# System76 CUDA SDK + Tensorflow Packaging

Due to issues with how NVIDIA and Canonical package the CUDA toolkit, System76 is offering better

packaging for our users. This provides all of the debian packaging information needed to build

multiple versions of the CUDA toolkit in parallel, where the resulting packages may be installed

alongside each other. Users that install multiple toolkits only need to use `update-alternatives`

to switch between different versions of the toolkit.

> This repository is designed around our [debrep](https://github.com/pop-os/debrepbuild) tool. It

provides the means to generate and maintain apt repositories based on a TOML spec and file system

hierarchy. Using debrep, the data contained in the assets and debian directories are merged

together and built with `sbuild`, then stored in a repo pool.

## tensorflow-{cuda,cpu}

These packages are built with C, C++, and Python support. Similar to the CUDA packaging, it is

possible to alternate between different versions of Tensorflow. We backport fixes to older

versions of Tensorflow when possible. The build system we use is based on

[FloopCZ's work on a Cmake build system](https://github.com/FloopCZ/tensorflow_cc).

## system76-cuda Metapackage

The `cuda` directory contains the metapackage required by each of the toolkits. This installs the

required shared development dependencies, as well as some system configuration files to get toolkits

working out of the box. This package should be built and installed first on the build server.

## system76-cuda-X.Y Packages

The `cuda-X.Y` directories contain the specific versions of the toolkit, which depend upon the

`system76-cuda` metapackage built from the `cuda` directory. These can be built and installed in

parallel, as there are no conflicting files. `update-alternatives` is used post-install to add a

new entry for the symlink at `/usr/lib/cuda`. Each `cuda-X.Y` directory contains its own Makefile,

which will download the installer & patches for that release, if they are not already located in

the directory.

## Listing & Switching Between Toolkits

The `update-alternatives` command may be used to view installed toolkits, and switch between them.

```

sudo update-alternatives --list cuda

sudo update-alternatives --config cuda

```

You may verify that you have the correct toolkit active by checking the `version.txt` file

associated with that release of the toolkit:

```

$ cat /usr/lib/cuda/version.txt

CUDA Version 9.2.88

CUDA Patch Version 9.2.88.1

```
