Is the job completing? Usually this message appears because mpirun
terminates before everything else does. Only concern I have is that
the process that issued your example message is an application
process, but I'm assuming it was running local to mpirun - yes?
No the job is not completin
I've run into a problem upgrading from 1.4.3 to 1.4.4 or 1.4.5
With 1.4.4 and 1.4.5, I'm getting error messages like
[[59597,1],0] routed:binomial: Connection to lifeline [[59597,0],0] lost
The error does not occur if I restrict the host list to localhost.
Basic tests like 'mpirun hello_c'
I've put together a simple system for running OMPI on EC2 (Amazon's cloud
computing service). If you're interested, see

Yes, after I wrote yesterday, I realized there's no need to have the
'source' wide open. Glad to know that

That's certainly a good idea. Eventually I hope to

That makes sense. Do you know how open
I've run into a problem involving accessing a remote host via a router
and I think need to understand how opmpi determines ip addresses. If
there's anything posted on this subject, please point me to it.
Here's the problem:
I've installed opmpi (1.4.3) on a remote system (an Amazon ec2
instance)

^ In that case, where and how does OMPI call ssh?
ssh has a '-i' option which can be used to specify the id_rsa file.

I need to find a way of controlling the rsa key used when open-mpi uses
ssh to access hosts. By default, ssh uses the
~/.ssh/id_rsa
However, I need to set the key used without messing around with users'
.ssh directories. It appears that in a default installation of
open-mpi, ~/.ssh is specf

Are there any other environmental variables that need to be set?
I'd appreciate any suggestions about this.
