+ * Scenario:
+ * - Create a no-op Init task
+ * - Create two communication tasks: 100MB and 1B
+ * - Schedule them concurrently on the two hosts of the platform
+ * The two communications occur simultaneously but one is so short that it has
+ * no impact on the other.
+ * Simulated time should be:
+ * 1e8/1.25e8 + 1e-4 = 0.8001 seconds
+ * This corresponds to paying latency once and having the full bandwidth for the
+ * big message.
