Key Takeaway

The NOCL project implements the Mesa Gallium3D API on top of NVIDIA's CUDA driver API, providing an open-source OpenCL option for the official NVIDIA Linux driver.

Summary

The NOCL project, formerly known as CLUDA, has been in development for the past year and provides a compute-only Gallium driver for use with the NVIDIA proprietary driver. This driver uses the NVIDIA CUDA driver and leverages the NVIDIA PTX representation. The project aims to provide an open-source OpenCL option for the official NVIDIA Linux driver and supports more OpenCL extensions than the NVIDIA OpenCL proprietary driver.

What's Changing with NOCL

  • NOCL provides an open-source OpenCL option for the official NVIDIA Linux driver
  • Supports more OpenCL extensions than the NVIDIA OpenCL proprietary driver
  • Uses the NVIDIA CUDA driver and leverages the NVIDIA PTX representation

Why it matters

The NOCL project can be useful for performance comparisons and as a development exercise around the NVIDIA PTX IR, and its PTX-to-NIR support will be important for the likes of DLSS with the NVK Mesa driver.
