Thrust 1.14.0 (NVIDIA HPC SDK 21.9)

Thrust 1.14.0 is a major release accompanying the NVIDIA HPC SDK 21.9.

This release adds the ability to wrap the thrust:: namespace in an external namespace, providing a workaround for a variety of shared library linking issues. Thrust also learned to detect when CUB's symbols are in a wrapped namespace and properly import them. To enable this feature, use #define THRUST_CUB_WRAPPED_NAMESPACE foo to wrap both Thrust and CUB in the foo:: namespace. See thrust/detail/config/namespace.h for details and more namespace options.

Several bugfixes are also included: The tuple_size and tuple_element helpers now support cv-qualified types.
scan_by_key uses less memory. thrust::iterator_traits is better integrated with std::iterator_traits. See below for more details and references.

New Features

• #1464: Add preprocessor hooks that allow thrust:: to be wrapped in an external namespace, and support cases when CUB is wrapped in an external namespace.

Bug Fixes

• #1457: Support cv-qualified types in thrust::tuple_size and thrust::tuple_element. Thanks to Jake Hemstad for this contribution.
• #1471: Fixed excessive memory allocation in scan_by_key. Thanks to Lilo Huang for this contribution.

• #1488: Fixed the path to the installed CUB headers in the CMake find_package configuration files.
• #1491: Fallback to std::iterator_traits when no thrust::iterator_traits specialization exists for an iterator type. Thanks to Divye Gala for this contribution.
