Multifidelity DRAM Simulation in SST [Poster]
We will always want to speed up simulation. While architects are able to pick between levels of detail when designing simulation, we will find further speed-up if we can adjust the level of detail during simulation, depending on the behavior of the simulated components. We create a simple fixed-latency model for each phase. On the first execution of a phase, we record the average latency of accesses. On subsequent executions, we skip DRAMSin3 and send the response back using the average latency.
