Subject: Re: [OMPI users] Using hostfile with default hostfile
From: jody (jody.xha_at_[hidden])

Where is the option 'default-hostfile' described?
It does not appear in mpirun's man page (for v. 1.4.2)
and i couldn't find anything like that with googling.

Sounds strange, I suppose, but the idea is that the default hostfile can contain configuration info (#sockets, #cores/socket, etc.) that you might not want to have to put in every hostfile.
