Should be doable if each process also sends its speed to its neighbors.
-* 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 options -f/-F: termination based on flops achieved?
* Reindent source code.
Mainly loba_{bulk,lln}.cpp.
