>   I have fixed some bugs in the code. Now, with the upcoming 
> latest release (1.0.7 - available in couple of weeks - or you 
> could extract the latest source from svn) you should be able 
> to set the environment variable, 
> SMPD_OPTION_NO_DYNAMIC_HOSTS, to 1 and inform smpd daemons 
> not to update (add dynamic hosts) the smpd config file. Since 
> multiple smpd daemons don't update the config file (with the 
> prev env var set) you don't need different conf files for the 
> daemons (all daemons can share the .smpd config file in your 
> shared home directory)
>   So this is what you would have to do,
> 
> 1) Set the environment variable SMPD_OPTION_NO_DYNAMIC_HOSTS 
> to 1 (In all the nodes).
> 2) Create .smpd file in your HOME directory (possibly shared 
> across nodes) with the passphrase (The only line in the smpd 
> config file should be the passphrase, phrase=myphrase. Delete 
> any other lines in the config file)
> 3) Start smpd, smpd -s, in each node (Note that you no longer 
> need to specify the smpd config file as an option here) .
> 4) Run mpiexec, mpiexec -n 2 -machinefile mf.txt cpi  (Note 
> that you no longer need to specify the smpd config file as an 
> option here) .
