Embodiment 1

[0018] A method for real-time scheduling of cloud computing tasks, such as figure 1 As shown, the present embodiment includes the following steps: A) establishing a server node list S={s1, s2,..., sn}, n being the number of server nodes, establishing a communication time-consuming table T={T1, T2,...,Tn}, server node current task rate table L={L1,L2,...,Ln}.

[0019] B) Determine the computing power Csi according to the hardware configuration of the server node si, specifically: B1) Test several random server nodes s i, i ∈ d, d is the set of test server nodes, keep their CPU and memory running at full load for a period of time, calculate the amount of task data processed by server node si within the unit, as its computing power C si ; B2) computing server node s i , the average CPU computing power v of i∈d m1 , the average memory capacity v m2 , the average memory read and write speed v m3 , the average read and write speed of the hard disk v m4 And the average computin...

Abstract

The invention relates to the technical field of computers, in particular to a cloud computing task real-time scheduling method, which comprises the following steps of: A) establishing a server node list S, and establishing a communication time consumption table T and a load rate table L; b) determining the computing power Csi of the server node, and setting a performance score Psi; c) determiningthe required total computing power Ca according to the data volume and the task type of the new task; d) selecting a server node set D; e) dividing the new task into a plurality of sub-tasks, and allocating the sub-tasks to the server nodes in the set D, so as to enable the sub-tasks to be basically completed at the same time; and F) updating the server performance score Psi, and repeating the steps C-E. The method has the substantive effects that the available server resources of the real-time task are ensured and the response rate of the real-time task is improved by reasonably allocating the server computing power resources of the real-time task and the non-real-time task.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for real-time scheduling of cloud computing tasks. Background technique [0002] Cloud computing (Cloud Computing) represents the development frontier of fine-grained distributed parallel technology. It is a brand-new computing model that has developed rapidly in recent years. Large-scale distributed computing model. Cyber ​​Physical System (CPS for short) is a multi-dimensional complex system that integrates computing, network and physical environment through 3C (Computation, Communication, Control) technology. Real-time perception, dynamic control and information services. CPS is based on cloud computing technology, and the real-time performance of CPS is determined by the real-time performance of cloud computing. Therefore, it is necessary to develop a technical solution to improve the real-time performance of cloud computing tasks. [0003] For example, Chinese...
