Recently, several programming models have been proposed that try to relieve parallel programming. One of these programming models is StarSs. In StarSs, the programmer has to identify pieces of code that can be executed as tasks, as well as their inputs and outputs. Thereafter, the runtime system (RTS) determines the dependencies between tasks and schedules ready tasks onto worker cores. Previous work...
To improve the programmability of multicores, several task-based programming models have recently been proposed. Inter-task dependencies have to be resolved by either the programmer or a software runtime system, increasing the respectively. In this paper we therefore propose the Nexus hardware task management support system. Based on the inputs and outputs of tasks, it dynamically detects dependencies...
An important question is whether emerging and future applications exhibit sufficient parallelism, in particular thread-level parallelism, to exploit the large numbers of cores future chip multiprocessors (CMPs) are expected to contain. As a case study we investigate the parallelism available in video decoders, an important application domain now and in the future. Specifically, we analyze the parallel...
