Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0027] The present invention first establishes a single-type closed queuing network model for a system that has only one type of request and includes fork-join operations, wherein each computing resource corresponds to a service center. The two input parameters required to analyze the model are the number of requests N and the service time D of each service center i . The number of requests N can be set according to the system load scale, and the service time of the service center is D i It can be obtained from the history records of the corresponding computing resources. Then the computer uses the horizontal decomposition method to decompose a single-type closed fork-join queuing network model into several product-type queuing network models. Such as figure 1 As shown, a fork-join operation consists of 2 pairs (F 1 -J 1 and F 2 -J 2 )’s single-class ...

Abstract

The invention discloses a method for analyzing performances of a single closed fork-join queuing network based on horizontal decomposition. The method is characterized in that a horizontal decomposition method is utilized to decompose a single closed fork-join queuing network model into a plurality of product-form queuing network models, thus an average value analysis method can be used to quickly solve the model, and the horizontal decomposition is only carried out on a queuing network comprising nested fork-joint operations once without recursive decomposition like a layer decomposition method, thereby greatly reducing the computational complexity, improving the efficiency that a computer computes and analyzes the single closed fork-join queuing network model, and promoting the computational performance.

Description

technical field [0001] The invention relates to the field of queuing network performance analysis, and mainly relates to a single-type closed bifurcation-convergence queuing network performance analysis method based on horizontal decomposition. Background technique [0002] Queuing Network (Queueing Network) model is a classic system performance analysis method, it uses a service center (Service Center) to describe a hardware and software resource, the whole system can be seen as a combination of several service centers according to certain relationships network of. The service center can be divided into two types: queue type and delay type: the queue type service center consists of a queue and several servers, the server is used to perform operations, and the queue is used to cache requests waiting for service; while the delay type service center Mainly used for simulating delay operation. The queue network model can be divided into open model (Open Model) and closed mode...
