Exascale computing will get mankind closer to solving important social, scientific and engineering problems. Due to high prototyping costs, High Performance Computing (HPC) system architects make use of simulation models for design space exploration and hardware-software co-design. However, as HPC systems reach exascale proportions, the cost of simulation increases, since simulators themselves are...
As high performance computing (HPC) systems reach exascale proportions, the cost of simulation in time and resources increases. Tools for selecting representative parts of parallel applications to reduce simulation cost are widespread, e.g., BarrierPoint achieves this by analysing abstract characteristics such as basic blocks and reuse distances. However, architectures new to HPC will have a limited...
