Abstract

Future exascale machines will require multi/many-core architectures able to energyciently run multi-threaded applications. Data-flow execution models have demonstrated to be capable of improving execution performance by limiting the synchronization overhead. This paper proposes to augment cores with a minimalistic set of hardware units and dedicated instructions that allow energyciently scheduling the execution of threads on the basis of data-flow principles. Experimental results show performance improvements of the system when compared with other techniques (e.g., OpenMP, Cilk).
