CUDA Compilers

In general, check the crt/host_config.h file to find out which versions are supported. Sometimes it is possible to hack the requirements there to get some newer versions working, too :)

Thrust version can be found in $CUDA_ROOT/include/thrust/version.h.

Compatibility Guarantees


  • CUDA 10.0: First introduced in CUDA 10, the CUDA Forward Compatible Upgrade is designed to allow users to get access to new CUDA features and run applications built with new CUDA releases on systems with older installations of the NVIDIA datacenter GPU driver.
  • CUDA 11.1: First introduced in CUDA 11.1, CUDA Enhanced Compatibility provides two benefits:
    • By leveraging semantic versioning across components in the CUDA Toolkit, an application can be built for one CUDA minor release (such as 11.1) and work across all future minor releases within the major family (such as 11.x).
    • CUDA has relaxed the minimum driver version check and thus no longer requires a driver upgrade with minor releases of the CUDA Toolkit.
  • CUDA 12.4: Starting in CUDA 12.4, the NVIDIA driver installation on Linux will be opt-in. The goal is to improve user experience for a wide range of use cases such as installing the open module flavor driver. The cuda-runtime dependency and therefore the cuda-drivers (NVIDIA driver) dependency will be removed from the top-level cuda meta-package. Effectively, the cuda and cuda-toolkit meta-packages will be equivalent in CUDA 12.4.

CUDA version SM g++ icpc pgc++ xlC MSVC clang++ Linux driver thrust note

SM: means SM architecture support.

pgc++: now NVHPC products, e.g., nvc/nvfortran/nvc++.

Note: empty cells generally mean "same as above" for readability.

macOS: As of 7.0, clang seems to be the only supported compiler on OSX (but no version check found). CUDA 10.1.243 adds support for Xcode 10.2 . CUDA 11.0 dropped macOS support.

Compilers such as pgC, icc, xlC are only supported on x86 linux and little endian.

Dynamic parallelism was added with sm_35 and CUDA 5.0.

Newer CUDA releases have a per-release support matrix for compilers, which also lists supported kernel and glibc versions:

clang++ -x cuda

clang++ can compile CUDA C++ to ptx as well. Give it a whirl!

Great, Thanks.

ax3l commented Jan 2, 2021

@psychocoderHPC thank you for the update!

I updated the old clang versions, since the changelog does officially drop support for them. That means the library teams at Nvidia do not run CI against it anymore, so the range of usage will get narrower and less useful for those ancient compiler releases with modern CUDA releases (think: cuRand, cuBLAS, cuFFT, cub and thrust). Also, Nvidia libs transition all to C++14, so essentially you don't want to bother with gcc<5 and clang<5 anymore with CUDA11+.

With that disclaimer said, I updated the table accordingly nonetheless :) (putting ancient asserts in brackets)

@mabraham The documentation is in this file:
You could send a PR to and assign/request @Artem-B for a review :)

Artem-B commented Jan 5, 2021

latest supported CUDA is 10.1.
This is still true. This is the version for which clang implements all builtins needed by CUDA headers.
More recent CUDA versions will mostly compile and work as long as you don't happen to need the new compiler builtins. I.e. if you include mma.h or cuda_fp16.h when bf16/tf32 types are enabled in CUDA-11.x, things will likely break. Most of the code that compiles with CUDA-11.1 will still compile with newer CUDA versions, so clang issues a warning, but allows compilation to proceed. The results vary.

Copy link

ax3l commented Apr 10, 2021

You can check out the PyTorch documentation or use a from-source package manager like Spack (package: py-torch). This comment section is not the right place for support for specific CUDA-dependent software though, all we do is document CUDA compiler compatibility.

ax3l commented May 26, 2021

@Artem-B I was wondering, should the C++ standard default for -x cuda maybe be in lockstep with the Clang default for -x c++ to avoid confusion?

$ clang++-9 -dM -E -x c++  /dev/null | grep -F __cplusplus

Artem-B commented May 26, 2021

Huh. Interesting. I don't think we do anything special to set the default C++ version during CUDA compilation.
I suspect that whatever sets it only checks if the input language is C++, but does not pay attention to C++ extensions.

