Computer architects constantly seek to design faster, more powerful, and more power-efficient Central Processing Units (CPUs) and Graphics Processing Units (GPUs). But manufacturing a new design is a long and expensive process that relies on a previous verification for correctness and feasibility.

Multi2Sim is a simulator of CPUs and GPUs, used to test and validate new hardware designs before they are physically manufactured. By running a set of standard benchmarks on Multi2Sim, a computer architect can verify whether a proposed alternative design is correct, and what its relative performance is over existing designs.
