Generate GPU code

R2026b

Enable code generation for GPUs

Model Configuration Pane: Code Generation

Description

The Generate GPU code parameter specifies whether to use GPU Coder™ and generate CUDA^® code.

Dependencies

• This parameter requires a GPU Coder license.

• To enable this parameter, select C++ for the Language and grt.tlc or ert.tlc for System target file.

• Enabling Generate GPU code selects Support long long and Support long long parameters on the Hardware Implementation pane.

• For an GRT-based system target file, enabling Generate GPU code changes the following parameters on the Code Generation > Optimization pane:

  • Selects None for Leverage target hardware instruction set extensions.

  • Enables Use memset to initialize floats and doubles to 0.0.

• For an ERT-based system target file, enabling Generate GPU code changes the following parameters on the Code Generation > Optimization pane:

  • Disables Generate parallel for-loops (Embedded Coder).

  • Selects <empty> for Disable incompatible optimizations.

• For an ERT-based system target file, enabling Generate GPU code selects Terminate function required (Embedded Coder) parameter on the Code Generation > Interface pane.
