| | # Requirements |
| |
|
| | All requirements are applicable to the `main` branch on GitHub. |
| | For details on specific releases, please see the [changelog]. |
| |
|
| | ## Usage Requirements |
| |
|
| | To use the NVIDIA C++ Standard Library, you must meet the following |
| | requirements. |
| |
|
| | ### System Software |
| |
|
| | The NVIDIA C++ Standard Library requires either the [NVIDIA HPC SDK] or the |
| | [CUDA Toolkit]. |
| |
|
| | libcu++ was first released in NVHPC 20.3 and CUDA 10.2. |
| | Some features are only available in newer releases. |
| | Please see the [Standard API section], [Extended API section], and |
| | [release section] to find which features require newer releases. |
| |
|
| | Releases of libcu++ are only tested against the latest releases of NVHPC and |
| | CUDA. |
| | It may be possible to use a newer version of libcu++ with an older NVHPC or |
| | CUDA installation by using a libcu++ release from GitHub, but please be aware |
| | this is not officially supported. |
| |
|
| | ### C++ Dialects |
| |
|
| | The NVIDIA C++ Standard Library supports the following C++ dialects: |
| |
|
| | - C++11 |
| | - C++14 |
| | - C++17 |
| |
|
| | A number of features have been backported to earlier standards. |
| | Please see the [API section] for more details. |
| |
|
| | ### NVCC Host Compilers |
| |
|
| | When used with NVCC, the NVIDIA C++ Standard Library supports the following host |
| | compilers: |
| |
|
| | - MSVC 2017 and 2019. |
| | - GCC 5, 6, 7, 8, 9, and 10. |
| | - Clang 7, 8, 9, and 10. |
| | - ICPC latest. |
| | - NVHPC 20.9 and 20.11. |
| |
|
| | ### Device Architectures |
| |
|
| | The NVIDIA C++ Standard Library fully supports the following NVIDIA device |
| | architectures: |
| |
|
| | - Volta: SM 70 and 72. |
| | - Turing: SM 75. |
| | - Ampere: SM 80. |
| |
|
| | The following NVIDIA device architectures are partially supported: |
| |
|
| | - Maxwell: SM 50, 52 and 53. |
| | - Synchronization facilities are supported. |
| | - Pascall: SM 60, 61 and 62. |
| | - Blocking synchronization facilities (e.g. most of the synchronization |
| | library) are not supported. |
| | Please see the [synchronization library section] for details. |
| | |
| | ### Host Architectures |
| |
|
| | The NVIDIA C++ Standard Library supports the following host architectures: |
| |
|
| | - aarch64. |
| | - x86-64. |
| | - ppc64le. |
| |
|
| | ### Host Operating Systems |
| |
|
| | The NVIDIA C++ Standard Library supports the following host operating systems: |
| |
|
| | - Linux. |
| | - Windows. |
| | - Android. |
| | - QNX. |
| |
|
| | ## Build and Test Requirements |
| |
|
| | To build and test libcu++ yourself, you will need the following in addition to |
| | the usage requirements: |
| |
|
| | - [CMake]. |
| | - [LLVM]. |
| | - You do not have to build LLVM; we only need its CMake modules. |
| | - [lit], the LLVM Integrated Tester. |
| | - We recommend installing lit using Python's pip package manager. |
