Subject: Re: [OMPI users] Application Context and OpenMPI 1.2.4

Hi Pat

A friendly elf forwarded this to me, so please be sure to explicitly include
me on any reply.

Was that the only error message you received? I would have expected a trail
of "error_log" outputs that would help me understand where this came from.
If not, I can give you some debug flags to set once I know the environment.

Usually, that error indicates a mismatch between the backend daemon and
mpirun - one is from 1.2.4, for example, while another was from some other
build - but it is hard to tell without seeing some more error output.

I assume this is using ssh as a launch environment?
