GPGPU-Sim

GPGPU-Sim is a computer simulation tool that models how graphics processing units (GPUs) work. It allows researchers and developers to study and analyze GPU performance, behavior, and architecture without needing physical hardware. By mimicking how a GPU processes tasks, GPGPU-Sim helps optimize graphics and compute applications, guides hardware design, and improves understanding of GPU efficiency and bottlenecks, all within a controlled, virtual environment.
