffice. As stated by the webpage to which you link, the quadro 341.05 driver features CUDA 6.5. My Quadro K4000 is now getting tasks again after upgrading to 341.05.

Here v342.05 will only get CUDA 6.0 tasks due to application restrictions. You'll need v343.22 or above for CUDA 6.5 in Linux. For Windows v344.65 is the latest WHQL driver and it runs fine. Might as well use it.

Regarding the confusion about CUDA 6.5 in driver 340 / 341: are these the last drivers with legacy support for G80 etc.? This might explain why they might have gotten some bugfix after the release of the 343 branch.

From what I understand, the GPUs that recently were excluded from the latest GeForce driver sets... are still supported with R340 driver releases until April 2016.
http://nvidia.custhelp.com/app/answers/detail/a_id/3473

I even have an open NVIDIA Bug with them right now, where R340 (up to and including current 341.05 for my FX3800 M)... broke some of their OpenCL calculations that were working just fine in R337. They are supposedly working to fix it.

The drivers come from the same Release families (R337, R340, R343, etc.). And my point was, for the GPUs that have been deprecated from the R343 drivers.... The R340 drivers will have bugfix support for them until April 2016, for both Quadro and GeForce series of those R340 drivers.

341.05 is the latest R340 driver release for my Quadro FX3800 M, and as I said, I have an open bug with NVIDIA - they completely broke how the GPU calculates certain OpenCL functions, and they should hopefully have it fixed it in the upcoming R340 release. So far as I know, CUDA is calculating fine, but I have not personally tested it.

Jacob

I had trobule with the new driver. It locked the videos I tried to watch. I returned to the older drive and the problem ended, and this is because I still use an old driver.

I am not sure if will be able to use the newer driver. Has anyone had the same problem here? If so, how was it solved?

Hello: I see you have a very old GT 640 in Windows 7 and controller.

Unfortunately one GT 640 for GPUGRID is not appropriate, I do not accept assignments shortly. Greetings.

After 4.2 workunits were discontinued, it got one 6.0 workunit, which failed, and it now gets no GPU workunits from GPUGRID at all, only the CPU test workunits. What do I need to change in order the get GPU workunits again?

Hi Robert,

I tried to put together a comprehensive list of what is necessary to receive GPU workunits. You can either do step 1 and post back the results or take a look at your settings for steps 2-5 and see if anything needs to be changed.

- Happy crunching,
Steve

---------------------------------------------------------
1. Turn on the <work_fetch_debug> flag to see what BOINC
is doing during work fetch.
http://boinc.berkeley.edu/wiki/Client_configuration

-stop / restart boinc and post back with what the event
log says after it tries to get new work from GPUGrid.

- this will help identify if your issue is one of the
topics below or if we need to look deeper.
---------------------------------------------------------
2. Computing Preferences web
http://www.gpugrid.net/prefs.php?subset=global
Suspend GPU work while computer in use = no
- if yes then used in conjunction with ...
'In use' means mouse/keyboard activy in last "x" minutes
Suspend GPU work while computer in use = no
----------------------------------------------------------
3. Computing Preferences local (takes precendece over web)
Boinc Manager - Advanced View (ctrl+shift+a)
Tools menu --> Computing preferences
same as above but if you have set local preferences
then you will be always running local preferences and
nothing you chnage on the website for preferences will
matter until after you press the 'Clear' button. Keep in
mind this is "BOINC wide" setting so the last site you
chnaged this on across all of the projects you are
connected to takes precedence.
---------------------------------------------------------
4. Project preferences
http://www.gpugrid.net/prefs.php?subset=project
- Use NVIDIA GPU = on
- ACEMD short runs
----------------------------------------------------------
5. Activity Status
Boinc Manager - Advanced View (ctrl+shift+a)
Activity menu
- Suspend = off
- If 'Run based on preferences' = on then see Computing Preferences above
- Suspend GPU = off
- If 'Use GPU based on preferences' = on then see Computing Preferences above
---------------------------------------------------------

What do you mean by "locked the video"? The driver neither plays back videos, nor does it allow or forbid which ones to play. It does provide an interface for hardware acceleration of video playback, which other software can hook into. Maybe your video player (which one?) is too old for a modern nVidia driver? Update it or try VLC?

BTW: your GT640 is not powerful, but it can still rturn "long runs" within 2 days just fine, if you run 24/7. Otherwise it does can run "short runs" just fine. I would not recommend to buy one for GPU-Grid, but if you have you can still use it for some time :)

@Robert: I can not see any recent GPU task for your PC, only some very old errors and 2 CPU tasks.

I am running Nvidia driver 344.75 for my Titan Z, which is obviously not a 900 series gpu. I have noticed issues with WU's and it does not seem to be functioning as it was before with an older driver and my sli 780's. Any advice?

I'd try turning off the CPU and test apps and then see if the GPU apps will run. Right now they don't seem to be starting and just time out.

I tried uninstalling BOINC client and reinstalling, letting BOINC benchmark run, then running GPU Grid to no avail--I am getting about 70% through long-run WU's and then crash! Worst part is, I seem to be starting over on WU's when i reboot the system and not completing the WU's that were almost finished. This has to be a driver issue, because my sli 780's were running fine on 340.52 driver, and I did not update to driver 344.75 until I installed my Titan Z. I have not tried my Titan Z on 340.52 because I heard GPU Grid will not give me any WU's, but I know this new driver has to be the issue!

