* VS: Avoid unnecessary CUDA device linking for OBJECT librariesRobert Maynard2023-09-112-0/+2
| | | | | | | Without `CudaLink` fields, MSBuild tries to perform a device link step for object libraries with CUDA_SEPARABLE_COMPILATION on them even when not needed. This commonly was encountered when generating PTX or OPTIX-IR output.

| | | | | | Found when developing https://github.com/conda-forge/cuda-nvcc-feedstock/pull/13/ We previously added RPATH entries for all implicit directories and therefore started to load the incorrect pthread library.

| | | | | | Since commit fa45594407 (file(GET_RUNTIME_DEPENDENCIES): Preserve casing for Windows PE binaries, 2023-03-06) we may find the cudart runtime library with its on-disk casing instead of always lower-case.

| | | | | | | Since commit 2def6a874b (CUDA: Add support for CUBIN, FATBIN, and OPTIXIR compilation, 2023-01-27) added this test, it has failed when executed with a CUDA toolkit that does not support the true native architecture of the GPU. Detect this case and skip the test.

* | CUDA: Add support for CUDA_ARCHITECTURES=nativeBrad King2022-03-101-1/+12
| | | | | | | | | | | | | | | | | | | | | | CUDA 11.6 added the `nvcc -arch=native` flag to automatically compile for the host GPUs' architectures. Add support for specifying this special `native` value in `CMAKE_CUDA_ARCHITECTURES` and `CUDA_ARCHITECTURES`. During the compiler ABI detection step, detect the native architectures so we can pass them explicitly when using Clang or older versions of nvcc. Fixes: #22375
* | Tests: Rename CudaOnly.{All => ArchSpecial}Brad King2022-03-103-4/+4
|/ | | | | | | | | The purpose of the test is to cover special values of `CMAKE_CUDA_ARCHITECTURES`. Prepare to add more than just `all` and `all-major`. While at it, fix the `project()` name in the test to match what we pass to `ctest` with `--build-project`.
* Tests: Fix CudaOnly.SeparateCompilationPTX test project nameBrad King2022-02-161-1/+1
| | | | | | | | | | | | Fix the test added by commit 61b9764b03 (CUDA: Allow both CUDA_SEPARABLE_COMPILATION and CUDA_PTX_COMPILATION, 2021-09-17, v3.23.0-rc1~516^2) to have a `project()` name matching what is passed to CTest's `--build-project` option. Otherwise, on VS builds, MSBuild warns: MSBUILD : error MSB1009: Project file does not exist. Other CUDA tests use a matching project name already.
* CUDA: Generic all and all-major supportRaul Tambre2022-02-011-34/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 14d8a276 (CUDA: Support nvcc 11.5 new -arch=all|all-major flags, 2021-08-17) added all and all-major options to CUDA_ARCHITECTURES. These are fairly generic and likely to see real-world use by distributors. Thus it's desirable to support these also for Clang and older NVCC versions. The supported architectures are dependent on the toolkit version. We determine the toolkit version prior to compiler detection. For NVCC we get the version from the vendor identification output, but for Clang we need to invoke NVCC separately. The architecture information is mostly based on the Wikipedia list with the earliest supported version being CUDA 7.0. This could be documented and expanded in the future to allow projects to query CUDA toolkit version and architecture information. For Clang we additionally constrain based on its support. Additionally the architecture mismatch detection logic is fixed, improved and updated for generic support: * Commit 01428c55 (CUDA: Fail fast if CMAKE_CUDA_ARCHITECTURES doesn't work during detection, 2020-08-29) enabled CMAKE_CUDA_COMPILER_ID_REQUIRE_SUCCESS if CMAKE_CUDA_ARCHITECTURES is specified. This results in CMakeDetermineCompilerID.cmake printing the compiler error and our code for presenting the mismatch in a user-friendly way being useless. The custom logic seems preferable so go back to not enabling it. * Commit 14d8a276 (CUDA: Support nvcc 11.5 new -arch=all|all-major flags, 2021-08-17) tried to support CMP0054 but forgot to add x to the interpolated result. Thus the conditions would always evaluate to false. This is fixed as a byproduct of removing NVIDIA specific checks, improving the error message and replacing architectures_mode with a simpler architectures_explicit. Visual Studio support omits testing the flags during detection due to complexities in determining the toolkit version when using it. A long-term proper implementation would be #23161. Implements #22860.
* CUDA: Visual Studio Generator propagates definitions for PTX filesunknown2021-12-143-0/+8
| | | | | | | | From CUDA 9.0 to CUDA 11.4 the CUDA Visual Studio integration defines omitted user defines from PTX generation. With CUDA 11.5 this has been resolved, so we backport the fix to allow for consistent behavior when using CMake
* CUDA: Support nvcc 11.5 new -arch=all|all-major flagsRobert Maynard2021-11-013-0/+49

