[mpich-discuss] mpdboot hangs, but ...

[Benjamin Svetitsky]

Hello everybody,

I just upgraded from mpich2-1.0.8 to mpich2-1.2.1.  When I run

	mpdboot -n 4 -f /root/mpd.hosts

as root, the command just hangs until I hit ^C.  Nonetheless, it starts 
the daemons successfully and I can run MPI jobs as usual (so far).  A 
subsequent mpdallexit kills the saemons without complaint

Details:

I am running four Intel quad-cores under CentOS:
Linux version 2.6.18-164.6.1.el5.centos.plus
The file /root/mpd.hosts contains:
--
nodeA
nodeB
nodeC
nodeD
--
and I executed mpdboot on nodeC.
I compiled the MPICH2 source without any config options.
After mpdboot hangs for several minutes and I hit ^C, it responds:
--
Traceback (most recent call last):
   File "/usr/local/bin/mpdboot", line 476, in ?
     mpdboot()
   File "/usr/local/bin/mpdboot", line 347, in mpdboot
     handle_mpd_output(fd,fd2idx,hostsAndInfo)
   File "/usr/local/bin/mpdboot", line 385, in handle_mpd_output
     for line in fd.readlines():    # handle output from shells that 
echo stuff
KeyboardInterrupt
--
which may be irrelevant.

Thanks,
	Ben
