Re: [OMPI users] running open mpi on ubuntu 9.04
It doesn't matter - 1.3 isn't going to launch another daemon on the local node. The problem here is that OMPI isn't recognizing your local host as being "local" - i.e., it thinks that the host mpirun is executing on is somehow not the the local host. This has come up before with ubuntu - you might search the user mailing list for "ubuntu" to see earlier threads on this issue. I forget the final solution, but those earlier threads will explain what needs to be done. I'm afraid this is something quite specific to ubuntu.

Here is the output: erin@erin-laptop:~$ mpirun -np 2 a.out ssh: connect to host erin-laptop port 22: Connection refused -- A daemon (pid 11854) died unexpectedly with status 255 while attempting to launch so we are aborting. There may be more information reported by the environment (see above). This may be because the daemon was unable to find all the needed shared libraries on the remote node. You may set your LD_LIBRARY_PATH to have the location of the shared libraries on the remote nodes and this will automatically be forwarded to the remote nodes. -- -- mpirun noticed that the job aborted, but has no info as to the process that caused that situation. -- mpirun: clean termination accomplished erin@erin-laptop:~$ Any help would be much appreciated.
