In contrast, a high-end GPU might have 2000 to 5000 cores, but they aren't each able to run completely different instructions at the same time.
Servers fitted with GPUs probably need two sets of patches, covering both the NVIDIA GPU drivers that control the actual hardware in the physical system, and the NVIDIA vGPU software, which shares out physical GPUs between guest operating systems running under virtualisation software from vendors including Citrix, Red Hat and VMWare.
NVIDIA's virtual GPU drivers help to share out the physical GPUs in the host computer between VMs that need them, allowing GPU-intense tasks such as machine learning and molecular modelling to be split up between virtual machines, just like conventional programs such as web servers.
Patches have been announced for NVIDIA Geoforce, Quadra, NVS and Tesla GPUs on both Windows and Linux.
There are also updates for NVIDIA Virtual GPU guest drivers for Windows and Linux, as well as for the NVIDIA Virtual GPU Management software.
