rocThrust 3.2.0 for ROCm 6.3.1

rocThrust code for ROCm 6.3.1 did not change. The library was rebuilt for the updated ROCm 6.3.1 stack.

rocThrust 3.2.0 for ROCm 6.3.0

Added

• Merged changes from upstream CCCL/thrust 2.3.2
  • Only the NVIDIA backend uses tuple and pair types from libcu++, other backends continue to
    use the original Thrust implementations and hence do not require libcu++ (CCCL) as a dependency.
• Added the thrust::hip::par_det execution policy to enable bitwise reproducibility on algorithms that are not bitwise reproducible by default.

Changed

• Updated the default value for the -a argument from rmake.py to gfx906:xnack-,gfx1030,gfx1100,gfx1101,gfx1102,gfx1151,gfx1200,gfx1201.
• Enabled the upstream (thrust) test suite for execution by default. It can still be disabled by CMake option -DENABLE_UPSTREAM_TESTS=OFF.

Resolved issues

• Fixed an issue in rmake.py where the list storing cmake options would contain individual characters instead of a full string of options.
• Fixed the HIP backend not passing TestCopyIfNonTrivial from the upstream (thrust) test suite.
• Fixed tests failing when compiled with -D_GLIBCXX_ASSERTIONS=ON.

rocThrust 3.1.0 for ROCm 6.2.2

rocThrust code for ROCm 6.2.2 did not change. The library was rebuilt for the updated ROCm 6.2.2 stack.

rocThrust 3.1.0 for ROCm 6.2.1

rocThrust code for ROCm 6.2.1 did not change. The library was rebuilt for the updated ROCm 6.2.1 stack.

rocThrust 3.1.0 for ROCm 6.2.0

Additions

• Merged changes from upstream CCCL/thrust 2.2.0
  • Updated the contents of system/hip and test with the upstream changes to system/cuda and testing

Changes

• Updated internal calls to rocprim::detail::invoke_result to use the public API rocprim::invoke_result.
• Use rocprim::device_adjacent_difference for adjacent_difference API call.
• Updated internal use of custom iterator in thrust::detail::unique_by_key to use rocPRIM's rocprim::unique_by_key.
• Updated adjecent_difference to make use of rocprim:adjecent_difference when iterators are comparable and not equal otherwise use rocprim:adjacent_difference_inplace.

Known issues

• thrust::reduce_by_key outputs are not bit-wise reproducible, as run-to-run results for pseudo-associative reduction operators (e.g. floating-point arithmetic operators) are not deterministic on the same device.
• Note that currently, rocThrust memory allocation is performed in such a way that most algorithmic API functions cannot be called from within hipGraphs.
