Due to the importance of collective communications in scientific parallel applications, many strategies have been devised for optimizing collective communications for different kinds of parallel environments. Recently, there has been an increasing interest to evolve efficient broadcast algorithms for computational Grids. In this paper, we present application-oriented adaptive tech-niques that take into account recent resource charac-teristics as well as the application’s usage of broad-casts for deriving efficient broadcast trees. In partic-ular, we consider two broadcast parameters used in the application, namely, the broadcast message sizes and the time interval between the broadcasts. The results indicate that our adaptive strategies can...
