GridTools version 2.3.2

Bug fixes

• Apply workaround to CUDA 12.3, see #1766 (#1768)

GridTools version 2.3.1

Python bindings

• Python SID adapter: Add support for HIP/ROCm buffers (#1759)
• Python bindings: Nanobind SID adapter (#1762)

Bug fixes

• Partial workarounds for CUDA 12.1 and 12.2, see #1766 (#1764)
• Fix GCC 13: add missing include (#1761)

GridTools version 2.3.0

Support for NVHPC (#1747)

GridTools now supports NVHPC starting from release 23.3!

Parallel fn::backend::naive (#1746)

Naive (just parallel for, no blocking and other optimizations) OpenMP parallelization of the naive backend.

SID util to transform a dimension to a tuple_like element type (#1750)

Translates a SID with dimension D and element type T to a SID with D removed and type is tuple<T>-like, with tuple_size N for sid::dimension_to_tuple_like<D, N>(sid).

Bug fixes and smaller features

• fn: allow execution of stencils with 0d domain (#1728)
• Make pybind11::buffer sid copyable (#1755)

Build fixes

• Support for Clang 16 (#1751)

and other changes already included in v2.2.3

fn: SID neighbor table wrapper (#1730)

Adds a simple class that wraps a SID and implements the neighbour table concept. (Picked for convenience into 2.2.2.)

Support for Python packaging (#1720)

Starting with this release we will publish GridTools C++ on pypi.org to make it easier to consume GridTools C++ from GT4Py.

Bug fixes

• Fix CUDA 12.0 compilation (#1741)
• Improvements to Python packaging (#1742, #1743, #1744)
• Fix get_keys of empty hymap (#1728)
• fn: CUDA early exit on empty grid - an empty domain skips execution instead of erroring (#1729)
• fn: prefer qualified names over ADL for fn builtins (they are not customization points for the user) (#1731, #1732)
• Enable workarounds for CUDA 11.8 (#1734)
• Enable workarounds for Clang 15 (#1735)
• Update pybind11 version to fix wrong C++ standard (#1723)
• Fix perfect forwarding in sid::composite::make_values (#1722)
• Workaround for NVCC bug in gcl (present in 11.6, 11.7 and most likely in 11.8) (#1726)

Performance fixes

• Alternative skip value check in fn, which improves CUDA performance (#1721)

Build fixes

• Fix perftests CMake target when no tests are added (#1724)

Cleanup

• Replace boost::variant by std::variant (#1718)
