Subject: Re: [OMPI users] MPI_Lookup_name
From: Ralph Castain (rhc_at_[hidden])

It works fine, but you didn't specify the ompi-server uri correctly. On the
mpirun cmd line, you needed to specify it as "file:test" so we know that it
is a filename and not something else. Here is the mpirun help output:

"Specify the URI of the Open MPI server, or the name of the file (specified
as file:filename) that contains that info"

As given below, we attempted to use a uri of "test", which provides a
meaningless contact point. I'll try to provide a more informative error
message, though, as the current one is rather useless, I must admit. :-/

Thanks
Ralph
