v0.13.0

Added

• Implemented and deployed dedicated kernels for copying with casting #781, used in __setitem__, implementaion of asarray, dpctl.tensor.copy functions.
• Implemented dedicated copying kernel for dpctl.tensor.reshape function #810, added support for copy keyword #807.
• Implemented dedicated kernel to copy with casting from numpy.ndarray into dpctl.tensor.usm_ndarray #817.
• Implemented dpctl.tensor.permute_dims function from array-API #787.
• Implemented dpctl.tensor.expand_dims function from array-API #788.
• Implemented dpctl.tensor.squeeze function from array-API #790.
• Implemented dpctl.tensor.broadcast_to function from array-API #791.
• Implemented dpctl.tensor.broadcast_arrays function from array-API #798.
• Implemented dpctl.tensor.flip function from array-API #801.
• Implemented dpctl.tensor.usm_ndarray.mT property per array-API #805.
• Implemented dpctl.tensor.roll function from array-API #809.
• Implemented dpctl.tensor.arange function from array-API #814.
• Implemented dpctl.tensor.zeros function from array-API #816.
• Implemented dpctl.tensor.zeros function from array-API #816.
• Implemented dpctl.tensor.ones, dpctl.tensor.full, dpctl.tensor.empty_like, dpctl.tensor.zeros_like, dpctl.tensor.ones_like, dpctl.tensor.full_like functions from array-API #822.
• Implemented DPCTLQueue_Memset function in SyclInterface library #812, and exposed it for dpctl.memory.MemoryUSM* classes #815.
• Implemented dpctl.utils.get_coerced_usm_type to deduced usm type of the output array from types of input arrays in compute-follows-data execution model #797.
• Added dpctl.SyclDevice.profiling_timer_resolution property #825.
• Added dpctl.SyclDevice.platform and dpctl.SyclPlatform.default_context properties #827.
• Provided pybind11 example for functions working on dpctl.tensor.usm_ndarray container applying oneMKL functions #780, #793, #819. The example was expanded to demonstrate implementing iterative linear solvers (Chebyshev solver, and Conjugate-Gradient solver) by asynchronously submitting individual SYCL kernels from Python #821, #833, #838.
• Wrote manual page about working with dpctl.SyclQueue #829.
• Added cmake scripts to dpctl package layout and a way to query the location #853.
• Implemented dpctl.tensor.concat function from array-API #867.
• Implemented dpctl.tensor.stack function from array-API #872.

Changed

• Enhanced coverage collection for SyclInterface library by also collecting it during pytest run and combining traces with those collected during C-test run #818. This change also allows to not rebuild SyclInterface library when building C-test executable.
• Exported keep_args_alive utility in dpctl4pybind11.hpp header #820. The utility uses sycl::handler::host_task to keep given Python arguments alive until eac sycl::event from the given vector of events is complete. The host task is scheduled on the SYCL queue provided as the first argument.
• Changed the size of struct underlying dpctl.SyclEvent to avoid storing Python object previously used to keep kernel arguments scheduled with dpctl.SyclQueue.submit #823.
• Fixed docstring for dpctl.SyclTimer #824.
• Changed type of exceptions raised on failure to create dpctl.SyclDevice from ValueError to dpctl.SyclDeviceCreationError #826.
• Improved performance of pybind11 type casters #837.
• Changed implementation of dpctl.SyclProgram from using deprecated sycl::program to sycl::kernel_bundle #845.
• Removed deprecated device aspects, added new supported aspects #844.
• Updated vendored dlpack.h to version 0.7 #847.

Fixed

• Fixed dpctl.lsplatform() to work correctly when used from within Jupyter notebook #800.
• Fixed script to drive debug build #835 and fixed code to compile in debug mode #836.
• Fixed filter selector string produced in outputs of dpctl.lsplatform(verbosity=2) and dpctl.SyclDevice.print_device_info #866.
• Fixed issue with slicing reported in gh-870 in #871.
