-* segfault with ./loba cluster1000.xml -N64 -a fairstrategy
+* 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.

 
 

-    this is a deadlock occuring when:
-    - a process is in the finalize stage;
-    - all processes  but one are blocked on receive;
-    - the process that is still running owns all the remaining load,
-      and sends it all to the finalizing process, and then goes in
-      blocking receive.
-    The finalizing process receives the load, and blocks again,
-    waiting for a close message.
-    All processes are then blocked, and non-one is able to see that
-    there is no more load in the system!
+* Remove usage of opt::option_x in loba_besteffort.cpp and loba_2besteffort.cpp
+   Use -k instead (done).  Remove hack marked "FIXME" in opt::parse_args().

 
 

-* verify bookkeeping version.
+* Support heterogeneous platforms?
+   Not sure yet.
+   Should be doable if each process also sends its speed to its neighbors.

 
 

-* add several metrics
-  - flops (total, avg, stddev)
-  - message exchanges (number, volume)
+* Add options -j/-J: minimum number of iterations?

 
 

-* add options -j/-J : minimum number of iterations ?
+* Add options -f/-F: termination based on flops achieved?

 
 

-* add a variant to (not) change neighbor load information at send.
+* Choose a license before making the code public.
+   CeCILL-B?

 
 

-* implement loba_* algorithms (start with some trivial one)
+* Translate french parts in english (README, QUESTIONS, ALGORITHMS, ...)
+   Not urgent.

 
 

-* for automatic process topology,
-   -> implement some random initial distribution of load
+* Add synchronized mode?
+   No.

 
 

-* add synchronized mode
-
-* translate README file?
+* Add a variant to (not) change neighbor load information at send?
+   No.
