Minimum compute capability

R2026b

Minimum CUDA compute capability for code generation

Description

App Configuration Pane: GPU Code

Configuration Objects: coder.GpuCodeConfig

The Minimum 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 Minimum 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.

Settings

Auto

This setting is the default setting.

Uses the compute capability of the GPU device that you select for GPU code generation. If no GPU device is available, the code generator uses a compute capability value of 7.5.

3.2 | 3.5 | 3.7 | 5.0 | 5.2 | 5.3 | 6.0 | 6.1 | 6.2 | 7.0 | 7.2 | 7.5 | 8.0 | 8.6 | 8.7 | 8.9 | 9.0 | 10.0 | 10.3 | 11.0 | 12.0 | 12.1

Builds generated code for the specified GPU compute capability.

Programmatic Use

Property: ComputeCapability

Values: "Auto" | "3.2" | "3.5" | "3.7" | "5.0" | "5.2" | "5.3" | "6.0" | "6.1" | "6.2" | "7.0" | "7.2" | "7.5" | "8.0" | "8.6" | "8.7" | "8.9" | "9.0" | "10.0" | "10.3" | "11.0" | "12.0" | "12.1"

Default: "Auto"

Version History

Introduced in R2018a

R2026b: Target compute capabilities up to 12.1

You can now specify Minimum 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 fallback value changed

When the Minimum compute capability parameter is set to Auto and MATLAB^® does not detect a compatible GPU device, the code generator uses a compute capability value of 7.5. In previous releases, if MATLAB did not detect a compatible GPU, the code generator used a compute capability 5.0.