* CUDA: Allow both CUDA_SEPARABLE_COMPILATION and CUDA_PTX_COMPILATIONRobert Maynard2021-10-206-1/+97
| | | | | | The target properties `CUDA_SEPARABLE_COMPILATION` and `CUDA_PTX_COMPILATION` now aren't mutually exclusive and can now be used together on the same target.
* CUDA/Clang: Fix separable compilation in non-root directories with Makefilesroot2021-07-294-21/+22
| | | | | | | | Seems the relative paths were wrong basically all around such that only compiling files in the top-level directory would work. I've modified CudaOnly.SeparateCompilation to cover this. Fixes #22482.
* FindCUDAToolkit: Robust version checks when CUDA lang is not enabledRobert Maynard2021-02-094-0/+39
| | | | | | Previously if you set `CMAKE_CUDA_COMPILER` but hadn't enabled the CUDA language, FindCUDAToolkit would not correctly compute the version information.
* CUDA: Fix tests with CUDAARCHS setRaul Tambre2020-11-302-1/+6
| | | | | | | With CUDAARCHS there's the possibility of tests being run with multiple architectures or having CMAKE_CUDA_ARCHITECTURES set with NVCC despite CMP0104 being OLD. Fix a few tests to work properly in such cases.
* CUDA: Clang separable compilationRaul Tambre2020-09-241-19/+17
| | | | | | | | | | | | For NVCC the compiler takes care of device linking when passed the "-dlink" flag. Clang doesn't support such magic and requires the buildsystem to do the work that NVCC does behind the scenes. The implementation is based on Bazel's device linking documentation: https://github.com/tensorflow/tensorflow/blob/7cabcdf073abad8c46e9dda62bb8fa4682d2061e/third_party/nccl/build_defs.bzl.tpl#L259 Closes: #20726
* Tests: Don't unnecessarily set CUDA_ARCHITECTURESRaul Tambre2020-09-219-28/+14
| | | | | | | | | | | | | | Architecture 30 was removed with CUDA 11, so most of the CUDA tests fail with it. Remove setting the architecture and bump the minimum version to 3.18, so CMP0104 takes effect and we can rely on the default architecture, which is guaranteed to be compilable. Use of __ldg() in ProperLinkFlags was removed as it only affects performance and is available only on sm_35 and above. Testing the functionality of CUDA_ARCHITECTURES is already covered by CudaOnly.Architecture and CudaOnly.CompileFlags.

| * CUDA: Compute CMAKE_CUDA_RUNTIME_LIBRARY default from toolchainRobert Maynard2020-05-213-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 0d0145138f (CUDA: Add abstraction for cuda runtime selection, 2019-11-29, v3.17.0-rc1~83^2) we add CUDA runtime library selection flags by default. To maintain backwards compatibility the default CUDA runtime library needs to be computed based on what libraries are found on the initial compiler invocation. For example a toolchain could establish initial flags that have all CUDA compilations using the runtime version, and if we don't detect this we will try to link to both the static and shared runtime.

* | Tests: Restore NVCC-specific CUDA testsBrad King2020-05-202-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit a653ca9504 (Tests: Update CUDA tests to work with Clang, 2020-03-27) some tests were conditioned using `CMAKE_CUDA_COMPILER_ID`. That is not defined when configuring CMake itself, so it accidentally turned off NVCC-specific CUDA tests altogether. Convert the conditions to check `CMake_TEST_CUDA` for `Clang` instead. That option is added explicitly to builds where we want the tests to run, so we can set it to a value indicating the CUDA compiler vendor. In commit a653ca9504 (Tests: Update CUDA tests to work with Clang, 2020-03-27) the NVCC-specific `CudaOnly.GPUDebugFlag` test was accidentally broken by removing a space when appending `-G` to the CUDA flags. This was covered by the test not running. Restore the space. Fixes: #20727
