CUDA Python 11.8.7

Release notes

• https://nvidia.github.io/cuda-python/12.9.0/release/11.8.7-notes.html

cuda.core v0.2.0

cuda.core v0.2.0 release announcement

Release note

• https://nvidia.github.io/cuda-python/cuda-core/latest/release/0.2.0-notes.html

All functionalities are currently hosted under the cuda.core.experimental namespace. Once the features become stable they will be moved out of experimental.

Key Features and Enhancements

• Add ProgramOptions to facilitate the passing of runtime compile options to Program.
• Add pythonic access to Device and Kernel attributes.

For full details please refer to the release note above.

Breaking Changes

• The stream attribute is removed from LaunchConfig. Instead, the Stream object should now be directly passed to launch as an argument.
• The signature for launch is changed by swapping positional arguments, the new signature is now (stream, config, kernel, *kernel_args)
• Change __cuda_stream__ from attribute to method.
• The Program.compile method no longer accepts the options argument. Instead, you can optionally pass an instance of ProgramOptions to the constructor of Program.
• Device.properties now provides attribute getters instead of a dictionary interface.
• The .handle attribute of various cuda.core objects now returns the underlying Python object instead of a (type-erased) Python integer.

New examples

• jit_lto_fractal.py — Demonstrates just-in-time link-time optimization for fractal generation. (Device, LaunchConfig, Linker, LinkerOptions, Program, ProgramOptions) (#475)
• simple_multi_gpu_example.py — Example of using multiple GPUs. (Device, Program, LaunchConfig) (#304)
• show_device_properties.py — Displays detailed device properties. (Device) (#474)
