jgrusewski 33864badf3 perf(cuda): TFT + Mamba2 forward passes fully GPU-native
TFT (10 downloads eliminated):
- lstm_encoder: gpu_select_dim1 per-timestep, gpu_cat_dim0 assembly
- variable_selection: gpu_narrow_2d column select, gpu_broadcast_mul_col
  weighted sum, gpu_mean_all per-column stats
- quantile_outputs: gpu_select_dim1 last timestep, gpu_stack_2d output,
  GPU quantile loss (sub→abs→scale→add→mean_all)
- mod.rs: GPU 3D broadcast for static context

Mamba2 (10 downloads eliminated):
- loss.rs: GPU MSE (sub→sqr→mean_all), GPU directional MSE with sign
  detection (mul→abs→div→scalar_sub→scale→mean_all)
- scan_algorithms: GPU sequential scan via gpu_select_dim1 per-step
- selective_state: GPU importance scoring (abs→mean_all)
- mod.rs: GPU state-space recurrence (select_dim1→matmul→add),
  GPU accuracy computation (sub→abs→relu→clamp→mean_all)

169/169 ml-supervised tests pass.

tli CLI commands and tooling

Services (8)

Service Purpose
backtesting_service gRPC backtesting service
broker_gateway_service FIX routing, broker connectivity
trading_service Core trading operations
ml_training_service Model training orchestration
data_acquisition_service Market data acquisition
trading_agent_service Autonomous trading agents
api_gateway gRPC API gateway with auth
web-gateway Axum REST + WebSocket gateway

Frontend

web-dashboard/ -- React 19 + TypeScript + Vite + TradingView charts.

Building

# Check compilation (no PostgreSQL required)
SQLX_OFFLINE=true cargo check --workspace

# Run tests for a specific crate
SQLX_OFFLINE=true cargo test -p <crate> --lib

# Clippy
SQLX_OFFLINE=true cargo clippy --workspace

ML Models

Four production model architectures on Candle v0.9.1 with CUDA:

  • DQN Rainbow -- Deep Q-Network with prioritized replay, dueling heads, noisy nets
  • PPO -- Proximal Policy Optimization with GAE and LSTM policies
  • TFT -- Temporal Fusion Transformer for multi-horizon forecasting
  • Mamba2 -- State space model for sequence prediction

Each model has a standalone trainer and a UnifiedTrainable adapter for the hyperopt pipeline.

Infrastructure

  • Git: Gitea at git.fxhnt.ai (Tailscale-only), Scaleway DEV1-S
  • Observability: OpenTelemetry OTLP (env OTEL_EXPORTER_OTLP_ENDPOINT)
  • Database: PostgreSQL with SQLx offline mode for CI
