Model Configuration Parameters: GPU Code

The Code Generation > GPU Code category includes parameters for configuring GPU-specific settings of the generated code.

These parameters require a GPU Coder™ license.

On the Configuration Parameters dialog box, the following configuration parameters are on the Code Generation > GPU Code pane.


Kernel name prefix

Specify custom kernel name prefixes.

GPU device index

Specify the CUDA® device to target.

Memory allocation mode

Specify the Memory allocation (malloc) mode to be used in the generated CUDA code.

Dynamic memory allocation threshold

Specify the size above which the private variables are allocated on the heap instead of the stack.

Stack size per GPU thread

Specify the maximum stack limit per GPU thread.


Replacement of math function calls with NVIDIA® cuBLAS library calls.


Replacement of math function calls with NVIDIA cuSOLVER library calls.


Replacement of math function calls with NVIDIA cuFFT library calls.

Include error checks in generated code

Add run-time error-checking functionality to the generated CUDA code.

Compute capability

Specify the minimum compute capability for which CUDA code is generated.

Custom compute capability

Specify the name of the NVIDIA virtual GPU architecture for code generation.

Additional compiler flags

Specify additional flags to the nvcc compiler.
