Hammerhead Scheduler

Control Hammerhead's processing schedule to avoid resource conflicts with other intensive processes.

Build

mkdir build
cd build
cmake ..
cmake --build . --config Release

Usage

# Linux
./hammerhead_scheduler <src_ip>

# Windows
./Release/hammerhead_scheduler.exe <src_ip>

Parameters

  • src_ip: IP address of the device running Hammerhead

Examples

# Control Hammerhead processing schedule
# Use 127.0.0.1 if running on the same device as Hammerhead
./hammerhead_scheduler 127.0.0.1

# Use the network IP address if running on a different device
./hammerhead_scheduler 10.10.1.10

Configuration Required

In Hammerhead's master_config.ini file, set:

wait_for_scheduler = 1
wait_for_scheduler_timeout_ms = 5000

How It Works

  1. Hammerhead processes a frame
  2. Sends scheduler request with frame number
  3. Waits for scheduler reply before next frame
  4. Times out after configured milliseconds if no reply

Features

  • Native C++ performance for low-latency scheduling
  • Microsecond-level timing control
  • Prevents resource conflicts with other processes
  • Configurable timeout protection
  • Frame-by-frame processing control

Troubleshooting

  • No scheduler activity: Check that wait_for_scheduler = 1 in master_config.ini
  • Timeout errors: Adjust wait_for_scheduler_timeout_ms value
  • Connection issues: Verify network connectivity and IP address
