      Machine: ranges are now used instead of sets. · 4567c6dd
      Millian Poquet authored
      This modification impacts all parts of Batsim in which machines were involved.
      The protocol has also been updated to allow the scheduler to send machine ranges
      in its allocations. The previous syntax is still supported. Now, each comma-separated
      value can either be 1 machineID or a range of machineIDs (syntax: machineIDa-machineIDb
      to represent the closed interval [machineIDa, machineIDb]).
      Please note that Batsim has been only been tested with old schedulers (that do not
      support the new protocol syntax).

      Implementation of the energy mechanism. · f083f79d
      Millian Poquet authored
      If the energy is enabled (by setting the -p run option), the platform is assumed to contain energy information.
      Such information is read by SimGrid itself but another ones, such as the 'sleep_pstates' property, are read by Batsim.
      A lot of assertions has been put in the reading of the platform file which will help generating energy platforms.
      An example of such a platform can be found in platforms/energy_platform.xml. This platform follows the same rules
      that those of SimGrid energy platforms but assures pstate coherency via the 'sleep_pstates' property: it says
      which pstates are sleep pstates and which pstates are its associated virtual pstates (for switching ON and OFF
      each pstate). More information can be found in the file 'platforms/energy_platform.xml'
      The scheduler can now send messages of the form TIMESTAMP:P:M=S where M is a machineID and S the asked new pstate
      for machineID. Batsim does the stuff to simulate the time & energy consumptions of the switchON/OFF (if any, you
      can also switch from one computation state to another). Once the pstate of a machine has changed, Batsim sends
      it on the socket with messages of the form TIMESTAMP:p:M=S where M is a machineID and S the new pstate of the
      corresponding machine (note the lowercase 'p' instead of an uppercase 'P').
      To simulate the energy & time costs of the switch ON/OFF, the exact same mechanism as the one presented in
      SimGrid energy 1O1 is used: computing 1 flop on virtual pstates whose computational power and power
      consumption met our time and energy consumptions needs.
