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

1.2. Fixed Issues

  • Incorrect SMBPBI reporting of NVLINK will report 12 instead of 8 NVLINKs and errors when querying NVLINK status for 4 of the 12 possible NVLINKS.

1.3. Known Issues

General

  • On HGX A800 8-GPU systems, the nvswitch-audit tool will report 12 NVLinks per GPU. This is a switch configuration report and does not reflect the true number of NVLink interfaces available per-GPU, which remains 8.
  • Combining A800 and A100 SXM modules in a single server is not currently supported with this driver version.
  • Combining A800 and A100 PCIe with NVLink is not fully tested.
  • When switching between the Open and the legacy kernel modules on Ubuntu, use the following commands:

    In order to switch from open -> legacy:
    sudo apt-get remove --purge nvidia-kernel-open-515
    sudo apt-get install cuda-drivers-515
    In order to switch from legacy -> open:
    sudo apt-get remove --purge nvidia-kernel-source-515
    sudo apt-get install nvidia-kernel-open-515
    sudo apt-get install cuda-drivers-515
  • If you encounter an error on RHEL7 when installing with cuda-drivers-fabricmanager packages, use the following alternate instructions. For example:

    If you are upgrading from a different branch, for example to driver 515.65.01:

    new_version=515.65.01
    sudo yum swap nvidia-driver-latest-dkms nvidia-driver-latest-dkms-${new_version}
    sudo yum install nvidia-fabric-manager-${new_version}
  • When installing a driver on SLES15 or openSUSE15 that previously had an R515 driver installed, users need to run the following command afterwards to finalize the installation:

    sudo zypper install --force nvidia-gfxG05-kmp-default 

    Without doing this, users may see the kernel objects as missing.

  • nvidia-release-upgrade
    may report that not all updates have been installed and exit.
    When running the
    nvidia-release-upgrade
    command on DGX systems running DGX OS 4.99.x, it may exit and tell users: "Please install all available updates for your release before upgrading" even though all upgrades have been installed.
    Users who see this can run the following command:
    sudo apt install -y nvidia-fabricmanager-450/bionic-updates --allow-downgrades
    After running this, proceed with the regular upgrade steps:
    sudo apt update
    sudo apt full-upgrade -y 
    sudo apt install -y nvidia-release-upgrade 
    sudo nvidia-release-upgrade
  • 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).

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

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

Device side enqueue

2. Virtualization

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

  • 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.
