Reference
CUDALink allows
Mathematica to use the CUDA parallel computing architecture on Graphical Processing Units (GPUs). It contains functions that use CUDA-enabled GPUs to boost performance in a number of areas, such as linear algebra, financial simulation, and image processing.
CUDALink also integrates CUDA with existing
Mathematica development tools, allowing a high degree of automation and control.
This section summarizes the functionality.

CUDALink Examples
Example applications of CUDALink.
CUDAQ and CUDAInformation
CUDAInformation gives user information on the hardware. To use, first load the
CUDALink application.
This gets information on the CUDA devices on the system.
| Out[2]= |  |
Similar to other
Mathematica 
functions,
CUDAQ will not return an error on failure. Running
CUDAInformation will give an error describing why CUDA failed.
If
CUDALink fails, it will return one of the following errors.
| insys | CUDALink is not supported on the system; only "Linux", "Linux-x86-64", "Windows", "Windows-x86-64", "MacOSX-x86", and "MacOSX-x86-64" are supported |
| invdevnm | based on the video card name, the video card is not supported by CUDALink |
| invdirv | an NVIDIA driver library was not found, and CUDALink was not able to determine the NVIDIA driver library path |
| invdrivp | an NVIDIA driver was not found in the NVIDIA library path |
| invdrivver | an NVIDIA driver was found, but the version information cannot be determined |
| invdrivverv | an NVIDIA driver was found, but the version is unsupported |
| invdrivverd | an NVIDIA driver was found, but the version directory cannot be determined |
| syslibfld | loading the CUDA runtime libraries failed |
| initlib | loading the CUDALink library failed |
| init | CUDALink libraries were loaded, but initialization failed |
| nodev | CUDALink was unable to find a device that is CUDA compatible |
CUDALink detection failure error codes.
There are three main reasons for getting
False from
CUDAQ:
- Unsupported operating system — CUDA is not supported on SUN's Solaris or versions of Apple's OS X earlier than 10.6.3.
- Unsupported hardware — CUDA only works on CUDA-capable graphics cards.
- Incompatible graphics driver — a recent NVIDIA driver is needed for CUDA to operate properly.
System Requirements
CUDALink requires a compatible operating system, hardware, and driver software. This section describes what these are and how to confirm them.
Operating System
CUDALink is supported on Linux, Linux-x86-64, Windows, Windows-x86-64, Mac OS X-x86, and Mac OS X-x86-64. Mac OS X users need at least Mac OS X 10.6.3.
On Linux,
CUDALink requires the system to be run in a runlevel that will load the video drivers. Usually this is default level 5, but on some servers the administrator may need to configure it manually.

An updated list of device support can be found on the
NVIDIA CUDA-Enabled Products page.
Users with ATI or Intel graphics processors will not be able to use CUDA, but might be able to use OpenCL using
OpenCLLink.
Double-Precision Support
CUDALink will use double precision if it is available on the hardware detected. The following hardware has double-precision support:
- NVIDIA Tesla Workstation: Tesla C2050/C2070 and Tesla C1060.
- NVIDIA Tesla Data Center: Tesla M2050/M2070, Tesla S2050, Tesla S1070, and Tesla M1060.
- NVIDIA Quadro: Quadro 6000, Quadro 5000, Quadro 4000, Quadro FX 5800, Quadro FX 4800, and Quadro FX 3800.

- GeForce: GeForce GTS 480, GeForce GTS 470, GeForce GTS 465, GeForce GTS 460, GeForce GTS 450, GeForce GTX 295, and GeForce GTX 285.
If double-precision support is not detected, then
CUDALink will represent floating-point numbers in single precision.
An updated list of computer capability can be found on the
NVIDIA CUDA-Enabled Products page.
Programmatically, you can detect whether the cards on the system support double precision using
CUDAInformation and checking if the
is greater than or equal to 1.3.

CUDAInformation.

Graphics Card Information
Detailed information on your graphics can be found in the
section of
SystemInformation, as shown below.
| Out[1]= |  |
This gives information on the graphics card installed on the system.
If you have trouble finding this, then checking the graphics card is done by either checking the system documentation or going to one of the following:
- Device Manager on Windows
- System Information on Mac OS X
Checking the NVIDIA Driver
CUDALink has a driver version detection mechanism that is accessible using
CUDADriverVersion.
| Out[1]= |  |
An alternative to this driver detection method is operating-system specific. The following details how to get the driver version on Windows, Linux, and Mac OS X.
Windows
If the NVIDIA driver is installed, then the NVIDIA control panel should be in the system's control panel and will give you information. The NVIDIA control panel can be accessed by clicking .
Inside the control panel you will see the NVIDIA control panel.
Clicking on that will open windows that allow you to edit the hardware setup.
Clicking in the bottom-left corner will give you the following window.
This tells you the driver version, which is 257.21 on this machine.
Linux
If the NVIDIA driver is installed, then running
from the command line will give version information. The following screen capture shows the system running the 256.53 version of the NVIDIA driver, which can be seen in the "NVIDIA Driver Version" system information.
If X is not available, then the following command will tell you the driver version installed.
[abduld@abduldlx ~]$ ls /usr/lib/libnvidia-tls.so.*
/usr/lib/libnvidia-tls.so.2 /usr/lib/libnvidia-tls.so.256.53.15
The above tells you a non-supported NVIDIA driver 256.53.15 is installed on
. Note that on some versions of Linux the drivers are installed in
or in another nondefault location.
Mac OS X
To find the version information on OS X, open the window and go into .
Opening will show a button if the CUDA driver is installed.
Clicking on the button will show both the CUDA driver and GPU driver versions.
CUDA driver version 3.1 or above is required by
CUDALink.
