[mpich2-dev] Hydra 1.4 configfile usage (or bug?)

[Cody R. Brown]

With MPICH2 1.3.1, I would use the -configfile option like below with
a simple helloWorld example:
  mpiexec -configfile appfile hello

The contents of the appfile could be this to spawn 12 processes of the
hello executable:
  [cody at cyclops helloworld]$ more appfile
   -n 10 hello
   -n 2 hello


Using Hydra 1.4, the configfile option no longer seems to be
functioning correctly. It attempts to execute the config file (appfile
in this case), and you get permission denied errors. I notice the
changes in config_fn function in "ui/mpich/utils.c". Is this a bug, or
was the syntax of the configfile contents change to a new format?

Thanks,
