[mpich-discuss] Need some help getting mpich to work

Tue Nov 24 13:25:21 CST 2009

Your new "make testing" run is having problems with the MPI-I/O  
tests.  What sort of file system are you running this on?

As for the mpdboot problems, I'm not sure what is happening.  I would  
attempt to use the mpdcheck tool described in Appendix A of the  
Installer's Guide [1] to diagnose the problem.

You might also be having trouble because you are running part of your  
jobs on the cluster head node.  MPD's mpiexec will attempt to run 1  
process locally first unless passed the "-1" option.  Unfortunately  
there is no easy way to pass that option to the "make testing" process.

You can also try using hydra instead of MPD.  You should just be able  
to run "mpiexec.hydra -f /home/su/mpd.hosts -n 124 hostname | sort |  
uniq -c | sort -n" to sanity check that it works (you should get 31  
lines, each starting with 4).  If it does work for you, you can  
rebuild MPICH2 with "--enable-pm=hydra,mpd" to make hydra the default  
mpiexec.  Hydra will use the hostfile specified on the command line  
but it will also look at the file specified by the $HYDRA_HOST_FILE  
environment variable.  See [2] for more information on using hydra.
