oib 15427c96c0 chore: update file permissions to executable across repository 
- Change file mode from 644 to 755 for all project files
- Add chain_id parameter to get_balance RPC endpoint with default "ait-devnet"
- Rename Miner.extra_meta_data to extra_metadata for consistency

GPU Setup & Configuration

Configure and optimize your GPU setup for mining.

Prerequisites

Driver Installation

# Ubuntu/Debian
sudo apt install nvidia-driver-535

# Verify installation
nvidia-smi

CUDA Installation

# Download CUDA from NVIDIA
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-keyring_1.1-1_all.deb
sudo dpkg -i cuda-keyring_1.1-1_all.deb
sudo apt-get update
sudo apt-get install cuda-toolkit-12-3

Configuration

Miner Config

Create ~/.aitbc/miner.yaml:

gpu:
  type: v100
  count: 1
  cuda_devices: 0
  
performance:
  max_memory_percent: 90
  max_gpu_temp: 80
  power_limit: 250
  
jobs:
  max_concurrent: 4
  timeout_grace: 300

Environment Variables

export CUDA_VISIBLE_DEVICES=0
export NVIDIA_VISIBLE_DEVICES=all
export AITBC_GPU_MEMORY_LIMIT=0.9

Optimization

Memory Settings

performance:
  tensor_cores: true
  fp16: true  # Use half precision
  max_memory_percent: 90

Thermal Management

thermal:
  target_temp: 70
  max_temp: 85
  fan_curve:
    - temp: 50
      fan: 30
    - temp: 70
      fan: 60
    - temp: 85
      fan: 100

Troubleshooting

GPU Not Detected

# Check driver
nvidia-smi

# Check CUDA
nvcc --version

# Restart miner
aitbc miner restart

Temperature Issues

# Monitor temperature
nvidia-smi -l 1

# Check cooling
ipmitool sdr list | grep Temp
