众核任务映射算法研究现状与发展趋势

在众核系统中,并行任务在执行前需要被映射到处理器,这一过程被称为任务映射,任务映射算法对芯片性能影响巨大,所以近年来众核任务映射算法成为研究热点。针对不同的系统架构(如二维和三维众核系统)和优化目标(如通信开销、功耗、温度等)对现有任务映射算法进行综述,并展望了任务映射算法的未来发展趋势。

Current and Emerging Trends of Task Mapping in Many-Core Systems

In many-core systems,parallel tasks need to be mapped to processors before execution,which is referred as task mapping.Task mapping algorithms have a great impact on chip performance,and thus have attracted enthusiasm in the research community.Existing task mapping algorithms for different system architectures(such as 2D and 3D many-core systems)and optimization objectives(such as communication overhead,power consumption,temperature,etc.)are reviewed,and future research trends of task mapping algorithms are provided.
