|
========
|
|
|
|
Introduction
|
|
------------
|
|
|
|
gpu-beta is a device management add-on that supports GPUs in containers. It supports only NVIDIA Tesla drivers.
|
|
|
|
Notes and Constraints
|
|
---------------------
|
|
|
|
- This add-on is available only in certain regions.
|
|
- This add-on can be installed only in CCE clusters of v1.11 or later.
|
|
- If GPU nodes are used in the cluster, the gpu-beta add-on must be installed.
|
|
- The driver to be downloaded must be a **.run** file.
|
|
- Only Tesla drivers are supported, not GRID drivers.
|
|
|
|
.. important::
|
|
|
|
- If the download link is a public network address, for example, **https://us.download.nvidia.com/tesla/396.37/NVIDIA-Linux-x86_64-396.37.run**, bind an EIP to each GPU node. For details about how to obtain the driver link, see :ref:`Obtaining the Driver Link from Public Network <cce_01_0141__section95451728192112>`.
|
|
- If the download link is an OBS URL, you do not need to bind an EIP to GPU nodes.
|
|
- Ensure that the NVIDIA driver version matches the GPU node.
|
|
- After the driver version is changed, restart the node for the change to take effect.

|
Installing the Add-on
|
|
---------------------
|
|
|
|
#. Log in to the CCE console. In the navigation pane, choose **Add-ons**. On the **Add-on Marketplace** tab page, click **Install Add-on** under **gpu-beta**.
|
|
|
|
#. On the **Install Add-on** page, select the cluster and the add-on version, and click **Next: Configuration**.
|
|
|
|
#. In the **Configuration** step, enter the link to download the NVIDIA driver.
|
|
|
|
#. Click **Install**.
|
|
|
|
After the add-on is installed, click **Go Back to Previous Page**. On the **Add-on Instance** tab page, select the corresponding cluster to view the running instance. This indicates that the add-on has been installed on each GPU node in the cluster.
|
|
|
|
Verifying the Add-on
|
|
--------------------
|
|
|
|
After the add-on is installed, run the **nvidia-smi** command on the GPU node and the container that schedules GPU resources to verify the availability of the GPU device and driver.
|
|
|
|
GPU node:
|
|
|
|
.. code-block::
|
|
|
|
cd /opt/cloud/cce/nvidia/bin && ./nvidia-smi
|
|
|
|
Container:
|
|
|
|
.. code-block::
|
|
|
|
cd /usr/local/nvidia/bin && ./nvidia-smi
|
|
|
|
If GPU information is returned, the device is available and the add-on is successfully installed.

Obtaining the Driver Link from Public Network
|
|
---------------------------------------------
|
|
|
|
#. Log in to the CCE console.
|
|
#. Click **Create Node** and select the GPU node to be created in the **Specifications** area. The GPU card model of the node is displayed in the lower part of the page.
|
|
|
|
3. Visit https://www.nvidia.com/Download/Find.aspx?lang=en.
|
|
|
|
4. Select the driver information on the **NVIDIA Driver Downloads** page, as shown in :ref:`Figure 1 <cce_01_0141__fig11696366517>`. **Operating System** must be **Linux 64-bit**.

6. Obtain the driver link in either of the following ways:
|
|
|
|
- Method 1: As shown in :ref:`Figure 3 <cce_01_0141__fig5901194614534>`, find *url=/tesla/396.37/NVIDIA-Linux-x86_64-396.37.run* in the browser address box. Then, supplement it to obtain the driver link https://us.download.nvidia.com/tesla/396.37/NVIDIA-Linux-x86_64-396.37.run. By using this method, you must bind an EIP to each GPU node.
|
|
|
|
- Method 2: As shown in :ref:`Figure 3 <cce_01_0141__fig5901194614534>`, click **AGREE & DOWNLOAD** to download the driver. Then, upload the driver to OBS and record the OBS URL. By using this method, you do not need to bind an EIP to GPU nodes.

Uninstalling the Add-on
|
|
-----------------------
|
|
|
|
#. Log in to the CCE console. In the navigation pane, choose **Add-ons**. On the **Add-on Instance** tab page, select the cluster and click **Uninstall** under **gpu-beta**.
|
|
#. In the dialog box displayed, click **Yes** to uninstall the add-on.
|
|
|
|
.. note::
|
|
|
|
The driver will not be uninstalled during gpu-beta add-on uninstall. If the driver is reinstalled, you must restart all GPU nodes.