Will i get work units if I roll my 344.75 driver back to 340.52, the last known good working configuration I had? 340.52 driver is only 6-8 months old, but I cannot get 344.75 to run. As soon as i start boinc client, my driver crashes, restarts, then it will let me run wu's, but then the whole system crashes 3/4 of the way through long run wu's.

Are you doing any overclocking? Also, are you making sure to keep your GPU temps below 70*C? Does it error in Heaven 4.0 at maximum settings for 5 hours? Have you tried downclocking it until it stops erroring?

Well I see you have two PC's, but they are the same so could be the same one.
But if there are two then you can install an older driver on one PC and see what happens. If not working, update to the next driver and so on.

I have tried downclocking, default clocks and overclocking, same results. Temps never go above 65c with aggressive fan profile, cpu is overclocked to 4.715 Ghz, fx8350, but thats the same overclock i have always used for gpu grid, and previously with my sli 780's

I have not ran haven benchmark for 5 hours, but have run full benchmarks with no issues, as well as normal gameplay with no issues. The system does not become unstable until I start up BOINC client, as far as I can tell anyway

You can try other 344 dirvers:
344.11
344.48
344.60
344.65
Did you checked all power connectors in your PC (including the 24 pin MB power connector) for burn marks, or loose connections?
Do you use any power connector converters, or extension wires inside your PC?

EDIT: you can try uninstalling the GPU driver, then use driver sweeper to remove any remaining driver files before installing different drivers.

Suferbus,

if you run those 3D benchmarks, do they really tax all 4 GPUs? I'm not sure how to tell.. maybe setting Heaven to something as demanding as possible but in windowed mode to observe GPU-Z readings. Or if you have a power meter: what's the power consumption, running those benchmarks and GPU-Grid? What's your PSU? A power hungry CPU and 2 Titan Z (375W each) can be quite demanding. Significantly more so than 2 GTX780Ti with 250 W TDP.

Does it help if you use only 1 Titan Z? Just for a test, of course ;)
In this case I wouldn't blame the driver.

There is only 1 Titan Z present in that host, as dual GPU boards are always treated by BOINC like 2 GPUs. So if there were 2 Titan Z's in that host, the host's page should show "[4] NVIDIA GeForce GTX TITAN Z (4095MB) driver: 340.52".

Yes Zoltan. Although there were two computers, it's just one.
I'm just curious how many of one Titan z is able to be calculated rac for one day.
If everything works fine.. Because that man is here for the first with that monster GF card :-)
Suferbus has similar problems as when here came some new model gf card into the project. Also there fell nvidia driver and the task. Had nothing overclocked and the clean install os there .. Project scientists probably surely do not have a few Titans Z to test job before releasing tasks out.
If it works this way. I do not know. -))

Titan Z should use the same GK110 GPU as GTX780/Ti, Titan and Titan Black before it, so nothing should change software-wise. There's been a revision of that chip, but those normally don't change software-features.

Well, there's also been the release of GK210 for professional cards with minor feature changes. As far as I know Titan Z shouldn't use this one, and neither *should* it break compatibility. Actually it'S not, because the new chip reports compute capability of 3.7, which Suferbus' card does not.

Hi! I'm a fairly ignorant user of BOINC and so, I don't understand if this information affects me. I have an NVidia gtx 750 Ti SC graphics card, which, to my understanding, uses Maxwell architecture) and its drivers are always up to date. Are these the drivers you're referring to that should be updated? If not, please provide me with a fairly "for dummies" explanation of how to update said Cuda drivers.

Thank you very much! :)

It does not affect you.

I have an NVidia gtx 750 Ti SC graphics card, which, to my understanding, uses Maxwell architecture) and its drivers are always up to date.

The GTX750Ti haven't had drivers which could have been affected by the depreciation of CUDA 4.2.

Are these the drivers you're referring to that should be updated?

Yes, they are. But since you have the latest drivers, you have nothing to do right now.

If not, please provide me with a fairly "for dummies" explanation of how to update said Cuda drivers.

The CUDA drivers are included in the display drivers, so when you update your display driver next time, your CUDA driver also will be updated.
In some rare cases however, the Driver Sweeper could help to remove any remaining files from old drivers.

Thank you very much! :)

You're welcome.

My previous reply to this message has disappeared. However, only item 4 below gave unexpected results.


4. Project preferences
http://www.gpugrid.net/prefs.php?subset=project
- Use NVIDIA GPU = on
- ACEMD short runs


I'm now getting both long and short 6.47 GPU workunits on this computer. However, all of them have the workunit repeatedly going unstable, and then failing with an unknown error message. In case it matters, this computer runs 64-bit Windows Vista.

Your message did tell me what to look for in order to enable CPU workunits but not GPU workunits on my other computer, though. The GPU heatsink on it needs cleaning, but is unreachable.

Suferbus,

I've seen a somewhat similar problem on two computers. On one, the graphics board fan was no longer turning, so the GPU quickly overheated after each reboot.

On the other, the GPU heatsink needed cleaning to prevent the GPU from overheating, but the graphics board cover could not be removed to allow this cleaning.

If you use this (TThrottle) along with another of Fred's excellent programs (BoincTasks) you can monitor all of the computers on your network for CPU and GPU temps along with all of your BOINC activity.
