In PVM environment, multiple nodes work together to accomplish a large-scale computation task. However, the workload distribution among different nodes may vary during the execution of the program. This may cause load imbalance, which leads to poor performance of the system. Therefore, a proper load balancing strategy is needed to optimize the performance of PVM-based parallel computing.Objectives:The objective of this research is to design and implement a dynamic load balancing strategy for PVM environment. Specifically, we aim to achieve the following goals:1. Develop a load balancing algorithm that can adapt to dynamic workload changes.2. Implement the load balancing strategy in PVM environment.3. Evaluate the performance of the load balancing strategy using benchmark programs and real-world applications.Methodologies:To achieve the above objectives, we will follow the following methodologies:1. Review the related literature on load balancing strategies in PVM environment.2. Analyze the workload distribution characteristics of different applications in PVM environment.3. Design and implement a dynamic load balancing algorithm based on the analysis of workload distribution characteristics.4. Integrate the load balancing algorithm into PVM system and test its performance using benchmark programs and real-world applications.5. Analyze the experimental results and compare the performance of the proposed load balancing strategy with other existing strategies.Expected Outcomes:The expected outcomes of this research are:1. A dynamic load balancing algorithm that can adapt to dynamic workload changes in PVM environment.精品文档---下载后可任意编辑2. An implementation of the load balancing algorithm in PVM system.3.
