Grace or Hopper? A Case Study of Wait-Free Concurrent Queues on the NVIDIA Grace Hopper GH200 Superchip
The NVIDIA GH200 Grace Hopper Superchip combines a Grace CPU and a Hopper GPU in a coherent CPU–GPU system whose architectural differences can expose different bottlenecks for device-local concurrent queues. Thus, this work leverages the CPU-based wait-free queue by Yang and Mellor-Crummey (YMC) as the basis for a case...
