Changelog

All notable changes to this project will be documented in this file.

[Unreleased]

Added

  • setup.py builds C++ backend for develop and install commands.

[0.4.0] - 2020-11-04

Added

  • Device descriptors "max_compute_units", "max_work_item_dimensions", "max_work_item_sizes", "max_work_group_size", "max_num_sub_groups" and "aspects" for int64 atomics inside dpctl C API and inside the dpctl.SyclDevice class.
  • 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.

Fixed

  • Compiler warnings when building libDPPLSyclInterface and the Cython extensions.

Removed

  • The Legacy OpenCL interface.

[0.3.8] - 2020-10-08

Changed

  • How the initial active queue is populated inside DPPLQueueMgr.
  • dpctl.SyclQueueManager only reports the number of non-host platform.
  • dpctl.SyclQueueManager now raises an exception if DPCTL C API returns a nullptr instead of a valid Sycl queue.

Fixed

  • Several crashes in cases where an OpenCL or Level Zero platform is not available.
    • Fix failing platform test case. (#116)
    • Properly skip tests when no OpenCL devices are available.
    • Add skip tests to test_sycl_usm.py
    • Fix Gtests configuration.

[0.3.7] - 2020-10-08

Fixed

  • 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] - 2020-10-06

Added

  • Changelog was added for dpctl.

Fixed

  • Windows build was fixed.

[0.3.5] - 2020-10-06

Added

  • Add a helper function to all Python SyclXXX classes to get the address of the base C API pointer as a long.

Changed

  • Rename PyDPPL to dpCtl in comments (function name renaming to come later)

Fixed

  • Fix bugs highlighted by tools.
  • Various code clean ups.

[0.3.4] - 2020-10-05

Added

  • Dump functions were enhanced to print back-end information.
  • dpctl gained support for unint_8 and unsigned long data types.
  • oneAPI Beta 10 tool chain support was added.

Changed

  • dpctl is now aware of DPC++ Sycl PI back-ends. The functionality is now exposed via the context interface.
  • C API's queue manager was refactored to require back-end.
  • dpct's device_context now requires back-end, device-type, and device-id to be provided in a string format, e.g. opencl:gpu:0.

Fixed

  • Fixed some important bugs found by static analysis.

[0.3.3] - 2020-10-02

Added

  • Add dpctl.get_curent_device_type().

[0.3.2] - 2020-09-29

Changed

  • Set _cpu_device and _gpu_device to None by default.

[0.3.1] - 2020-09-28

Added

  • Add get include and include headers.

Changed

  • DPPL shared objects are installed into dpctl.

Fixed

  • Refactor unit tests.

[0.3.0] - 2020-09-23

Added

  • Adds C and Cython API for portions of Sycl queue, device, context interfaces.
  • Implementing USM memory management.

Changed

  • Refactored API to expose a minimal sycl::queue interface.
  • Modify cpu_queues, gpu_queues and active_queues to functions.
  • Change static vectors to static pointers to verctors. It disables call for destructors. Destructors are also call in undefined order.
  • Rename package PyDPPL to dpCtl.
  • Use dpcpp.exe on Windows instead of dpcpp-cl.exe deleted in oneAPI beta08.

Fixed

  • Correct use ERRORLEVEL in conda scripts for Windows.
  • Fix using dppl.has_sycl_platforms() and dppl.has_gpu_queues() functions in skipIf
