[MPICH] mpich2-1.05 on the intel Mac OS X

[Jiming Jin]

Hi Everyone,
  I just installed MPICH2-1.0.5p3 on my Pro Mac using the gfortran  
compiler (Mac OS X with intel chips, 4 processors total).  I did  
'make testing', and I get a message saying "No Errors".
I assume the installation was successful. I started mpd on this  
computer, did several other tests and everything looked well.
I start to run my model (it is a climate model (WRF)) with 'mpiexec - 
n 4 wrf.exe and I  only see one processor is running with more than  
90% cpu, and other three processors are sleeping(with 0% cpu). When I  
put the run to the background (Ctr-Z), I get the following error  
messages:


pmpiexec_storm.lbl.gov: mpd_uncaught_except_tb handling:
   exceptions.IOError: [Errno 9] Bad file descriptor
     /usr/local/mpich/bin/mpiexec  1041  handle_stdin_input
         sys.stdin.flush()  # probably does nothing
     /usr/local/mpich/bin/mpdlib.py  743  handle_active_streams
         handler(stream,*args)
     /usr/local/mpich/bin/mpiexec  500  mpiexec
         rv = streamHandler.handle_active_streams(timeout=1.0)
     /usr/local/mpich/bin/mpiexec  1399  ?
         mpiexec()

Could someone give me suggestions on this problem? Thanks.

I compiled my model using the following options:
