| Abstract: | In the network cluster system which is composed of some idle workstations to do distributed and parallel computing,it is one of primary issues to use what index to find idle workstations on the network and how to estimate the load level of a workstation so that to schedule processors dynamically.Based on the study of some current load index application in distributed systems,a new multiplex load index is proposed to satisfy network cluster computing system.Its function in the system is described in detail.The reasonable refreshing period of the load index is also discussed according to the lots of application measurements. |

| Keywords: | network cluster distributed and parallel computing load index refreshing period |
