Changelog
All notable changes to the hipFile Python bindings will be documented in this file.
[Unreleased]
[0.4.0.dev0]
Added
- Cython and Python API support for the hipFile async stream I/O APIs.
- High-level
FileHandle.read_async/FileHandle.write_asyncmethods for submitting asynchronous I/O on a stream. Streamcontext manager for registering and deregistering a HIP stream.AsyncIOHandleholding the async operation's I/O parameters and receiving the transferred byte count once the stream completes.supports_async()to report whether the loaded library implements the async API.
[0.3.0.dev0]
Added
- Docstrings for the public Python API.
[0.2.0.dev1]
Fixed
- Release the Python GIL during all C function calls to prevent blocking other threads during GPU IO operations. This resolves a performance regression observed in multi-threaded applications (e.g., LMCache) when switching from ctypes-based bindings to the Cython bindings.
Added
- Complete typing hints for the public API.
[0.2.0.dev0]
Added
- Initial release of the hipFile Python bindings.
- Cython-based low-level wrappers for the hipFile C API (
_hipfile.pyx). - High-level Pythonic API:
Driver,FileHandle,Bufferclasses with context manager support. hipMalloc/hipFreehelpers for GPU memory allocation.- Error handling via
HipFileExceptionwith hipFile and HIP driver error codes. FileHandleTypeandOpErrorenums.get_version()anddriver_get_properties()utility functions.- scikit-build-core based build system.
