Change Log for rocThrust

Full documentation for rocThrust is available at https://rocthrust.readthedocs.io/en/latest/

(Unreleased) rocThrust 2.13.0 for ROCm 5.0

Added

  • Updated to match upstream Thrust 1.13.0
  • Updated to match upstream Thrust 1.14.0
  • Added async scan

(Unreleased) rocThrust-2.11.2 for ROCm 4.5.0

Added

  • Initial HIP on Windows support. See README for instructions on how to build and install.

Changed

  • Packaging changed to a development package (called rocthrust-dev for .deb packages, and rocthrust-devel for .rpm packages). As rocThrust is a header-only library, there is no runtime package. To aid in the transition, the development package sets the "provides" field to provide the package rocthrust, so that existing packages depending on rocthrust can continue to work. This provides feature is introduced as a deprecated feature and will be removed in a future ROCm release.

Known issues

  • async_copy, partition, and stable_sort_by_key unit tests are failing on HIP on Windows.
  • Mixed type exclusive scan algorithm still not using the initial value type for results type.

[Unreleased rocThrust-2.11.1 for ROCm 4.4.0]

Added

  • gfx1030 support
  • Address Sanitizer build option

Fixed

  • async_transform unit test failure fixed.

[Unreleased rocThrust-2.11.0 for ROCm 4.3.0]

Added

  • Updated to match upstream Thrust 1.11
  • gfx90a support added
  • gfx803 support re-enabled

[rocThrust-2.10.9 for ROCm 4.2.0]

Added

  • Updated to match upstream Thrust 1.10

Changed

  • Minimum cmake version required for building rocThrust is now 3.10.2

Fixed

  • Size zero inputs are now properly handled with newer ROCm builds that no longer allow zero-size kernel grid/block dimensions
  • Warning of unused results fixed.

[rocThrust-2.10.8 for ROCm 4.1.0]

Added

  • No new features

[rocThrust-2.10.7 for ROCm 4.0.0]

Added

  • Updated to upstream Thrust 1.10.0
  • Implemented runtime error for unsupported algorithms and disabled respective tests.
  • Updated CMake to use downloaded rocPRIM.

[rocThrust-2.10.6 for ROCm 3.10]

Added

  • Added copy_if on device test case

Known issues

  • ROCm support for device malloc has been disabled. As a result, rocThrust functionality dependent on device malloc does not work. Please avoid using device launched thrust::sort and thrust::sort_by_key. Host launched functionality is not impacted. A partial enablement of device malloc is possible by setting HIP_ENABLE_DEVICE_MALLOC to 1. Thrust::sort and thrust::sort_by_key may work on certain input sizes but is not recommended for production code.

[rocThrust-2.10.5 for ROCm 3.9.0]

Added

  • Updated to upstream Thrust 1.9.8
  • New test cases for device-side algorithms

Fixes

  • Bugfix for binary search
  • Implemented workarounds for hipStreamDefault hang

[rocThrust-2.10.3 for ROCm 3.7.0]

Added

  • Updated to upstream Thrust 1.9.4

Changed

  • Package dependecy change to rocprim only

Known issues

  • ROCm support for device malloc has been disabled. As a result, rocThrust functionality dependent on device malloc does not work.

[rocThrust-2.10.1 for ROCm 3.5.0]

Added

  • Improved tests with fixed and random seeds for test data

Changed

  • CMake searches for rocThrust locally first; downloads from github if local search fails

Deprecated

  • HCC build deprecated
