+         * 
+         * This package is created for the thermal-aware scheduling policies designed in CoolEmAll (www.cooemall.eu).
+         * Details of these policies and experimental results can be found in deliverable D4.6 on the project website.
+         * 
+         * The setting and the temperature estimation is for a CoolEmAll RECS with 18 nodes and the following layout:
+         *     | 10   01 | 
+         *     | 11       02 |
+         *     | 12       03 |
+         *     | 13       04 |
+         *     | 14       05 |

+         *     | 16       07 |
+         *     | 17       08 |
+         *     | 18       09 |
+         * where node i and i+9 share the same outlet and inlet for i = 1..9.
+         * 
+         * The thermal-aware scheduling plugins (Coolest, MaxTempOpt and TempIncrOpt) are implemented in the version 
+         * of the simulator dated 2014 March. In this version, 
+         * (1). The power estimation of a node is guaranteed to be correct upon each invocation of the scheduler.
+         * (2). The temperature, however, may not be up to date, so one should always derive temperature from power.
+         * (3). If each invocation of the scheduler schedules several jobs, the power (and temperature) is not 
+         *              updated between job assignments. So one should always keep track of the power (and temperature)
+         *              changes locally in this case.
