No. A single connection is used for two-way communication.

Cpu.java has the following line:
logger.info(block.getId() + ":" + getId() + " submitting " +
task.getIdentity());

This tells you when a job is sent to a worker.

If you want to know if a job is received by a worker, you need to enable
worker logging.

No. It refers to a block selecting a job for submission to a worker.
