Method and device for improving calculating ability of virtual machine in resource monopolizing and exclusive mode
The invention discloses a method and device for improving calculating ability of a virtual machine in a resource monopolizing and exclusive mode. The method comprises the steps that firstly, a task is issued through a task issuing system, and whether the virtual machine needs high-performance calculating ability is described in the task; secondly, after a task executing system receives virtual machine building information, a virtual machine building module is called, and the virtual machine is built according to front-end input data; thirdly, after the virtual machine is built, according to requirements, if an appointed CPU needs to be monopolized, a new request for calling a CPU binding module is generated, and binding of a virtual machine VCPU is completed through the CPU binding module. By means of the method and device, in some specific scenes, for example, an oracle data base operates in the virtual machine, IO and concurrence ability of the virtual machine needs to be guaranteed. According to the method and device, by changing a CPU processing mode, the processing ability of the virtual machine can be improved.
