) * Improve binary function objects and replace thrust implementation * simplify use of ::cuda::std binary_function_objects * Replace _CCCL_CONSTEXPR_CXX14 with constexpr in all libcudacxx binary function objects that are imported in thrust. * Determine partial sum type without ::result_type * Ignore _LIBCUDACXX_DEPRECATED_IN_CXX11 for doxygen Co-authored-by: Bernhard Manfred Gruber <[email protected]>
* Add script to update RAPIDS version. * Update to 24.10.
* fix broken links * revert repo.toml * linkchecker fixes * fix .cuh errors * lint
* Add a header to interact with driver APIs * Add a test for the driver API interaction * Format * Fix formatting
* Use `common_type` for complex `pow` Previously we would rely on our internal `__promote` function. However, that could have surprising results, e.g. `pow(complexy<float>, int)` would return `complex<double>` With C++23, this situation got clarified and we should use `common_type` to determine the return type.
… cache properties (#2110)
* Drop `cuda::get_property` CPO It serves no purpose as it only ever forwards via ADL and also breaks older nvcc * Ensure that we test memory resources * Implement `cuda::uninitialized_buffer` `cuda::uninitialized_buffer` provides an allocation of `N` elements of type `T` utilitzing a `cuda::mr::resource` to allocate the storage. `cuda::uninitialized_buffer` takes care of alignment and deallocation of the storage. The user is required to ensure that the lifetime of the memory resource exceeds the lifetime of the buffer.
…ice (#2073) * Ensure that `cuda_memory_resource` allocates memory on the proper device * Move `__ensure_current_device` to own header
* Clarify compatibility wrt. template specializations We do not want users to specialize arbitrary templates in CCCL unless otherwise stated. This PR makes this clear in the README.md. Co-authored-by: Michael Schellenberger Costa <[email protected]>
* Make `cuda::std::tuple` trivially copyable This is similar to the situation with `cuda::std::pair` We have a lot of users that rely on types being trivially copyable, so that they can utilize memcpy and friends. Previously, `cuda::std::tuple` did not satisfy this because it needs to handle reference types. Given that we already specialize `__tuple_leaf` depending on whether the class is empty or not, we can simply add a third specialization that handles the trivially copyable types and one that synthesizes assignment.

… it in places where it was missing (#2192) * Change __scoped_device to use driver API * Switch to use driver API based dev setter * Remove constexpr from operator device() * Fix comments and includes * Fallback to non-versioned get entry point pre 12.5 We need to use versioned version to get correct cuStreamGetCtx. There is v2 version of it in 12.5, fortunatelly the versioned get entry point is available there too * Fix unused local variable * Fix warnings in ensure_current_device test * Move ensure current device out of detail * Add LIBCUDACXX_ENABLE_EXCEPTIONS to tests cmake

Fixes #653. Adds three new workflows that can be manually triggered at various points in the release process: - `release-create-new`: Begin the release process for a new version. - Inputs: - `new_version`: The new version, eg. "2.3.1" - `branch_point`: Optional; If the `branch/{major}.{minor}.x` branch does not exist, create it from this SHA. If the release branch already exists, this is ignored. If not provided, the release branch is created from the current `main` branch. - Actions: - Creates release branch if needed. - Bumps version numbers with `update-version.sh` in topic branch. - Creates pull request to merge the topic branch into `main` - Marks the pull request for backporting to the release branch. - `release-update-rc`: Validate and tag a new release candidate. - Inputs: - `new_version`: The new version, eg. "2.3.1" - Actions: - Uses the HEAD SHA of the release branch for testing/tagging. - Determines the next rc for this version by inspecting existing tags. - Runs the `pull_request` workflow to validate the release candidate. This can be modified in the future to run a special rc acceptance workflow. - Tags the release candidate if the workflow passes. - `release-finalize`: Tag a final release. - Inputs: - `new_version`: The new version, eg. "2.3.1" - Actions: - Determines the most recent release candidate. - Tags the latest release candidate as the final release. [skip-matrix][skip-rapids][skip-vdc][skip-docs]

The `cccl_generate_install_rules` requires two arguments. When `CCCL_TOPLEVEL_PROJECT` doesn't exist all the existing calls will have `HEADERS_INCLUDE` or `NO_HEADERS` become the second argument.

Its a pain to retrieve the address of a device symbol.
This adds a little helper that makes it less painfull
