Requirements

The list of required software to use the library includes:

• CUDA Toolkit 13.0+

• Supported CUDA compiler (C++17 required)

• Supported host compiler (C++17 required)

• (Optional) CMake (version 3.18 or greater)

Dependencies:

• commonDx (shipped with the MathDx package)

Important

Starting with nvCOMPDx 0.1.3, nvCOMPDx only supports CUDA Toolkit 13.0+.

For older versions of CUDA Toolkit, please use nvCOMPDx 0.1.2, which provides both cuda12 and cuda13 packages for users to choose from, supporting applications compiled using CUDA 12.6+ and CUDA 13.0+, respectively.

Important

LTO compatibility rules of CUDA:

• Compatibility within a CUDA Toolkit major version: Applications compiled with LTO using an older minor version (e.g., 13.0) can run on a newer minor version (e.g., 13.1) and their corresponding drivers

• Incompatibility across CUDA Toolkit major versions: Applications compiled with LTO using CUDA 12 cannot run on CUDA 13 and vice versa.

Supported Compilers

CUDA Compilers:

• NVCC 13.0+ (CUDA Toolkit 13.0 or newer)

• (Experimental support) NVRTC 13.0+ (CUDA Toolkit 13.0 or newer)

Host / C++ Compilers:

• GCC 7+

• Clang 9+ (Linux/WSL2 only)

• MSVC 19.44+ (Visual Studio 2022 version 17.14 and above)

Note

We recommend always using the latest CUDA Toolkit and NVCC compiler, along with GCC 9+.

Note

HPC SDK nvc++ is not yet supported as a host compiler in nvCOMPDx.

Note

nvCOMPDx emits errors for unsupported versions of the C++ standard. These errors can be silenced by defining NVCOMPDX_IGNORE_DEPRECATED_DIALECT during compilation, but nvCOMPDx is not guaranteed to compile or work correctly in such configurations.

Supported System Architectures

• x86_64

• AArch64

Warning

Compiling nvCOMPDx on certain ARM AArch64 architectures (sm_87, sm_103, and sm_121) is experimental, ONLY supported when using NVRTC and nvJitLink as presented in one of the examples.
