Compute capability

R2026b

CUDA compute capability for code generation

Model Configuration Pane: Code Generation / GPU Code

Description

The Compute capability parameter specifies the minimum compute capability for which GPU Coder™ generates CUDA^® code.

CUDA GPU compute capability is a numeric representation of the hardware features and instruction sets available for a GPU architecture. Selecting a higher compute capability enables new CUDA features, but you cannot run the compiled code on a GPU whose compute capability is less than the value of the Compute capability parameter. For code generation, different targets such as CUDA MEX functions or standalone executables have different compute capability requirements.

This table lists the CUDA compute capability requirements for code generation.

Target	Compute Capability
CUDA MEX	See GPU Computing Requirements.
Source code, static or dynamic library, and executables	3.2 or higher.
Deep learning applications in 8-bit integer precision	6.1, 7.0 or higher.
Deep learning applications in half-precision (16-bit floating point)	5.3, 6.0, 6.2 or higher.

Note

If you specify the Custom compute capability parameter, GPU Coder ignores this setting and uses the custom compute capability.

Dependencies

This parameter requires a GPU Coder license.
To enable this parameter, select the Generate GPU code (Simulink Coder) parameter.

Version History

Introduced in R2020b

expand all

R2026b: Target compute capabilities up to 12.1

You can now specify Compute capability as 10.0, 10.3. 11.0, 12.0, or 12.1. Previously, the highest value that you could set was 9.0.

R2026b: Default value changed

The default value of the Compute capability parameter is 7.5. Previously, the default value was 5.0.

When you open a model from a previous release that has a Compute capability value of 5.0, Simulink automatically updates the value to 7.5.
