gem5-gpu is a new simulator that models tightly integrated CPU-GPU systems. It builds on gem5, a modular full-system CPU simulator, and GPGPU-Sim, a detailed GPGPU simulator. gem5-gpu routes most memory accesses through ruby, which is a highly configurable memory system in gem5. By doing this, it is able to simulate many system configurations, ranging from ...
