Compiling the Source Code

Windows

• Download and install Visual Studio Community. In Visual Studio Installer, add:
  • Desktop development with C++
  • MSVC v142
  • Windows 10 SDK
• Download and unzip hw-smi.
• Open hw-smi.vcxproj in Visual Studio Community.
• Compile by clicking the ► Local Windows Debugger button.
• Go to hw-smi/bin/ folder and double-click hw-smi.exe.
• Alternatively, run from CMD:

  hw-smi.exe
  hw-smi.exe --graphs
  hw-smi.exe --bars
  hw-smi.exe --help

• Note that it will also work without administrator permissions. However, some telemetry counters on Intel GPUs are not available without administrator permissions.

Linux

• Clone from GitHub:

  git clone https://github.com/ProjectPhysX/hw-smi.git && cd hw-smi

• Compile:

  chmod +x make.sh
  ./make.sh

• Run:

  sudo bin/hw-smi
  sudo bin/hw-smi --graphs
  sudo bin/hw-smi --bars
  sudo bin/hw-smi --help

• Note that it will also work without sudo. However, some telemetry counters on Intel GPUs are not available without sudo.
