0.5.1rc2

Added

• Documentation improvements
• Cmake improvements and Coverage for C API
• Add support for Level Zero
• Code of conduct

Fixed

• Remove cython from install_requires. It allows use dpCtl in numba extensions.
• Incorrect import in example.

0.5.1rc1

Added

• Documentation improvements

Fixed

• Remove cython from install_requires. It allows use dpCtl in numba extensions.

0.5.0

Added

• _Memory.get_pointer_type static method which returns kind of USM pointer.
• Utility functions to transform string to device type and back.
• New dpctl.dptensor.numpy_usm_shared module containing USM array. USM array
  extends NumPy ndarray.
• A lot of new examples. Including examples of building Cython extensions with DPC++ compiler that interoperate with dpCtl.
• Mechanism for registering a callback function to look and see if the object
  supports USM.

Changed

• setup.py builds C++ backend for develop and install commands.
• Building wheels.
• Use DPC++ runtime from package dpcpp_cpp_rt.
• All usage of DPPL in C-API functions was changed to DPCTL, e.g., DPPLQueueMgr_GetCurrentQueue to DPCTLQueueMgr_GetCurrentQueue.
• Renamed the C-API directory is now called dpctl-capi instead of backends.
• Refactoring the dpctl-capi functions to prepare for changes to add Level Zero program creation.
• SyclProgram and SyclKernel classes were moved out of dpctl into the dpctl.program sub-module.

Fixed

• Klockwork static code analysis warnings.

0.5.0rc4

• Updated documentation, CHANGELOG and README.
• Added one test.

3rd RC for 0.5.0

3rd integration release.

• Updated examples
• New way to check that objects support USM

Second RC candidate for 0.5.0

• Renaming ofdppl to dpctl is now completed.
• Examples added to the main repo
• SyclProgram, SyclKernel, and program creation functions moved out of dpctl into dpctl.program.

0.4.0: Improved USM memory manager

• New device info attributes are exposed using SyclDevice
  • max_compute_units
  • max_work_item_dimensions
  • max_work_item_sizes
  • max_work_group_size
  • max_num_sub_groups
  • aspects for int64 atomics
• Major changes and improvements to dpctl.memory
  • MemoryUSM* classes moved to dpctl.memory module,
  • added support for aligned allocation, added support for prefetch and mem_advise (sychronous) methods, implemented copy_to_host, copy_from_host and copy_from_device methods, pickling support, and zero-copy interoperability with Python objects which implement sycl_usm_array_inerface protocol.
• Helper scripts to generate API documentation for both C API and Python.
• Other improvements and bug fixes.

0.3.8: Final release for oneAPI Beta 10

• Fix failing platform test case. (#116)

• Change how the initial active queue is populated inside DPPLQueueMgr.

• It is fine for the queue manager to store the host queue. Up to clients what they want to do with it.

• Fix Gtests configuration.

• Properly skip tests when no OpenCL devices are available.

• Only report number of non-host platforms.

• Add skip tests to test_sycl_usm.py

• Raise exception if DPPLSyclQueueRef is NULL.

0.3.7: Only use the first device for each device type and backend

• Fixes a crash on Windows due a Level Zero driver problem. Each device was getting enumerated twice. To handle the issue, we added a temporary fix to use only first device for each device type and backend (#118).

0.3.6: Fix Windows Install

• Add change log
• Fix install on Windows
