- <!-- That may be seen as a misuse of the pstate mechanism and crude hack, but this is efficient: we can do what
- we want without too much burden, and since the whole intelligence is at user level, we do control the model.
-
- The same could be done to encode the time and energy to switch between pstates. These times seem negligible

- * 3: booting up was measured to take 150s and 18000J.
- So we create a pstate with 1 flop/150 s so that the application burns 1 flop in that virtual pstate to
- simulate a boot.
- Multiply everything by 1000 or whatever if this trick is too painful to you, that's the same by the end.
- The energy consumption is 18000/150=120W
- * 4: shutting down was measured to take 7 s and 770 J
-
- Please note that we tried to put sensible values in this file but you should still take them with a grain of salt.

+/* This is an example of how the bootup and shutdown periods can be modeled
+ * with SimGrid, takes both the time and overall consumption into account.
+ *
+ * The main idea is to augment the platform description to declare fake
+ * pstate that represent these states. The CPU speed of these state is zero
+ * (the CPU delivers 0 flop per second when booting) while the energy
+ * consumption is the one measured on average on the modeled machine.
+ *
+ * When you want to bootup the machine, you set it into the pstate encoding
+ * the boot (3 in this example), and leave it so for the right time using a
+ * sleep_for(). During that time no other execution can progress since the
+ * resource speed is set at 0 flop/s in this fake pstate. Once this is over,
+ * the boot is done and we switch back to the regular pstate. Conversely,
+ * the fake pstate 4 is used to encode the shutdown delay.
+ *
+ * Some people don't like the idea to add fake pstates for the boot time, and
+ * would like SimGrid to provide a "cleaner" model for that. But the "right"
+ * model depends on the study you want to conduct. If you want to study the
+ * instantaneous consumption of a rebooting data center, the model used here
+ * is not enough since it considers only the average consumption over the boot,
+ * while the instantaneous consumption changes dramatically. Conversely, a
+ * model taking the instantaneous changes into account will be very difficult
+ * to instantiate correctly (which values will you use?), so it's not adapted
+ * to most studies. At least, fake pstates allow you to do exactly what you
+ * need for your very study.
