ns-3-dce mpi

[jian ye ye]

Hi,

I run the ns-3-dce's mpi example ("mpirun -np 2 ./waf --run dce-mpi-udp"), and I got some erros. Sometimes successful, but sometimes failed. 

Some version information as bellow:

ubuntu: 12.04.

ns3: 3.24

dce: 3.19

I add "--enable-mpi" in "bakeconf.xml" before I run "bake.py download" and "bake.py build" to use mpi in dce. 

I got erros as bellow:

• Sometime the error is : 'build'  finished successfully. But the job could not stopped unless "ctrl + c".

• --------------------------------------------------------------------------
• mpirun has exited due to process rank 1 with PID 4609 on
• node test-virtual-machine exiting improperly. There are two reasons this could occur:
• 
  
• 1. this process did not call "init" before exiting, but others in
• the job did. This can cause a job to hang indefinitely while it waits
• for all processes to call "init". By rule, if one process calls "init",
• then ALL processes must call "init" prior to termination.
• 
  
• 2. this process called "init", but exited without calling "finalize".
• By rule, all processes that call "init" MUST call "finalize" prior to
• exiting or it will be considered an "abnormal termination"
• 
  
• This may have caused other processes in the application to be
• terminated by signals sent by mpirun (as reported here).
