Multicore platform-orientated asymmetrical dispatcher for monitor of virtual machine and dispatching method thereof

The invention discloses an asymmetrical dispatcher for a multicore platform-orientated asymmetrical dispatcher for a monitor of a virtual machine and a dispatching method thereof, which provides a specialized service core meeting the special high performance demand is provided for a client operation system based on the conventional virtual machine monitor VMM. The dispatcher comprises a service core request resolution module in a management domain, a Domain specific service core configuration module in VMM, a system top dispatcher module, a service dispatcher module, a shared memory mechanism module and a request inquiry module, and a hybrid virtual module in an HVM Domain. The asymmetrical dispatcher in the invention not only can provide different service cores according to the demands of upper layer Domain, but also can provide higher flexibility and expandability than the traditional dispatcher due to the consideration of the topological structure of a physical platform during the distribution of the service cores. In addition, the dispatcher provides an acceleration mechanism of a specific application type for the client operation system and improves the service efficiency of the entire platform.

Video monitoring cloud resource prediction method and system

The invention provides a video monitoring cloud resource prediction method and system. The method comprises the following steps: a user request for video monitoring service is obtained; according to the request, and an initial resource distribution amount is determined, a current cloud intelligent video processing unit CIVU corresponding to the initial resource distribution amount is built; after current CIVU operation preset time, a first usage amount, in data corresponding to the current CIVU in a database, of video monitoring service resource in a first preset period before the current operation time is obtained; other usage mounts in a resource pool are traversed, and a first historical usage amount of which similarity to the first usage mount is greater than a preset threshold value is searched; according to the first historical usage amount, a variation quantity, in data corresponding to the current CIVU operation preset time in the database, of a second historical usage amount in an adjacent preset time period behind the second preset period is determined; according to the variation quantity and the first usage amount, a final resource demand amount of the user-requested video monitoring service resource in the CIVU in the adjacent preset time period after the first preset period can be predicted.

Polymerization type on-orbit structure-varying micro-nano satellite turn control method

The invention discloses a polymerization type on-orbit structure-varying micro-nano satellite turn control method, and relates to the field of micro-nano satellite design. The polymerization type on-orbit structure-varying micro-nano satellite turn control method comprises the following steps that S1, momentum wheels are arranged inside module satellites, and magnetic hinges and magnetic locking devices are arranged on the side edges; S2, in the initial state, the magnetic hinges are electrified, and the four magnetic locking devices corresponding to contact surfaces of the two module satellites are locked; S3, in the starting stage, the magnetic locking devices are unlocked, the momentum wheels push the module satellites to turn by taking relatively fixed edges as axes; S4, in a constant-speed turn stage, the turn module satellites turn at a constant speed; S5, in a speed reduction turn stage, the momentum wheels drive the turn module satellites to perform speed reduction turn; S6, the magnetic locking devices are locked, the two module satellites are relatively fixed, and the magnetic hinges are powered off. The polymerization type on-orbit structure-varying micro-nano satelliteturn control method has the advantages that quite high flexibility and expandability are achieved, structure vary of among all the components can be more conveniently performed, and requirements of elastic high-dynamic disaster reduction remote sensing application, large-scale space-based system construction and on-orbit maintenance service application and the like can be quite well achieved.
