Abstract(in English) | This paper deals with upper and lower bounds of optimal execution time of task graphs that are supposed to be executed in a model of multiprocessor system, in which communication times are taken into account. We firstly define a path-dependent minimum subnet whose execution time is the shortest when executed by a single processor. Based on this definition, we then define a critical subnet of task graphs, which is the minimum subnet with the maximum execution time. Analyzing the properties of the minimum subnet and the critical subnet, we finally give the upper and lower bounds of optimal execution time of task graphs. |
