+ * Scenario:

+ * - Create two communication tasks: 1GB and 100MB
+ * - Schedule them concurrently on the two hosts of the platform
+ * The two communications occur simultaneously. They share the network for the
+ * duration of the shortest one, then the longest one has the full bandwidth.
+ * Simulated time should be:
+ * 1e8/(1/2*1.25e8) + 9e8/1.25e8) + 1e-4 = 8.8001 seconds
