Microarchitectural Modeling in the Era of Accelerator-Rich Systems and Computing at Scale
Dimitris Gizopoulos
Microarchitecture simulators have been conceived and implemented to be valuable tools for the design of computing chips of all types (SimpleScalar, gem5, SMTSIM, Sniper, Qflex, Scarab, GPGPU-sim, Accel-Sim, Multi2Sim, NaviSim, SCALE-sim, gem5-Salam, TAO, PyTorchSim – the list is neither historically complete nor updated). In essence, microarchitecture simulators have an “impossible” objective: to model and measure properties of a chip (and a complete system built on it) both quickly and...
