| Abstract: | A metasystem is a set of geographically distributed resources including hosts,databases and expensive instruments etc.being interconnected by high speed networks.These resources are heterogeneous in many aspects and may provide environment for applications execution.In this study, some batch-mode heuristics for mapping independent tasks to hosts on metasystem are discussed in detail, the model for scheduling tasks of Wade system is introduced,and the performance of several heuristics is compared. |
