Description
Summary:Future computing system designs will be constrained by power density and total system energy, and will require new programming models and implementation strategies. Data movement in the memory system and interconnect will dominate running time and energy costs, making communication cost reduction the primary optimization criteria for compilers. Communication cost can be divided into latency costs, which are per communication event, and bandwidth costs, which grow with total communication volume.
