[mpich2-dev] configfile vs machinefile

[Thomas Wharton]

Hello,

I have three questions regarding configfiles/machinefiles used with
mpiexec.

1) What is the difference between a configfile and a machinefile?

2) Are they, or can they be, used in conjunction?  (Or should they be used
in conjunction?)

3) Does a configfile provide everything that a machinefile does?  (Note:
>From what I've read, it seems like the options you can set in configfile
are a superset of the machinefile -- but I am not certain about this).

Many Thanks,
Thomas Wharton
