Dynamic Task Assignment In Server Farms: Better Performance By Task Grouping, Ling Tan, Z Tari

This paper describes a dynamic load balancing approach to distributed server farm systems. This approach overcomes the interference caused by non-negligible very-large tasks in the heavy-tailed distribution. First, a subset of tasks is allocated proportionally to the processing capability of participating servers by taking into account their remaining processing time. Later, tasks in the servers are processed in order of priority to optimise the system response time. The proposed load balancing algorithm also takes into account the information on server loads to avoid load imbalance caused by very large tasks. The experiments show that the mean waiting time and the …

One problem of propagating the globally fittest individual via neighbourhood evolution in both the island model and the cellular model of existing parallel genetic algorithms (PGAs) is that the migration of the globally best individual is delayed to non-adjacent processors. This may cause an inferior search in those sub-populations. The propagation delay of the globally best individual is proportional to the network distance between two processors. Delayed migration of the best individual in PGAs is an essential deviation from the sequential version of the genetic algorithm, in which the best individuals are always used to compete with other individuals. To …
