How To Get OpenCL Working with Nvidia 390 on Ubuntu 18.04

Ubuntu 1

In this article, we will guide you through the process of getting OpenCL to work with Nvidia 390 on Ubuntu 18.04. OpenCL (Open Computing Language) is a framework for writing programs that execute across heterogeneous platforms. It’s essential for running certain applications that leverage the power of GPU for processing.

Quick Answer

To get OpenCL working with Nvidia 390 on Ubuntu 18.04, you need to install the Nvidia 390 driver and the ocl-icd-libopencl1 package. After the installation, you can verify if OpenCL is working correctly by using the clinfo command.

Prerequisites

Before proceeding, ensure that you have administrative access to your Ubuntu 18.04 system and that the Nvidia 390 driver is installed. If not, you can install it using the following command:

sudo apt install nvidia-390

This command uses the sudo keyword to run the command as an administrator, apt is the package handling utility in Ubuntu, install is the command to install a package, and nvidia-390 is the package name.

Installing OpenCL Packages

To enable OpenCL support, you will need to install the ocl-icd-libopencl1 package. This can be done using the following command:

sudo apt install ocl-icd-libopencl1

The ocl-icd-libopencl1 package provides the Installable Client Driver (ICD) Loader for OpenCL. This allows applications to choose a platform from the list of installed platforms and offload computations to the GPU for processing.

Verifying the Installation

After the installation, you can verify if OpenCL is working correctly with the Nvidia 390 driver by using the clinfo command. If not installed, you can install it using:

sudo apt install clinfo

Then, run clinfo without any arguments:

clinfo

This command will display information about all available OpenCL platforms and devices in your system. If OpenCL is correctly set up, you should see your Nvidia GPU listed as one of the devices.

Troubleshooting

If you encounter any issues during the process, ensure that your Nvidia driver is correctly installed and updated. You can check the installed Nvidia driver version using the command:

nvidia-smi

This command will display information about your Nvidia driver and the GPU.

Conclusion

In this article, we have covered how to get OpenCL working with Nvidia 390 on Ubuntu 18.04. This process involves installing the ocl-icd-libopencl1 package and verifying the installation using clinfo. If you have followed all the steps correctly, you should now have OpenCL working with your Nvidia 390 driver.

Remember to always keep your system and drivers updated to ensure the best performance and security. For more information about OpenCL, you can refer to the official OpenCL documentation. For more information about Nvidia drivers, you can refer to the official Nvidia documentation.
