1.11.0
bdedc53

Thrust 1.11.0 is a major release providing bugfixes and performance enhancements. It includes a new sort algorithm that provides up to 2x more performance from thrust::sort when used with certain key types and hardware. The new thrust::shuffle algorithm has been tweaked to improve the randomness of the output. Our CMake package and build system continue to see improvements with better add_subdirectory support, installation rules, status messages, and other features that make Thrust easier to use from CMake projects. The release includes several other bugfixes and modernizations, and received updates from 12 contributors.

New Features

  • NVIDIA/cub#204: New implementation for thrust::sort on CUDA when using 32/64-bit numeric keys on Pascal and up (SM60+). This improved radix sort algorithm provides up to 2x more performance. Thanks for Andy Adinets for this contribution.
  • #1310, #1312: Various tuple-related APIs have been updated to use variadic templates. Thanks for Andrew Corrigan for these contributions.
  • #1297: Optionally add install rules when included with CMake's add_subdirectory. Thanks to Kai Germaschewski for this contribution.

Bug Fixes

  • #1309: Fix thrust::shuffle to produce better quality random distributions. Thanks to Rory Mitchell and Daniel Stokes for this contribution.
  • #1337: Fix compile-time regression in transform_inclusive_scan and transform_exclusive_scan.
  • #1306: Fix binary search middle calculation to avoid overflows. Thanks to Richard Barnes for this contribution.
  • #1314: Use size_t for the index type parameter in thrust::tuple_element. Thanks to Andrew Corrigan for this contribution.
  • #1329: Fix runtime error when copying an empty thrust::device_vector in MSVC Debug builds. Thanks to Ben Jude for this contribution.
  • #1323: Fix and add test for cmake package install rules. Thanks for Keith Kraus and Kai Germaschewski for testing and discussion.
  • #1338: Fix GCC version checks in thrust::detail::is_pod implementation. Thanks to Anatoliy Tomilov for this contribution.
  • #1289: Partial fixes for Clang 10 as host/c++ compiler. Exposed an nvcc bug that will be fixed in a future version of the CUDA Toolkit (NVBug 3136307).
  • #1272: Fix ambiguous iter_swap call when using thrust::partition with STL containers. Thanks to Isaac Deutsch for this contribution.
  • #1281: Update our bundled FindTBB.cmake module to support latest MSVC.
  • #1298: Use semantic versioning rules for our CMake package's compatibility checks. Thanks to Kai Germaschewski for this contribution.
  • #1300: Use FindPackageHandleStandardArgs to print standard status messages when our CMake package is found. Thanks to Kai Germaschewski for this contribution.
  • #1320: Use feature-testing instead of a language dialect check for thrust::remove_cvref. Thanks to Andrew Corrigan for this contribution.
  • #1319: Suppress GPU deprecation warnings.

Other Enhancements

  • NVIDIA/cub#213: Removed some tuning policies for unsupported hardware (<SM35).
  • References to the old Github repository and branch names were updated.
    • Github's thrust/cub repository is now NVIDIA/cub
    • Development has moved from the master branch to the main branch.
