GPUs support by default an equal share and have to configure a fixed share as per a customer’s requirement.

We can configure GPU with the following two options:

• Equal share scheduler: A physical GPU is shared among all the virtual desktops as vGPUs running on the same host. The share of processing cycles changes as vGPUs are added/removed to a GPU and the performance of a vGPU depends on whether other vGPUs are running or stopping.
• Fixed share scheduler: Each vGPU is allocated a fixed share of the physical GPU's processing cycles in spite of whether vGPUs are added to or removed from a GPU. It will be constant, even if other vGPUs are running or stopping.

NVIDIA GRID vGPU on vSphere can be configured with various options for the vGPU profile that defines the GPU memory each VM can use with the maximum number of VMs that can share a single GPU.

vGPU profiles provides a line up of virtual GPUs with different buffer memory frame sizes and numbers of heads. The number of users will be defined by the division of a frame buffer per GPU attached to a specific profile, and the number of heads denotes the supported number of displays, while the maximum resolution will be consistent across all the profiles. vGPU profiles ending in Q have to follow an application certification process the same as the NVIDIA Quadro cards for professional graphics applications. We can get 100% compatibility and performance with these applications.
