# System Requirements

Linux and WSL

On all Linux platforms, NVIDIA Nsight Compute CLI requires GLIBC version 2.15 or higher. On x86_64, the NVIDIA Nsight Compute UI requires GLIBC version 2.17 or higher. On Linux (aarch64 sbsa), the NVIDIA Nsight Compute UI requires GLIBC version 2.26 or higher.

The NVIDIA Nsight Compute UI requires several packages to be installed to enable Qt. Please refer to the Qt for X11 Requirements. When executing `ncu-ui` with missing dependencies, an error message with information on the missing packages is shown. Note that only one package will be shown at a time, even though multiple may be missing from your system. For selected operating systems, the following commands install needed packages for NVIDIA Nsight Compute on X11:

- Ubuntu 18.04

  `apt install libopengl0 libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-render-util0 libxcb-xkb1 libxkbcommon-x11-0`

- Ubuntu 20.04

  `apt install libopengl0 libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-render-util0 libxcb-xinerama0 libxcb-xkb1 libxkbcommon-x11-0`

- RHEL 8.6

  `yum install libglvnd-opengl libxcb libxkbcommon-x11`

Profiling on Windows Subsystem for Linux (WSL) is only supported with WSL version 2. Profiling is supported on Windows 10 WSL with OS build version 19044 and greater, and NVIDIA display driver version 545 or higher. It is not supported on Windows 10 WSL for systems that exceed 1 TB of system memory. Profiling is supported on Windows 11 WSL with NVIDIA display driver version 525 or higher.

The Linux (x86_64) NVIDIA Nsight Compute package can be used and should be installed directly within WSL2. Remote profiling to and from WSL2 works equivalently to regular Linux (x86_64) hosts and targets, as long as it’s accessible via SSH. Access to NVIDIA GPU Performance Counters must be enabled in the NVIDIA Control Panel of the Windows host. See also the CUDA on WSL User Guide.

Windows

Only Windows 10 and 11 are supported as host and target.

The Visual Studio 2017 redistributable is not automatically installed by the NVIDIA Nsight Compute installer. The workaround is to install the x64 version of the ‘Microsoft Visual C++ Redistributable for Visual Studio 2017’ manually. The installer is linked on the main download page for Visual Studio at https://www.visualstudio.com/downloads/ or download directly from https://go.microsoft.com/fwlink/?LinkId=746572.
