Unified kernel policy dispatch — single entry point for ALL kernel configs.
Architecture directly mirrors CCCL cc_dispatch.cuh:
dispatch_compute_cap(policy_selector, cc, functor)
→ policy_getter<PolicySelector, CC>{}()
→ concrete policy struct
Our equivalent:
dispatch_kernel_config('attention', hw=BI_V100)
→ pre-computed AttentionConfig (frozen dataclass)
Includes:
- HardwareCapability (mirrors hardware.cuh bi_v100())
- AttentionConfig (mirrors ReducePolicy for V1/V2 dispatch)
- MoEConfig (mirrors TopkPolicy for fused_moe BLOCK_SIZE_M)
- TransformConfig (mirrors transform bytes_in_flight)
- CacheConfig (mirrors batch_memcpy threads)
- grid_even_share() (Python port of GridEvenShare::DispatchInit)
- check_smem() (SMEM constraint checker used by all policies)
- Pre-computed configs for Qwen3.6 at import time
(lowest_cc_resolver pattern: compute once, lookup always)
