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.

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:

23/11/2014 07:34:14 | | CUDA: NVIDIA GPU 0: GeForce GT 640 (driver version 314.07, CUDA version 5.0, compute capability 3.0, 2048MB, 1966MB available, 692 GFLOPS peak)

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.

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

Will Quadro driver v341.05 be enough with CUDA drivers?

EDIT: for Quadro tesla, all v340+ drivers should work! Just downloaded new tasks... ;)

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.
