jgrusewski 5149c71444 feat(gpu): warp-cooperative DQN experience kernel for H100 (sm_90+)
Add warp-cooperative CUDA kernel for DQN experience collection that
exploits H100's improved warp shuffle throughput. On sm_90+, 32 threads
(1 warp) cooperate on each dot product via __shfl_xor_sync butterfly
reduction, cutting per-thread register pressure from ~5.5KB to ~200B
and enabling full occupancy on 132 SMs.

Key additions:
- 6 warp-cooperative device functions in common_device_functions.cuh:
  distributed/broadcast matvec (clean + NoisyNet), warp RMSNorm,
  warp_reduce_sum_all
- 4 TILE_LAYER_WARP_* macros using __syncwarp() for warp-level sync
- 3 warp forward passes: standard dueling, NoisyNet, C51 distributional
  (distributed heavy layers + broadcast atom layers for softmax)
- Full warp kernel: dqn_full_experience_kernel_warp with lane-0
  simulation, strided state scatter, warp-shuffle curiosity gather
- Host-side compute capability detection (sm_major >= 9) with
  automatic fallback to standard 256-thread kernel on older GPUs
- cuCtxSetLimit(STACK_SIZE, 16KB) for standard kernel safety

874/874 tests pass, 0 clippy warnings.

ml

10-model ML ensemble for the Foxhunt HFT system, built on Candle v0.9.1.

Models

  • DQN (Rainbow) — deep Q-network with prioritized replay, dueling heads, noisy nets
  • PPO — proximal policy optimization with GAE, LSTM policies, clip-higher
  • TFT — temporal fusion transformer for multi-horizon forecasting
  • Mamba2 — state space model for sequence prediction
  • Liquid Networks — biologically inspired networks for non-stationary data
  • TLOB — transformer-based limit order book analysis
  • KAN — Kolmogorov-Arnold networks
  • xLSTM — extended LSTM architecture
  • TGGN — temporal graph neural network
  • Diffusion — diffusion-based generative model

Key Modules

  • ensemble — model ensemble coordination and confidence aggregation
  • hyperopt — PSO-based hyperparameter optimization with per-model adapters
  • trainers — unified training loops (DQN, PPO, supervised)
  • inferenceInferenceAdapter trait for prediction
  • checkpoint — model checkpointing and restoration
  • evaluation — walk-forward evaluation pipeline
