I'm having trouble understanding your note, so perhaps I am getting this wrong. Let's see if I can figure out what you said:

* your perl command fails with "no route to host" - but I don't see any host in your cmd. Maybe I'm just missing something.

* you tried running a couple of "mpirun", but the mpirun command wasn't recognized? Is that correct?

* you then ran mpiblast and it sounds like it successfully started the processes, but then one aborted? Was there an error message beyond just the -1 return status?
