+ * Privatization is now activated by default in smpirun
+   You can turn it off with -no-privatize if something goes wrong.

  * Call-location tracing for SMPI.
    You can add the exact location (filename / linenumber) of an MPI call to 
    your trace files and slow down or speed up the simulation between two
