PAGE404: Breaking GPU Isolation Through Hardware-assisted Page Migration

NVIDIA's Grace Hopper (GH200) superchip represents a new generation of heterogeneous computing, tightly integrating a 72-core Arm-based CPU with a Hopper GPU on a single module via a high-bandwidth, cache-coherent interconnect. By eliminating the conventional PCIe bottleneck for CPU-GPU data movement, this design estab...
