Abstract:Abstract. This paper focuses on two problems related to QoS-aware I/O server placement in hierarchical Grid environments. Given a hierarchical network with requests from clients, the network latencies of links, constraints on servers' capabilities and the service quality requirement, the solution to the minimum server placement problem attempts to place the minimum number of servers that meet both the constrains on servers' capabilities and the service quality requirement. As our model considers both the diffe… Show more
