搭建MPI/CUDA开发环境

news 2024/12/23 16:34:35

本文记录MPI/CUDA开发环境搭建过程。

一、Linux

2.1 环境

操作系统	Ubuntu 22.04.4 LTS
VS Code	1.92.1
Git	2.34.1
GCC	11.4.0
CMake	3.22.1

2.2 VS Code

下载VS Code，然后安装以下插件，

Task Explorer Output Colorizer Git Extension Pack Git Graph Remote Developement Remote X11
C/C++ Extension Pack C++ TestMate
Modern Fortran FORTRAN InstelliSense Fortran Breakpoint Support
Python Extension Pack
C# Dev Kit
Extension Pack for Intel Software Developer Tools
Nsight Visual Studio Code Edition

2.3 oneAPI

# download the key to system keyring
wget -O- https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB 
| gpg --dearmor | sudo tee /usr/share/keyrings/oneapi-archive-keyring.gpg > /dev/nullecho "deb [signed-by=/usr/share/keyrings/oneapi-archive-keyring.gpg] https://apt.repos.intel.com/oneapi all main" | sudo tee /etc/apt/sources.list.d/oneAPI.listsudo apt updatesudo apt install intel-oneapi-base-toolkit
sudo apt install intel-oneapi-hpc-toolkit

2.4 CUDA

lspci | grep -i nvidia
uname -m && cat /etc/*release
gcc --versionwget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-keyring_1.1-1_all.deb
sudo dpkg -i cuda-keyring_1.1-1_all.deb
sudo apt-get update
sudo apt-get install cuda-toolkit
sudo reboot

运行以下命令测试CUDA安装成功，
