What is NVTOP?

--------------



NVTOP stands for Neat Videocard TOP, a (h)top like task monitor for GPUs and

accelerators. It can handle multiple GPUs and print information about them in a

htop-familiar way.



Currently supported vendors are AMD (Linux amdgpu driver), Apple (limited M1 &

M2 support), Huawei (Ascend), Intel (Linux i915 driver), NVIDIA (Linux

proprietary divers), Qualcomm Adreno (Linux MSM driver).



Because a picture is worth a thousand words:

NVTOP Options and Interactive Commands

--------------------------------------

### Interactive Setup Window



NVTOP has a builtin setup utility that provides a way to specialize the interface to your needs.

Simply press ``F2`` and select the options that are the best for you.

### Saving Preferences



You can save the preferences set in the setup window by pressing ``F12``.

The preferences will be loaded the next time you run ``nvtop``.



### NVTOP Manual and Command line Options



NVTOP comes with a manpage!

```bash

man nvtop

```

For quick command line arguments help

```bash

nvtop -h

nvtop --help

```



GPU Support

-----------



### AMD



NVTOP supports AMD GPUs using the `amdgpu` driver through the exposed DRM and

sysfs interface.



AMD introduced the fdinfo interface in kernel 5.14 ([browse kernel

source](https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/gpu/drm/amd/amdgpu/amdgpu_fdinfo.c?h=linux-5.14.y)).

Hence, you will need a kernel with a version greater or equal to 5.14 to see the

processes using AMD GPUs.



Support for recent GPUs are regularly mainlined into the linux kernel, so please

use a recent-enough kernel for your GPU.



### Intel



NVTOP supports Intel GPUs using the `i915` linux driver.



Intel introduced the fdinfo interface in kernel 5.19 ([browse kernel

source](https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/gpu/drm/i915/i915_drm_client.c?h=linux-5.19.y)).

Hence, you will need a kernel with a version greater or equal to 5.19 to see the

processes using Intel GPUs.



**INTEL SUPPORT STATUS**

- Intel is working on exposing more hardware information through an `HWMON`

interface. The patches are still a work in progress: [see patch

series](https://patchwork.freedesktop.org/series/104278/).

- The fdinfo interface does not expose the memory allocated by the process. The

field in the process list is therefore empty.



### NVIDIA



The *NVML library* does not support some of the queries for GPUs coming before the

Kepler microarchitecture. Anything starting at GeForce 600, GeForce 800M and

successor should work fine. For more information about supported GPUs please

take a look at the [NVML documentation](http://docs.nvidia.com/deploy/nvml-api/nvml-api-reference.html#nvml-api-reference).



### Adreno



NVTOP supports Adreno GPUs using the `msm` linux driver.



msm introduced the fdinfo interface in kernel 6.0 ([browse kernel

source](https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/gpu/drm/msm/msm_drv.c?h=linux-6.0.y)).

Hence, you will need a kernel with a version greater or equal to 6.0 to see the

processes using Adreno GPUs.



### Apple



NVTOP includes some initial support for Apple using Metal. This is only supported when building for Apple, and when building for Apple only this vendor is supported.



**APPLE SUPPORT STATUS**

- Apple support is still being worked on. Some bugs and limitations may apply.



### Ascend



NVTOP supports Ascend (testing on Altas 800 (910B)) by DCMI API (version 6.0.0).



Currently, the DCMI only supports limited APIs, missing PCIe generation, tx/rx throughput info, max power draw etc.



Build

-----



Several libraries are required in order for NVTOP to display GPU info:



* The *ncurses* library driving the user interface.

  * This makes the screen look beautiful.

* For NVIDIA: the *NVIDIA Management Library* (*NVML*) which comes with the GPU driver.

  * This queries the GPU for info.

* For AMD: the libdrm library used to query AMD GPUs through the kernel driver.



## Distribution Specific Installation Process

- ```bash

  # Go to the download location ** The path may differ on your system **

  cd $HOME/Downloads

  # Make the AppImage executable

  chmod u+x nvtop-x86_64.AppImage

  sudo docker run -it --rm --runtime=nvidia --gpus=all --pid=host nvtop

  ```



## NVTOP Build



```bash

git clone https://github.com/Syllo/nvtop.git

mkdir -p nvtop/build && cd nvtop/build

cmake .. -DNVIDIA_SUPPORT=ON -DAMDGPU_SUPPORT=ON -DINTEL_SUPPORT=ON

make



# Install globally on the system

sudo make install



# Alternatively, install without privileges at a location of your choosing

# make DESTDIR="/your/install/path" install

```



If you use **conda** as environment manager and encounter an error while building NVTOP, try `conda deactivate` before invoking `cmake`.



The build system supports multiple build types (e.g. -DCMAKE_BUILD_TYPE=RelWithDebInfo):



* Release: Binary without debug info

* RelWithDebInfo: Binary with debug info

* Debug: Compile with warning flags and address/undefined sanitizers enabled (for development purposes)



Troubleshoot

------------



- The plot looks bad:

  - Verify that you installed the wide character version of the ncurses library (libncurses**w**5-dev for Debian / Ubuntu), clean the build directory and restart the build process.

- **Putty**: Tell putty not to lie about its capabilities (`$TERM`) by setting the field ``Terminal-type string`` to ``putty`` in the menu

  ``Connection > Data > Terminal Details``.
