Abstract: It is currently an important research direction of network computing to build a dynamic non-dedicated cluster by using idle processors on a LAN. The most important issue of non-dedicated is the dynamic variety of network flow and communication delay. It is a major problem to induce the computing instability. This paper tries to analyze theoretically and estimate the influence of network flow to the various parallel tasks running in a non-dedicated cluster. The typical measurement results are provided.
