It works for me in both cases, provided I give the fully qualified host name for your first example. In other words, these work:
pn1180961:~/openmpi/trunk rhc$ mpirun -n 1 -host localhost printenv | grep LD [pn1180961.lanl.gov:22021] [0.0] test of print_name OLDPWD=/Users/rhc/openmpi LD_LIBRARY_PATH=/Users/rhc/openmpi/lib:/Users/rhc/lib:/opt/local/lib:/usr/lo cal/lib: pn1180961:~/openmpi/trunk rhc$ mpirun -n 1 -host pn1180961.lanl.gov printenv | grep LD [pn1180961.lanl.gov:22012] [0.0] test of print_name OLDPWD=/Users/rhc/openmpi LD_LIBRARY_PATH=/Users/rhc/openmpi/lib:/Users/rhc/lib:/opt/local/lib:/usr/lo cal/lib: But this will lockup: pn1180961:~/openmpi/trunk rhc$ mpirun -n 1 -host pn1180961 printenv | grep LD The reason is that the hostname in this last command doesn't match the hostname I get when I query my interfaces, so mpirun thinks it must be a remote host - and so we stick in ssh until that times out. Which could be quick on your machine, but takes awhile for me.
