Gpu memory pool manager for virtual shared gpu memory pooling

Abstract

Disclosed methods provide a virtualized shared graphics processing unit (GPU) memory pool (VSGMP) to virtual machines running on an information handling system. The VSGMP may be implemented with a GPU memory pool (GMP) manager, featuring logic for abstracting the GPU memory pool from the physical memory resources of two or more GPUs. The GMP manager logic may be supported by a lightweight secure operating system (LSOS) capable of enabling functionality for virtualization and other use cases. Disclosed methods manage GPUs in an information handling system featuring two or more GPUs running virtual machines (VMs). When a GPU is assigned to a VM, disclosed methods perform one or more GPU resource allocation operations that support virtual shared pooling of the physical memory resources of two or more GPUs. In at least some embodiments, the GPU allocation operations include allocating at least some non-memory resources of the GPU exclusively to the applicable VM.
