hello, 
I try to run mpich2 on amazon cloud today.I start 2 identical instances.
my OS (it's Ubuntu 9.04 Desktop)= Linux mymachine 2.6.16-xenU #1 SMP Mon May 28 03:41:49 SAST 2007 i686 GNU/Linux
 I did as installation guide until mpdboot and mpdcheck.i can ssh from both machines to each others without enter password.
mpdcheck on first machine
 >>$mpdcheck -s>>/root/mpich2-install/bin/mpdcheck:68: DeprecationWarning: The popen2 module is >>deprecated.  Use the subprocess module.>>  from  popen2   import Popen3>>server listening at INADDR_ANY on: firstmachine 49403
on second
 machine>> mpdcheck -c  domU-12-31-38-00-B1-06 49403>>/root/mpich2-install/bin/mpdcheck:68: DeprecationWarning: The popen2 module is >>deprecated.  Use the subprocess module.>>  from  popen2   import Popen3
Then i wait until it timeout.
So i give a try on mpdboot::::::::
when i mpdboot -n 1 i got this>>/root/mpich2-install/bin/mpdboot:56: DeprecationWarning: The popen2 module is >>deprecated.  Use the subprocess module.>> from popen2   import Popen4, Popen3, popen2
but it boot success.
when i mpdboot -n 2 -f mpd.hosts
>> mpdboot -n 2 -f mpd.hosts>>/root/mpich2-install/bin/mpdboot:56: DeprecationWarning: The popen2 module is
 >>deprecated.  Use the subprocess module.>> from popen2   import Popen4, Popen3, popen2>>
it freez at this stage. 

I rsearch in google and saw some ppl got similar problem. however, their problem related to python but my screen said nothing about python. In case, my python version is >>Python 2.6.2 (release26-maint, Apr 19 2009, 01:56:41)>>[GCC 4.3.3] on linux2
thx,Gra
