Version 470.57.02(Linux)/471.41(Windows)

Release notes for the Release 470 family of NVIDIA® Data Center GPU Drivers for Linux and Windows.

This edition of Release Notes describes the Release 470 family of NVIDIA® Data Center GPU Drivers for Linux and Windows. NVIDIA provides these notes to describe performance improvements, bug fixes and limitations in each documented version of the driver.

1. Version Highlights

This section provides highlights of the NVIDIA Data Center GPU R470 Driver (version 470.57.02 Linux and 471.41 Windows).

For changes related to the 470 release of the NVIDIA display driver, review the file "NVIDIA_Changelog" available in the .run installer packages.

  • Linux driver release date: 07/20/2021
  • Windows driver release date: 07/20/2021

1.1. Software Versions

For this release, the software versions are listed below.

  • CUDA Toolkit 11: 11.4

    Note that starting with CUDA 11, individual components of the toolkit are versioned independently. For a full list of the individual versioned components (e.g. nvcc, CUDA libraries etc.), see the CUDA Toolkit Release Notes

  • NVIDIA Data Center GPU Driver: 470.57.02 (Linux) / 471.41 (Windows)

  • Fabric Manager: 470.57.02 (Use nv-fabricmanager -v)

  • GPU VBIOS:

    • 92.00.19.00.01 (NVIDIA A100 SKU200 with heatsink for HGX A100 8-way and 4-way)

    • 92.00.19.00.02 (NVIDIA A100 SKU202 w/o heatsink for HGX A100 4-way)

  • NVSwitch VBIOS: 92.10.14.00.01

  • NVFlash: 5.641

Due to a revision lock between the VBIOS and driver, VBIOS versions >= 92.00.18.00.00 must use corresponding drivers >= 450.36.01. Older VBIOS versions will work with newer drivers.

For more information on getting started with the NVIDIA Fabric Manager on NVSwitch-based systems (for example, HGX A100), refer to the Fabric Manager User Guide.

1.2. New Features

General

  • Added support for the following NVIDIA GPU products:

    • NVIDIA A16
    • NVIDIA A100 80 GB PCIe
  • Enabled new MIG profiles for the NVIDIA A30 where each of the 4 partitions has double the memory, 6GB up from 3GB per partition slice. See the MIG Device Names section of the NVIDIA MIG User Guide.
  • This release includes support for OpenCL 3.0

    Maintains backward compatibility with OpenCL 1.2. NVIDIA OpenCL 3.0 continues to support existing OpenCL 1.2 functionality as well as Khronos and vendor extensions that are already supported with NVIDIA OpenCL 1.2 drivers. The following new features beyond existing NVIDIA OpenCL 1.2 features are supported by NVIDIA OpenCL 3.0

    • RGBA vector component naming in OpenCL C kernels
    • pragma_unroll hint
    • opencl_3d_image_writes
    • clCreate*WithProperties APIs which can be used as replacement for existing clCreateBuffer/Image APIs.
    • clSetContextDestructorCallback
    • clCloneKernel from OpenCL 2.1
    • clEnqueueSVMMigrateMem from OpenCL 2.1
    • Incorporates the experimental 2.0 Device side enqueue

      The current implementation is limited to 64-bit platforms only, Allows kernels to be enqueued with global_work_size larger than the compute capability of the NVIDIA GPU. The current implementation supports only combinations of global_work_size and local_work_size that are within the compute capability of the NVIDIA GPU.

      The maximum supported CUDA grid and block size of NVIDIA GPUs is available at http://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#compute-capabilities. For a given grid dimension, the global_work_size can be determined by CUDA grid size x CUDA block size.

      For executing kernels (whether from the host or the device), OpenCL 3.0 supports non-uniform ND-ranges where global_work_size does not need to be divisible by the local_work_size. This capability is not yet supported in the NVIDIA driver, and therefore not supported for device side kernel enqueues.

      Note: Other OpenCL 2.X entry-points which are now optional and are not supported in NVIDIA OpenCL 3.0 will behave as described at https://www.khronos.org/registry/OpenCL/specs/3.0-unified/html/OpenCL_API.html#opencl-3.0-backwards-compatibility

1.3. Fixed Issues

  • Various security issues were addressed. For additional details on the med-high severity issues, review the NVIDIA Security Bulletin 5211 .

  • Fixed an issue with installing the Linux driver where installing the driver interferes with the ipmitool.

1.4. Known Issues

General

  • By default, Fabric Manager runs as a systemd service. If using DAEMONIZE=0 in the Fabric Manager configuration file, then the following steps may be required.
    1. Disable FM service from auto starting. (systemctl disable nvidia-fabricmanager)

    2. Once the system is booted, manually start FM process. (/usr/bin/nv-fabricmanager -c /usr/share/nvidia/nvswitch/fabricmanager.cfg). Note, since the process is not a daemon, the SSH/Shell prompt will not be returned (use another SSH shell for other activities or run FM as a background task).

  • On NVSwitch systems with Windows Server 2019 in shared NVSwitch virtualization mode, the host may hang or crash when a GPU is disabled in the guest VM. This issue is under investigation.

GPU Performance Counters

The use of developer tools from NVIDIA that access various performance counters requires administrator privileges. See this note for more details. For example, reading NVLink utilization metrics from nvidia-smi (nvidia-smi nvlink -g 0) would require administrator privileges.

NoScanout Mode

NoScanout mode is no longer supported on NVIDIA Data Center GPU products. If NoScanout mode was previously used, then the following line in the “screen” section of /etc/X11/xorg.conf should be removed to ensure that X server starts on data center products:

Option         "UseDisplayDevice" "None"

NVIDIA Data Center GPU products now support one display of up to 4K resolution.

Unified Memory Support

Some Unified Memory APIs (for example, CPU page faults) are not supported on Windows in this version of the driver. Review the CUDA Programming Guide on the system requirements for Unified Memory

CUDA and unified memory is not supported when used with Linux power management states S3/S4.

IMPU FRU for Volta GPUs

The driver does not support the IPMI FRU multi-record information structure for NVLink. See the Design Guide for Tesla P100 and Tesla V100-SXM2 for more information.

OpenCL 3.0 Known Issues

2. Virtualization

To make use of GPU passthrough with virtual machines running Windows and Linux, the hardware platform must support the following features:

  • A CPU with hardware-assisted instruction set virtualization: Intel VT-x or AMD-V.

  • Platform support for I/O DMA remapping.

  • On Intel platforms the DMA remapper technology is called Intel VT-d.

  • On AMD platforms it is called AMD IOMMU.

Support for these features varies by processor family, product, and system, and should be verified at the manufacturer's website.

Supported Hypervisors

The following hypervisors are supported:
