1. Install WSL

1. In Windows 11, you can get WSL from Microsoft Store.

2. Run Ubuntu from the start menu and set a username and password. When finished you will see output like following:

   Installing, this may take a few minutes...
   Please create a default UNIX user account. The username does not need to match your Windows username.
   For more information visit: https://aka.ms/wslusers
   Enter new UNIX username: hangyi
   New password:
   Retype new password:
   passwd: password updated successfully
   The operation completed successfully.
   Installation successful!
   To run a command as administrator (user "root"), use "sudo <command>".
   See "man sudo_root" for details.

   This message is shown once a day. To disable it please create the

   hangyi@DESKTOP-VHIQPUO:~$
   

3. You can use the following commands to view system information.

   uname -a && lsb_release -a
   

   Output like this, I use Ubuntu 22.04.2 LTS:

   Linux DESKTOP-VHIQPUO 5.15.90.1-microsoft-standard-WSL2 #1 SMP Fri Jan 27 02:56:13 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
   No LSB modules are available.
   Distributor ID: Ubuntu
   Description:    Ubuntu 22.04.2 LTS
   Release:        22.04
   Codename:       jammy
   

4. If you exit, you can run wsl -d Ubuntu --cd ~ to return Ubuntu.

2. Install OpenMPI and OpenBLAS

0. If you are not confident about your network situation, it is recommended to configure a mirror source.

   sudo sed -i 's@//.*.ubuntu.com@//mirrors.ustc.edu.cn@g' /etc/apt/sources.list
   

   Running the above command will change your source address to the USTC mirror source. You may need to enter the password you set during the WSL installation.

1. Install the compile tools.

   sudo apt update && sudo apt install -y build-essential gfortran
   

2. Installing using the package manager should be the easy way out, but the version may be older.

   sudo apt install -y libopenmpi-dev libopenblas-dev
   

3. Test if the installation was successful:

   gcc --version && gfortran --version && mpirun --version && find /usr -name libmpi.so && find /usr -name libopenblas.a
   

   If the outputs like the following, it's OK:
