What Irregularity Costs: CUDA C++, Rust, and Triton on a Hash-Blocked GPU Workload
This work implements the same hash-blocked TSDF fusion kernel in CUDA C++, in Rust through NVIDIA's cuda-oxide, and in Triton, and measures it on a workload with the opposite character: an open-addressed hash table with compare-exchange insertion, data-dependent per-lane probe depth, and contended scatter.
