Hi!

I regularly run jobs like that on 1.3.1 - it has no desire to use ssh to
start anything. On a local host such as this command uses, all mpiexec
does is fork/exec the procs.
That sounds strange. I'm just going back and forth between OpenMPI 1.2.9
and OpenMPI 1.3.1 by using make uninstall/make install, and I can always
reproduce the behavior.
It sounds like something strange is going on in your environment that
makes OMPI think it is launching on a remote host. Most likely cause is
something in your Ethernet configuration. Can you send us the output of
ifconfig (or whatever your equivalent is)?
Ok, here is some information on my system:
* Kubuntu 9.04 (Jaunty) alpha 6
* Core Duo CPU
* I have compiled both OpenMPI versions (1.2.9 and 1.3.1) myself, using
configure --prefix=$HOME/software --enable-shared --enable-static
Output of some ifconfig:
