- * Scenario:
- * - A chain of tasks: t1 -> c1 -> t2 -> c2 -> t3 -> c3 -> t4 alternatively
- * scheduled across two workstations (Tremblay and Jupiter) connected by a
- * single link (link1)
- * - Make the characteristics of the resources change across time
- * Jupiter
- * [0.000000 -> 2.000000[ runs at half speed: 12500000
- * [2.000000 -> end[ runs at full speed: 25000000
- * Tremblay
- * [0.000000 -> 1.000000[ runs at half speed: 15000000
- * [1.000000 -> 4.000000[ runs at full speed: 25000000
- * [4.000000 -> 6.000000[ runs at half speed: 12500000
- * then loop back.
- * link1
- * [0.000000 -> 2.000000[ bandwidth = 125000000

- * [4.000000 -> 6.000000[ bandwidth = 31250000
- * then loop back.
- * - Adjust tasks' amounts to have comprehensive execution times
- * t1: 25000000 flops, should last 2 seconds
- * c1: 125000000 bytes, should last 1.0001 seconds
- * t2: 25000000 flops, should last 1 second
- * c2: 62500000 bytes, should last 1.0001 seconds
