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

 
 

-* fix deadlock bug with  ./loba  cluster1000.xml -N26 -i2
+    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!

 
 

-* implement loba_* algorithms (start with some trivial one)
+* verify bookkeeping version.
+
+* add several metrics
+  - flops (total, avg, stddev)
+  - message exchanges (number, volume)

 
 

-* fix process::run (see inline comments)
+* add options -j/-J : minimum number of iterations ?

 
 

-* find a better 
+* add a variant to (not) change neighbor load information at send.

 
 

-* add some statistics about load (im)balance at the end of the simulation
+* implement loba_* algorithms (start with some trivial one)

 
 * for automatic process topology,
    -> implement some random initial distribution of load
 
 * add synchronized mode
