Subject: [OMPI users] Open MPI v1.4 cant find default hostfile
From: Mario Ogrizek (mario.guardian_at_[hidden])

Hi, I've been redirected from PTP mailing list, so i hope i will find help
This is the problem:

I am running Open MPI v1.4 on OS X SL.
When trying to run a simple hello world program, i get this error message,
that aborts the process:

Open RTE was unable to open the hostfile:
Check to make sure the path and filename are correct.

Ofcourse, i doublechecked the file exists at that path.
It was used normally with old version of Open MPI,1.2 (which came with the
OS). And i can still run hello world normally with v1.2.

Also in PTP, resouce manager v1.4 doesnt recognize that hostfile, and
specified nodes do not exist.

Thank's in advance!
