Dr. Rosa Badia from BSC/CNS presented this Invited Talk at SC15. “StarSs (Star superscalar) is a task-based family of programming models that is based on the idea of writing sequential code which is executed in parallel at run-time taking into account the data dependencies between tasks. The talk will describe the evolution of this programming model and the different challenges that have been addressed in order to consider different underlying platforms from heterogeneous platforms used in HPC to distributed environments, such as federated clouds and mobile systems.”
