-* Try to optimize communications when bookkeeping.
- Add a 'credit' counter for each neighbor.
- Do not send more real_load than (debt - credit).
+* Change simulator to use discrete tasks.
+ Each task must then be iterated a minimum of times.
+ At least two strategies to balance the tasks:
+ (i) send the tasks that have the most count of iterations;
+ (ii) send the tasks that have the least count of iterations.
* Support heterogeneous platforms?
