cuda installed but application not recognising it

Question

I have a MacPro 3,1 with a NVIDIA GeForce GTX 560 2Gb graphic card. I&#x27;ve installed the Cuda driver and the necessary command line tools according to these instructions.I have run the tests to see if installation was complete and got positive results. (See below.) When I open sorenson Squeezepro (9.0.3.11) and check the GPU preference panel I&#x27;m told Cuda drive is not installed on this computer.  Can anyone tell me if there is a sure fire way to check that Cuda is properly installed? If it is installed properly, why won&#x27;t Squeeze recognise it/Cheers and thanks for your help.Test resultsMacPro:release macpro$ ./deviceQuery./deviceQuery Starting...CUDA Device Query (Runtime API) version (CUDART static linking)Detected 1 CUDA Capable device(s)Device 0: "GeForce GTX 560"  CUDA Driver Version / Runtime Version          6.5 / 6.5  CUDA Capability Major/Minor version number:    2.1  Total amount of global memory:                 2048 MBytes (2147155968 bytes)  ( 7) Multiprocessors, ( 48) CUDA Cores/MP:     336 CUDA Cores  GPU Clock rate:                                1700 MHz (1.70 GHz)  Memory Clock rate:                             2004 Mhz  Memory Bus Width:                              256-bit  L2 Cache Size:                                 524288 bytes  Maximum Texture Dimension Size (x,y,z)         1D&#x3D;(65536), 2D&#x3D;(65536, 65535), 3D&#x3D;(2048, 2048, 2048)  Maximum Layered 1D Texture Size, (num) layers  1D&#x3D;(16384), 2048 layers  Maximum Layered 2D Texture Size, (num) layers  2D&#x3D;(16384, 16384), 2048 layers  Total amount of constant memory:               65536 bytes  Total amount of shared memory per block:       49152 bytes  Total number of registers available per block: 32768  Warp size:                                     32  Maximum number of threads per multiprocessor:  1536  Maximum number of threads per block:           1024  Max dimension size of a thread block (x,y,z): (1024, 1024, 64)  Max dimension size of a grid size    (x,y,z): (65535, 65535, 65535)  Maximum memory pitch:                          2147483647 bytes  Texture alignment:                             512 bytes  Concurrent copy and kernel execution:          Yes with 1 copy engine(s)  Run time limit on kernels:                     Yes  Integrated GPU sharing Host Memory:            No  Support host page-locked memory mapping:       Yes  Alignment requirement for Surfaces:            Yes  Device has ECC support:                        Disabled  Device supports Unified Addressing (UVA):      Yes  Device PCI Bus ID / PCI location ID:           2 / 0  Compute Mode:     &lt; Default (multiple host threads can use ::cudaSetDevice() with device simultaneously) &gt;deviceQuery, CUDA Driver &#x3D; CUDART, CUDA Driver Version &#x3D; 6.5, CUDA Runtime Version &#x3D; 6.5, NumDevs &#x3D; 1, Device0 &#x3D; GeForce GTX 560Result &#x3D; PASSMacPro:release macpro$ ./bandwidthTest[CUDA Bandwidth Test] - Starting...Running on...Device 0: GeForce GTX 560Quick ModeHost to Device Bandwidth, 1 Device(s)PINNED Memory Transfers   Transfer Size (Bytes) Bandwidth(MB/s)   33554432 3032.9Device to Host Bandwidth, 1 Device(s)PINNED Memory Transfers   Transfer Size (Bytes) Bandwidth(MB/s)   33554432 3267.9Device to Device Bandwidth, 1 Device(s)PINNED Memory Transfers   Transfer Size (Bytes) Bandwidth(MB/s)   33554432 101365.6Result &#x3D; PASSMacPro:release macpro$

I&#x27;ll try to help you, Lars. H. According to sorenson, your card does support CUDAhere are the drivers for snow Leopardhttp://www.nvidia.com/object/MacOSX-CUDA-3.0.htmlhere are minimum requirements for cuda in Sorenson Squeezenvida CUDA driver 3.1 or better, GPU driver 19.5.9f02, whatever that means, 512 meg of video memoryand here you will find latest  CUDAdrivers for your nVidia cardhttp://www.nvidia.com/object/mac-driver-archive.htmlsee if that helps you out. CUDA 6.5.18 adds support for 10.9.5. You&#x27;re supposed to be also able to download it by going to system prefences, then "other" , then CUDA, but I don&#x27;t have that installed on my Pro, so I can&#x27;t help you much more than this .John Bsorry-quick note here. If you go into Sorenson Squeeze, then Menu, then Preferences, then go to the GPU tab. your card should be recognized after you update the CUDA, then go to the GPU tab. Also, 10.9.5 may require that video memory for itself, leaving nothing for Sorenson Squeeze. You may have to buy a better video card, maybewhew ! hopefully this fixes it for now

Thanks JohnB, Cuda is installed (see the system report at the bottom of my first post) and I have the latest drivers.  I had it working before but I needed to do a complete system reinstall and can&#x27;t replicate what I did before to make Squeeze recognise my card. It used to be with Adobe that I had to go in to an invisible file and enter the card name so that the Adobe programs would look for and recognise my card (the GeForce GTX 560 was not one of the officially recognised cards at the time but by putting the card name in the list of cards Adobe looked for on start up this was fixed).  I wonder if this is the same with Squeeze. Ie, if there isn&#x27;t a file  that squeeze refers to with a list of &#x27;officially&#x27; recognised GPUs and its just a question of updating the list. BTW Adobe CC2014 sees my card and gives me the options of Cuda processing, OpenGL or just vanilla.

Yes, I think you&#x27;re on to something good there, Lars. Hope your terminal skills are good. I found something about "hacking" Premiere and CS6 to recognize your video card, as they recognize 4 cards. here&#x27;s a link to the hack in a video. Please note-I am no expert, and know nothing about Adobe stuff (mostly) or anything from Sorenson.  Hopefully this will give you an idea and get you startedhttp://www.vidmuze.com/videos/enable-gpu-cuda-in-adobe-cs6-for-mac/JB

Thanks again. Adobe seems to have fixed the issue with CC because I no longer need to edit the supported card list like in CS6.  I&#x27;ve been digging away at Squeezes and Adobes application content files and have found that both refer to CFBundle.....xml files. I&#x27;ve been looking at these files with text edit to see if any of them have a list of gpus but have come up with nothing so far. I figure there must be some system document or file that is referred to by the programs that tell them that there is a GPU installed and that it has CUDA, but where that file is is a mystery.
