[mpich-discuss] mpdboot and hostsfile

[Kenin Coloma]

In the mpich2-1.2.1, mpdboot stopped working (upgraded from mpich2-1.1.1)
for a fairly simple host file

(on compute06)
mpdboot --totalnum=6 --ncpus=0

host file:
compute07
compute08
compute09
compute10
compute11

mpdboot will hang after trying to launch mpd on compute10

[kcoloma at compute06 ~]$
/rd_personalization08/kcoloma/mpich_install/bin/mpdboot --totalnum=6
--ncpus=0 --file=/home/kcoloma/mpiHosts.txt
--mpd=/rd_personalization08/kcoloma/mpich_install/bin/mpd --verbose

It will hang as long as --totalnum > 1.

mpdboot.py scripts are the same between the two versions of mpich, but the
mpd.py scripts changed to address ticket #905.  I've found that rolling back
to the mpich2-1.1.1p1 mpd.py, fixes the mpdboot issue I'm having.
