# Red Hat\* 8.1

To install the latest general purpose GPU (GPGPU) software packages on
Red Hat 8.1, add the Intel(R) software package repository and
install the appropriate packages.

## Add package repository

To install the **repositories.intel.com/graphics** package repository, add the
following to your RHEL installation. Prior to copy/pasting to your console,
you may want to run `sudo ls` and enter your password to prevent the commands
from being swallowed by the sudo password prompt:

```bash
sudo dnf install -y 'dnf-command(config-manager)'
sudo dnf config-manager \
  --add-repo \
  https://repositories.intel.com/graphics/rhel/8.1/intel-graphics.repo
```

The above will make sure your system has the config-manager plugin for dnf
installed. It will then use the config-manager to install the repository.

## Install run-time packages

After adding the repository, you can install the GPU software packages by
running the following:

```bash
sudo dnf update --refresh
sudo dnf install \
  intel-opencl \
  intel-media intel-mediasdk \
  level-zero intel-level-zero-gpu
```

If this is the first time you have installed a package from this repository,
you may be prompted to import the GPG key. Select 'y' to accept the key.

### OPTIONAL: Install developer packages

If you will be doing development, you may want to install optional development
packages. oneAPI users will need to install these packages for some of the
oneAPI tools to function correctly:

```bash
sudo dnf install \
  intel-igc-opencl-devel \
  intel-igc-cm \
  level-zero-devel
```

### Configuring permissions

To access GPGPU capabilities, a user needs to have the correct 
permissions. The following will list the group assigned ownership of the 
render nodes, and list the groups the active user is a member of:

```bash
stat -c "%G" /dev/dri/render*
groups ${USER}
```

If a group is listed for the render node which isn't listed for the user,
you will need to add the user to the group using gpasswd. In the following,
the active user will be added to the 'render' group and a new shell spawned
with that group active:

```bash
sudo gpasswd -a ${USER} render
newgrp render
```
