fedora 12 MPICH 安装问题

icebergs

mpi已经安装完：运行如下
[ice@icebergs ~]$ mpd &
[1] 7478
[ice@icebergs ~]$ mpdtrace
icebergs
[ice@icebergs ~]$ mpdboot
/home/ice/mpich2-install/bin/mpdboot:56: DeprecationWarning: The popen2 module is deprecated.  Use the subprocess module.
  from popen2   import Popen4, Popen3, popen2
mpdboot_icebergs (handle_mpd_output 393): failed to handshake with mpd on icebergs; recvd output={}

[1]+  Done                    mpd
使用调试状态运行，出现如下结果：
[ice@icebergs ~]$  mpdboot  --chkup -s -v
/home/ice/mpich2-install/bin/mpdboot:56: DeprecationWarning: The popen2 module is deprecated.  Use the subprocess module.
  from popen2   import Popen4, Popen3, popen2
there are 1 hosts up (counting local)
running mpdallexit on icebergs
LAUNCHED mpd on icebergs  via  
mpdboot_icebergs (handle_mpd_output 393): failed to handshake with mpd on icebergs; recvd output={}
使用mpdcheck -s和mpdcheck -c * *调试单节点也没问题，.mpd.conf文件也配置正确，ssh本机无密码也可以。
PS:我测试的是本机单节点，我的hostname是icebergs。
