Problems solved by technology

The scheduling strategies adopted by most existing grid resource management and scheduling systems are only aimed at improving the throughput and utilization of the system and completing tasks in the earliest time, without considering resource access costs and user requirements for time and overhead. Takes into account, doesn't take the user's needs into account very well

Embodiment

[0091] Suppose a grid user has 8 tasks to execute, the lengths are 8000, 7000, 6000, 5000, 4000, 3000, 2000, 1000, the unit is MI, the Deadline and Budget set by the user are both 1000, and the system has 3 available resources R 1 , R 2 , R 3 , the execution speeds are 300MIPS, 500MIPS, 800MIPS respectively, and the overheads are 3.0, 5.0, 8.0 (unit: cents / sec).

[0092] When the time weight timeWeight=1 and the cost weight costWeight=0, the scheduling process is shown in the following table:

Abstract

Aiming at the problem of scheduling resources in the grid computing, the invention provides a scheduling method of grid resources of multi-Qos, which selects the most economic resource to schedule when in each scheduling. Compared with the prior art, the invention can complete the task at the least scheduling driving function value while meeting the user QoS, and realizes the satisfaction of a user to the max.

Description

technical field [0001] The invention relates to resource scheduling technology in grid computing, in particular to a multi-QoS grid resource scheduling method. Background technique [0002] Grid computing is rapidly developed along with Internet technology. It is a new computing model for complex scientific computing. It integrates the entire network into a huge supercomputer to realize computing resources, storage resources, data resources, information resources, and knowledge resources. , Comprehensive sharing of expert resources. Grid computing resources have become a trend to solve large-scale industrial scientific computing in modern society. However, the decentralized nature of grid computing resources determines that the cost of distributed computing based on cross-node communication is much higher than that of distributed computing in local area networks, and frequent communications cause considerable delay overhead. Improving parallelism is an important means to r...
