CUDA Samples v13.3

CUDA 13.3

• Added CUDA Tile C++ samples
• Added CCCL 3.3 feature samples
• Additional CUDA Python 1.0 samples

CUDA Samples v13.2 update

CUDA 13.2 samples update

• Added Python samples for CUDA Python 1.0 release
• Renamed top-level Samples directory to cpp to accommodate Python samples.

CUDA Samples v13.2

CUDA 13.2

• Added the MSVC compile flag -Xcompiler=/Zc:preprocessor in CMakeLists.txt to comply with CUDA13.2 CCCL. Previously, using the traditional preprocessor triggered the warning “MSVC/cl.exe with traditional preprocessor is used…”, which now leads to a build error.
• Minor bug fixes

CUDA Samples v13.1

Updates and bug fixes for the CUDA Toolkit v13.1 release.

CUDA Samples v13.0

CUDA 13.0

• Updated the samples using the cudaDeviceProp fields which are deprecated and removed in CUDA 13.0, replacing the fields with the equivalents in "cudaDeviceGetAttribute":
  • Deprecated "cudaDeviceProp" fields
    int clockRate; // - Replaced with "cudaDevAttrClockRate"
int deviceOverlap; // - Replaced with "cudaDevAttrGpuOverlap */
int kernelExecTimeoutEnabled; // - Replaced with "cudaDevAttrKernelExecTimeout
int computeMode; // - Replaced with "cudaDevAttrComputeMode" */
int memoryClockRate; // - Replaced with "cudaDevAttrMemoryClockRate"
int cooperativeMultiDeviceLaunch; // - Deprecated, cudaLaunchCooperativeKernelMultiDevice is deprecated.
