+ SMPI:
+ * Massive internal cleanups:
+ - Store internal structures on processes instead of hosts (allows
+ to have more than one process per host, in addition of being more
+ logical)
+ - Cleanup the initialization/finalization process
+ - Kill a whole bunch of unneeded synchronization:
+ processes run in exclusive manner within the simulator
+ - Move queues from global tables to process data fields
+ * Improve smpirun:
+ - now accept -platform and -hostfile arguments
+ - Pass the right rank value to processes according on hostfile
Build Chain:
* Do not require doxygen in maintainer mode
