GPU processing during the modeling and settings

[Lambo]

I just had the same problem were the Dense Cloud generation was taking too long and when I checked, VOILA the GPU was not being used. So as you guys suggested, I rolled back to an earlier version of the driver and now it works fine :0
Thanks all for the info!

I'm having the same problem. Using GeForce GTX 580. Which old driver should I use? How far back should I go?

Thanks.

I went back to driver  "GeForce 332.21 Driver WHQL     January 7, 2014 "  on the NVidia drivers download page and it works fine.
I think that the bad one is the 340.52 so anything older than that should be fine.

Hi, I've just started using Photoscan, so please bear with me.

When Im trying to build dence point cloud, I can see in the console that it says:

oc1_engine.cpp line231: clEnqueueWriteBuffer failed, CL_MEM-OBJECT_ALLOCATION_FAILURE
GPU processing failed, switching to CPU mode

My initial thoughts goes to Driver issue.

Is there anyone here who can recommend a Nvidia driver that works well with Photoscan?

I have Nvidia GTX770 2GB,


Best Regards

Hello Marius,

I've merged your topic with this one, as it is connected to the latest post.

Actually, the latest Nvidia drivers 340.52 causes the mentioned OpenCL processing problem, so we recommend to rollback to the previous version of drivers, while we are trying to find out if it could be fixed on our side.

Thanks Alexey.

Could it be a possibility to have a pinned post where the new drivers are verified as working or not working?

Hello everybody,
I’ve got a problem, I’ve changed GC, I installed a GTX 770 4gb, yesterday I tried it with a dset, but I got this message:
CL_MEM_OBJECT_ALLOCATON_FAILURE
Gpu processing failed, switching to cpu mode
So the soft wasn’t able to use GPU?
Any suggestion?, I think I’ve made a configuration mistake while installing the gpu…

Thanks,

Diego.

Hello Diego,

Please roll back from 340.52 nVidia drivers to the previous version.

Hello pjenness,

Could you please try installing PhotoScan 1.1.0 pre-release (http://www.agisoft.com/forum/index.php?topic=2883.0) and run a short test to check if the problem is solved?

Success thankyou!!

And this is with a 980GTX installed, with a 970GTX in a viDock eGPU solution as a secondary GPU card. (as I share it between desktop and mobile macBook)

Running test scene to benchmark now

Cheers!!
