Problems solved by technology

[0006] The traditional cloud data center task management technology always sets a constant size window of acceptable new tasks. This technology has the following disadvantages: it does not consider the dynamic changes in the load of the physical machine, and it is easy to process the remaining tasks on the physical machine. A large number of new tasks are still arranged under the condition of rapid load growth, which leads to task congestion after a period of time after task distribution, and the system performance drops sharply; In the case of a decline, fewer new tasks are still scheduled, resulting in a situation where the physical machine is idling after a period of time after the task is distributed, causing a waste of computing resources

Embodiment Construction

[0111] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0112] Such as figure 1 As shown, a method for dynamically controlling the number of newly added tasks in the cloud data center, assigning tasks to the cloud data center according to the interval time t, is carried out according to the following steps:

[0113] Step 1. Obtain system information, where the system information is cloud data center information. The system information includes: the number of tasks added to the data center in this round XZT x , The number of tasks completed by the data center in this round WCT x , the number of tasks currently running on each physical machine in the data center DQT i and the number of task migrations QYT of each physical machine in this round i . Where 1≤i≤WLJ, WLJ is the number of physical machines in the data center. The subscript x represents the number of rounds. Since the system is analyzed and controlle...

Abstract

The invention discloses a dynamic control device, system and method for the number of newly added tasks in a cloud data center, belonging to the field of cloud computing. It can withstand the forecast value of new tasks, dynamically determine the size of the new task window, avoid task congestion and computing resource idling, achieve an optimal balance, and take into account the performance and economy of the cloud system.

Description

technical field [0001] The invention belongs to the field of cloud computing, and in particular relates to a dynamic control device, system and method for the number of newly added tasks in a cloud data center. Background technique [0002] Cloud computing refers to a computing model that distributes tasks on a large number of distributed computers, uses a cloud computing platform, and provides users with information services through the network. Compared with traditional software forms, cloud computing has significant advantages such as loose coupling, on-demand, cost control, resource virtualization, and heterogeneous collaboration, making it more suitable for today's e-commerce, flexible manufacturing, and mobile Internet applications. Cloud computing includes two meanings: one is the underlying cloud computing platform infrastructure, which is the basis for building upper-layer applications; the other is the cloud computing applications built on this basic platform.
