Explain how GPU virtualization techniques are used to enable resource sharing and isolation in cloud computing environments, considering the challenges of performance isolation and security.

GPU virtualization enables the sharing and isolation of GPU resources among multiple virtual machines (VMs) or containers in cloud computing environments. This is crucial for maximizing resource utilization, reducing costs, and providing flexible GPU-as-a-Service offerings. However, achieving effective GPU virtualization involves addressing significant challenges related to performance isolation and security. *Resource Sharing: GPU virtualization allows multiple VMs to simultaneously access a single physical GPU, enabling efficient resource sharing. Without virtualization, each VM would require its own dedicated GPU, leading to underutilization and increased costs. Several techniques are used to enable GPU resource sh....
