pocx_plotter

High-performance plot file generator with CPU and GPU acceleration support.

Features

• Multi-Threaded CPU: Efficient CPU plotting with thread scheduling
• GPU Acceleration: Optional OpenCL support for faster plotting
• SIMD Optimizations: Leverages pocx_hashlib SIMD implementations
• Memory Management: Page-aligned buffers and efficient memory usage
• Compression Support: POW scaling via compression parameter
• Progress Monitoring: Real-time plotting progress with indicatif
• Resume Support: Continue interrupted plotting with seed parameter

Quick Start

# CPU plotting (10 warps = ~10GB)
pocx_plotter -i <your_address> -p /path/to/plots -w 10

# GPU plotting with OpenCL  
pocx_plotter -i <your_address> -p /path/to/plots -w 10 -g 0:0

# With compression (2^4 scaling)
pocx_plotter -i <your_address> -p /path/to/plots -w 10 -x 4

# Resume plotting with seed
pocx_plotter -i <your_address> -p /path/to/plots -w 10 -s <seed_value> -n 1

Build

# CPU-only build
cargo build --release -p pocx_plotter

# With OpenCL support
cargo build --release -p pocx_plotter --features opencl

# List OpenCL devices
./target/release/pocx_plotter -o

Command Line Options

• -i, --id <address> - Your PoC mining address (required)

• -w, --warps <warps> - Number of warps to plot (1 warp = 1 GiB)
• -n, --num <number> - Number of files to plot (default: 1)
• -x, --compression <level> - POW scaling factor (default: 1)
• -s, --seed <seed> - Seed to resume unfinished plot
• -c, --cpu <threads> - CPU threads to use
• -g, --gpu <platform:device:cores> - GPU configuration for plotting
• -m, --mem <memory> - Memory limit when plotting multiple disks
• -b, --bench - Run in benchmark mode
• -o, --opencl - Display OpenCL platforms and devices

OpenCL GPU Plotting

# List available OpenCL devices
pocx_plotter -o

# Use specific GPU (platform 0, device 0)
pocx_plotter -i <address> -p /plots -w 100 -g 0:0

# Multiple GPUs with custom core count
pocx_plotter -i <address> -p /plots -w 100 -g 0:0:1024 -g 0:1:1024
