Abstract: Grid is a complex distributed computing system, distributed deployment and QoS performance analysis of grid services scheduling algorithm were studied. State space model was given to describe the grid dynamic scheduling system which processes a number of heterogeneous jobs concurrently. Clearing policy as a scheduling poficy and services sched uling algorithm were given. Distributed deployment problem was analyzed. System QoS performance parameters were calculated, stable throughput and stable response time and their relationship with load factor were pointed.

Key words: Grid, Services scheduling algorithm, Distributed deployment, Performance analysis
