Users demand a better experience when using graphics-intensive applications. While it might be okay for a timecard form to load slightly slower, it’s not acceptable for a video to jitter.

Between the options of throwing more CPU at the problem or taking the vGPU route, the answer is obvious. And that’s is why we’re seeing rapid adoption of vGPU in VDI environments.

With ControlUp 7.1 we have introduced vGPU metrics to the ControlUp Real-Time Console. Let’s take a look at what’s possible with these new additions:

  • Static VM level metrics like vGPU Model and architecture, number of cores and driver version
  • Runtime VM level metrics like available memory, frame buffer size and amount allocated, video encoder, and encoder usage.
  • Runtime process level metrics show how many vGPU resources each relevant process consumes.

    In Computers view, we offer a detailed preset view of the NVIDIA GPU columns. This is a detailed explanation of the columns:

GPU Architecture

GPU's architecture name

GPU Available Memory

NVIDIA GPU available memory in megabytes (MB)

GPU Frame Buffer Size

Size of memory assigned to the NVIDIA GPU

GPU Frame Buffer Usage

NVIDIA GPU Frame Buffer usage in percents

GPU Memory Usage

NVIDIA GPU memory usage in percents

GPU Model

GPU name or NVIDIA GRID GPU profile type

GPU Number of Cores

Number of NVIDIA CUDA cores

GPU NVIDIA driver version

Current version of the installed NVIDIA GPU driver

GPU NVIDIA License Port

Primary NVIDIA license server port

GPU NVIDIA License Server

Primary NVIDIA license server name

GPU Usage

NVIDIA GPU usage in percents

GPU Video Decoder Usage

NVIDIA GPU video decoder usage in percents

GPU Video Encoder Usage

NVIDIA GPU video encoder usage in percents

Prerequisites

  • ControlUp Agent - must be installed on the machine where the GPU is installed.
  • NVIDIA WMI v2.30 - current version for 5.0,5.1,5.2.
  • GPU OS Support: 
    • Windows 7 64bit
    • Windows 8/8.1 64bit
    • Windows 10 64bit
    • Windows Server 2008 R2 64bit
    • Windows Server 2012 R2 64bit
    • Windows 2016 64bit
  • NVIDIA GRID Windows Driver Support: 
    • 5.0 - 385.41
    • 5.1 - 385.90
    • 5.2 - 386.09
  • Supported GPUs:
    • M6
    • M10
    • M60
    • P4
    • P6
    • P40
    • P100
  • Hypervisors Support:
    • All hypervisors supported by ControlUp 7.1

Known Issues

After rebooting a machine the ControlUP Agent goes up before the NVIDIA driver and then information is not being pulled properly from Nvidia's API. 

Solution:

  • Restart the ControlUp Agent by right clicking the machine > Agent Control > Restart Remote Agent. 

If you wish to change the Reg Keys for the number of retries to contact.

  • Registry path: HKEY_LOCAL_MACHINE\SOFTWARE\Smart-X\ControlUp\Agent\GPU (create GPU key)
  • Keys (DWORD):
    • NumberOfRetries - 5 by default
    • IntervalBetweenRetries - 60000ms by default

Tip

- Full utilization of your GPU can be shown in the command "nvidia-smi" (cmd)
