+* faire un autre thread pour les envois d'infos
+ -> c'est stupide d'attendre la fin des calcules s'il y en a beaucoup
+ surtout en bookkeeping...
+
+* review receive with timeout.
+
* verify bookkeeping version.
-* add a variant to (not) change neighbor load information at send.
+* add several metrics
+ - message exchanges : number/volume of sent/received data/ctrl messages
-* implement loba_* algorithms (start with some trivial one)
+* add options -j/-J : minimum number of iterations?
-* add some statistics about load (im)balance at the end of the simulation?
+* add a variant to (not) change neighbor load information at send?
+
+* implement loba_* algorithms (start with some trivial one)
* for automatic process topology,
-> implement some random initial distribution of load
