Subject: Re: [OMPI users] Open RTE was unable to open the hostfile:

It really helps if you tell us *something* about the problem - like what version of OMPI you are using. :-/

At a guess, you are possibly using 1.6.x. If so, then you are missing your default hostfile. You can work around the problem by adding "--default-hostfile none" to the cmd line.
