| Abstract: | Network parallel computing is one of the important branches of parallel and distributed computing technology.With numerical experiments,several important factors affecting the performance of PVM parallel programs in PVM network parallel numerical computing under Windows operation systems are discussed,which relate to load-balancing,communication costs,network performance,task granularity,the number of processors,precision requirement of the problem to be solved and the computer's memory capacity.At the same time,the corresponding strategies for improving the performance of PVM parallel programs are also explored,so as to solve the problem efficiently and quickly. |
