| Abstract: |
| Communication overhead in massively paralleI processing systems is an im-portant factor which affects the performance of MPP．Broadcasting is a communication method used frequently in MPP systems．If broadcasting can be implemented as quickly as possible，then the performance of system will be increased．Based on the TORUS inter-connection network，this paper proposes the pipelining broadcasting，analyses its perfor mance and shows that pipeline broadcasting can derease the broadcasting delay and im- prove the performance of MPP systems． |
| Key words: Broadcast,pipeline,multicomputer,TORUS network． |
