Thomas Preud'homme ad804e4a5a [comm tech bench] 1 gnuplot per graph 
- Refactor parsing.sh to have one gnuplot file per graph
- Change the set style data from lines to linespoints
- Add one title per series of point (one for each every) in dat headers

Thomas Preud'homme c98db4b4ba commtech: do_calc() return a void ** 
This respect what we claim to send to the send() function and allow to
reduce the FAKE_NURSERY_START. Thus we are sure gcc won't optimize the
second part of the if in include/jikes_barrier_comm.h
 2009-06-30 22:35:11 +02:00
Thomas Preud'homme 7bfc46db78 commtech: Delete pages free 
Pages cannots be freed as fast as they are allocated, so this whole
mecanism can only delay the kernel panic. It's wiser to exit badly if
too much memory is consumed
