+   http://simgrid.org/tutorials/simgrid-energy-101.pdf
+
+ * Model-Checker progresses toward production use:
+   - More robust (now runs in a separate process).
+   - More efficient (with snapshots' memory compaction).
+   - More usable (execution paths replayed out of MC)
+   http://simgrid.org/tutorials/simgrid-mc-101.pdf
+
+ * SMPI improvements:
+   - Better standard coverage  - SMP-aware collectives
+   - InfiniBand model          - Early support for RMA
+   - Replay: Dynamic selector  - MVAPICH2 selector
