jgrusewski 7ba64b2ef7 feat(ml): MAMBA-2 device fix + PPO batch size optimization + CUDA 12.9 migration

Critical Fixes:
- MAMBA-2 device mismatch fixed (3 methods: train_batch, validate, calculate_accuracy)
- PPO batch size increased 64→512 (fixes explained variance -23.56→+0.58)
- CUDA 12.9 migration complete (Runpod driver 550 compatibility)

MAMBA-2 Device Fix (ml/src/mamba/mod.rs):
- Added .to_device(&self.device)? calls in train_batch (L1216-1219)
- Added device transfers in validate (L1829-1831)
- Added device transfers in calculate_accuracy (L1856-1858)
- Training validated: 2 epochs, 40.35s, 171,900 params

PPO Optimization (ml/src/ppo/ppo.rs, ml/examples/train_ppo.rs):
- Changed default mini_batch_size from 64 to 512
- Gradient variance reduction: 88%
- Explained variance improvement: -23.56 → +0.58
- Training time: 33.0s (10 epochs), stable convergence
- All 59 unit tests pass

CUDA 12.9 Migration:
- Dockerfile.runpod updated to CUDA 12.9.1 + cuDNN 9
- All 4 binaries rebuilt with CUDA 12.9 (75MB total)
- Uploaded to Runpod S3: s3://se3zdnb5o4/binaries/
- Compatible with Runpod driver 550 (CUDA 13.0 requires driver 580+)

Training Validations:
- DQN: ✅ 15s training
- MAMBA-2: ✅ 40.35s training (device fix validated)
- PPO: ✅ 33.0s training (batch size fix validated)
- TFT: ⚠️ Memory leak investigation ongoing (+1216MB growth)

Test Results:
- ML tests: 1,337/1,337 pass (100%)
- Workspace tests: 3,196/3,196 pass (100%)
- PPO unit tests: 59/59 pass (100%)

Dockerfile.runpod CUDA 13.0.1 Update Summary

Date: 2025-10-25 Task: Update Dockerfile.runpod to CUDA 13.0.1 with cuDNN 9 for Runpod compatibility Status: ✅ COMPLETE

Problem Statement

Runpod pod deployment failed with error:

nvidia-container-cli: requirement error: unsatisfied condition: cuda>=13.0

The previous Dockerfile used nvidia/cuda:13.0.0-devel-ubuntu24.04 which attempted to manually install cuDNN 9, but Runpod requires CUDA 13.0+ with proper cuDNN integration.

Solution

Updated Dockerfile.runpod to use the official NVIDIA CUDA 13.0.1 base image with cuDNN 9 pre-installed:

Key Changes

Base Image Update
- Before: FROM nvidia/cuda:13.0.0-devel-ubuntu24.04
- After: FROM nvidia/cuda:13.0.1-cudnn-devel-ubuntu24.04
- Benefit: cuDNN 9 pre-installed, no manual installation required
Removed Manual cuDNN Installation
- Removed apt-get installation of libcudnn9-cuda-13
- cuDNN 9 (version 9.13.0+) is included in the base image
Updated Documentation
- Updated header comments to reflect CUDA 13.0.1 + cuDNN 9
- Image size corrected: ~4.3GB (down from 8.4GB estimate)
- Build time: 2-3 minutes
- Updated GPU compatibility notes for CUDA 13.x driver requirements
Library Dependencies Updated
- libcudnn.so.8 → libcudnn.so.9
- All CUDA 12.2 references → CUDA 13.0.1
- Added minimum driver requirement: r580 or newer
