GPU GPU apparatus and method for interaction between a coarse-grained GPU resource scheduler and a GPU aware scheduler

摘要

The present invention provides a coarse-grained type GPU resource scheduler by a PCI express direct pass-through and a hot plug-in/plug-out method for smooth sharing a GPU between VMs. The present invention relates to a method for an interaction between the coarse-grained type GPU resource scheduler and a GPU recognition type scheduler which comprises the following steps. The GPU recognition type scheduler receives a virtual machine generation request signal in which the GPU can be used. The GPU recognition type scheduler transmits a GPU node searching signal in which a virtual machine in which the GPU can be used is mounted, to a GPU managing part. The GPU managing part corresponding to the GPU node searching signal transmits information related to a GPU node which can be used to the GPU recognition type scheduler. The GPU recognition type scheduler determines the GPU node to be allocated based on the information based on the GPU node which can be used.
