-The Ping node can be configured to send messages at a configured rate. The Pong node takes these ping messages and replies each of them. Before sending the reply, it can be configured to burn cycles (thereby varying the processor load) to simulate some message processing. We provide bash scripts to test intra-process and inter-process communication scenarios, wherein the nodes are co-located either in one process or two processes, respectively. These scripts also vary the message rates and processor loads. After each run, the Ping node outputs the measured the throughput of real-time and best effort messages.
