Version 440.95.01(Linux)/443.18(Windows)

This edition of Release Notes describes the Release 440 family of NVIDIA® Tesla® 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 Tesla 440 Driver, version 440.95.01 for Linux and 443.18 for Windows. For changes related to the 440 release of the NVIDIA display driver, review the file "NVIDIA_Changelog" available in the .run installer packages.

Driver release date: 6/24/2020

1.1. Fixed Issues

  • Various security issues were addressed, for additional details on the med-high severity issues please review NVIDIA Product Security for more information.

1.2. Known Issues

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.

NVML

NVML APIs may report incorrect values for NVLink counters (read/write). This issue will be fixed in a later release of the driver.

NoScanout Mode

NoScanout mode is no longer supported on NVIDIA Tesla 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 Tesla products:

Option         "UseDisplayDevice" "None"

Tesla 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.

Video Memory Support

For Windows 7 64-bit, this driver recognizes up to the total available video memory on Tesla cards for Direct3D and OpenGL applications.

For Windows 7 32-bit, this driver recognizes only up to 4 GB of video memory on Tesla cards for DirectX, OpenGL, and CUDA applications.

Experimental OpenCL Features

Select features in OpenCL 2.0 are available in the driver for evaluation purposes only.

The following are the features as well as a description of known issues with these features in the driver:

Device side enqueue

  • The current implementation is limited to 64-bit platforms only.

  • OpenCL 2.0 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#computecapabilities. 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 2.0 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.

Shared virtual memory

  • The current implementation of shared virtual memory is limited to 64-bit platforms only.


Driver branch:
r440_00-420 Windows
r443_18-13644 Linux Tesla (GRID version next week will have most likely a different kernel)
 
DriverVer   = 05/13/2020, 26.21.14.4318

Windows 10 driver also supports Quadros

Got the server back working after replacing motherboard
Running this with Server 2k19
Happily Folding @ Home with these
BUT no control panel, these might not be suited to Headless units (hence no CPL)
