Abstract: Frames of a virtual desktop are encoded using a hybrid approach that combines the strength of software encoding by a central processing unit (CPU) and hardware encoding by a graphics processing unit (GPU). A method of encoding frame data of one or more virtual desktops in hardware and in software and transmitting the encoded frame data to one or more client devices, includes the steps of encoding a first portion of the frame data in the GPU to generate a first encoded frame data, encoding a second portion of the frame data in software, i.e., programmed CPU, during encoding of the first portion, to generate a second encoded frame data, and transmitting the first encoded frame data and the second encoded frame data from a host computer of the one or more virtual desktops to the one or more client devices as separate video streams.

Abstract: Methods, techniques, and systems for dynamically allocating graphics processing units among virtual machines are provided. Example embodiments provide a dynamic GPU allocation system (“DGAS”), which enables the efficient allocation of physical GPU resources to one or more virtual machines. In one embodiment, the DGAS determines runtime profiles of a plurality of virtual machines. The runtime profiles are determined by determining a runtime assessment of workload indicative of a potential benefit that the virtual machine can receive from using a GPU resource. The DGAS then causes the processing bandwidth of the physical GPU resources to be allocated to some of the plurality of virtual machines based upon the dynamically determined runtime assessments of workload.

Abstract: Methods, techniques, and systems for dynamically allocating graphics processing units among virtual machines are provided. Example embodiments provide a dynamic GPU allocation system (“DGAS”), which enables the efficient allocation of physical GPU resources to one or more virtual machines. In one embodiment, the DGAS comprises a GPU allocation list for use in allocating the physical GPU resources comprising one or more virtual machine entries each containing a designation of a virtual machine, an indication of a GPU benefit factor associated with the designated virtual machine, and an indication of processing bandwidth requirements associated with the designated virtual machine. The entries are ranked based at least upon the GPU benefit factor associated with each designated virtual machine. Available GPU resources are allocated to some subset of these ranked virtual machines as physical GPU capacity is matched with the requirements of the subset.

Abstract: Methods, techniques, and systems for dynamically allocating graphics processing units among virtual machines are provided. Example embodiments provide a dynamic GPU allocation system (“DGAS”), which enables the efficient allocation of physical GPU resources to one or more virtual machines. In one embodiment, the DGAS comprises virtualization logic running on a server computing system that computes GPU benefit factors for the virtual machines on a dynamic basis, and combines the computed GBFs with static priorities to determine a ranked ordering of virtual machines. The available GPU resources are then allocated to some subset of these ranked virtual machines as physical GPU capacity is matched with the requirements of the subset. Physical GPU resources are then allocated to the subset of virtual machines that have the highest promise of GPU utilization.