Yes, it would make sense to match the default version set by clang for C++. I'll get that fixed.

nvcc 11.4.1 now works again with g++ 10. Previous versions of nvcc choked somewhere in the chrono headers of libstdc++ IIRC.
Also g++ 11 is now supported with nvcc 11.4.1. I just successfully compiled an alpaka/LLAMA program with both combinations.

Thanks for the info @bernhardmgruber. So you say we should mark nvcc 11.1..11.4.0 as broken for g++10, right?

I am mainly happy that nvcc 11.4.1 supports g++11 now, which you updated, thx!

So you say we should mark nvcc 11.1..11.4.0 as broken for g++10, right?

Well, some versions of nvcc before 11.4.1 failed to parse the chrono headers. Whether that should be considered broken is beyond my judgement. Some people may not need this part of the stdlib and are fine. So I think your comment, that nvcc 11.4.1 fixes compilation of chrono, is good enough. Thanks!

CUDA 11.3.1 supports GCC 10.x, i.e. all GCC 10 minor versions, similar 11.4.1 supports all GCC 11 versions, so more complete:

  • 9.2 GCC < 8
  • 10.1 - 10.2 GCC < 9
  • 11.0 GCC < 10
  • 11.1 - 11.3 GCC < 11
  • 11.4 - 11.7 GCC < 12

And for Clang:

  • 10.2 Clang < 9
  • 11.1 Clang < 11
  • 11.2 - 11.3 Clang < 12
  • 11.4 - 11.5 Clang < 13
  • 11.6 - 11.7 Clang < 14

ax3l commented Nov 1, 2022

@Flamefire Thanks, that usually is right - I try to document the host compiler version known at release time and documented by Nvidia for the specific release to have been tested with. Minor releases of host compilers released after the CTK usually (but not always) work well together.

Updated the 11.3 and 11.4 tables accordingly to your tests - thanks a lot!

Glad to see that PyTorch cites us! :)

I found this page very useful - I am wondering if anyone is using github action for CI?

after github retires macos-10.5/xcode 10.0.3, I can non longer compile my cuda code using github's macos-11 and newer runners. see


a strange thing is that even I copy cuda 10.2 or 8 on the macos-11 runner and use the nvcc in these older cuda versions, it still complain Apple Clang or GNU GCC are not supported. It also appears to me that such error was not thrown by crt/host_config.h.

is there ANY way to build CUDA on macos 11 or newer?

Copy link

@fangq I'd just not bother with building CUDA on CI for macos anymore if CUDA support is dropped. What is the point of testing something if it cannot be run anymore? And it seems the latest working CUDA on macos is 10.2 and that only supports Clang <= 8.x
But if you really want you can try nvcc: -allow-unsupported-compiler as mentioned in the table above.

Copy link

fangq commented Jul 3, 2023

@Flamefire, I can't run any test from the runner anyways because it does not have GPU. I need it for building binaries for supported OSes. I statically link with cudart, so even cuda can not run on newer macos, a binary can still run as long as nvidia driver is installed.

I just tried the -allow-unsupported-compiler flag, unfortunately it has no effect, nvcc still complains that Apple Clang or GCC are not supported, nvcc 10.2 on macos 12; tried --allow-unsupported-compiler as well, same error.

@Flamefire, I can't run any test from the runner anyways because it does not have GPU. I need it for building binaries for supported OSes.

I meant: Is it worth building those binaries if they may not be run anymore (by users) as the OS stopped supporting CUDA (or the other way round)?

I just tried the -allow-unsupported-compiler flag, unfortunately it has no effect, nvcc still complains that Apple Clang or GCC are not supported, nvcc 10.2 on macos 12

This option has no effect on MacOS.

So there is no solution.

@ax3l I think the 11.4.0 for g++ is wrong. It only supports up to 10.X but the table shows compatibility with version 11. From my crt/host_config.h:

#if __GNUC__ > 10

#error -- unsupported GNU version! gcc versions later than 10 are not supported! The nvcc flag '-allow-unsupported-compiler' can be used to override this version check; however, using an unsupported host compiler may cause compilation failure or incorrect run time execution. Use at your own risk.

#endif /* __GNUC__ > 10 */
