Virtuoso
Fast and Accurate Virtual Memory Research
A new simulation framework for fast and accurate prototyping of virtual memory designs through an imitation-based OS methodology
Fast & Lightweight
Virtuoso employs MimicOS, a lightweight userspace kernel that imitates only the required OS routines. This significantly speeds up simulation time than full-system Linux simulation.
Accurate
Virtuoso improves the accuracy of modeling the virtual memory subsystem. This way it improves performance estimation accuracy compared to traditional simulation methods.
Modular & Versatile
Virtuoso is designed with versatility in mind. You can easily extend it to evaluate new virtual memory schemes by integrating with diverse simulators like Sniper, gem5, Ramulator, and ChampSim.
