How to capture a trace

1. Launch boards
2. Start the NTP server:

   $ /etc/init.d/ntp start

3. Optionally, free the core server port (example with port 12345):

   lsof -i tcp:12345 | grep LISTEN | awk '{print $2}' | xargs kill

4. Capture batches with:

   $ python3 replayer.py capture <SERVER_PORT> --trace-dir <TRACE_DIRECTORY>

How to replay a trace

1. Read the trace README.me file and copy its config.json file into the core server directory
2. Launch the core server
3. Run the trace emulator:

   $ python3 replayer.py replay <SERVER_PORT> --trace-dir <TRACE_DIRECTORY> --num-timeslots <NUMBER_OF_TIMESLOTS_IN_TRACE_DIR>
