SimGrid (3.3-cvs) unstable; urgency=low
Introduce the SIMIX module: factorize code between MSG and GRAS.
- Until now, GRAS were using MSG as an interface to SURF. It was

+ Until now, GRAS were using MSG as an interface to SURF. It was
quite difficult because both interface have several differences
(MSG channels vs GRAS sockets were the most notable point).
- This also opens the gate to SMPI, which should occur soon.
- DO NOT MIX 3.2 RESULTS WITH 3.3 ONES: Simix may changes simulations
+ This also opens the gate to SMPI (which should occur soon) and speed
+ up simulations by to 40% (even if it were not the main goal).

The point is that events occuring at the exact same timestamp are
- not scheduled in the same order with the old and new version. This
- may be enough to completely change the execution of simulations.
- Sorry for the inconvenience.

+ GRAS:
+ * Convert the PIDs from long int to int to match the MSG ones (and
+ linux ones too)
- OVERALL CHANGES:
+ XBT:
* Make the backtrace of exceptions more human readable [Mt]
