I am not sure what I am missing here?<br>
<br> [root@master bin]# mpiexec -genv QPL_LICENSE 4705 -n 3 a.out<br>
<br>
mpiexec_master.jtalla.kfu: mpd_uncaught_except_tb handling:<br>
exceptions.KeyError: 'cmd'<br>
/opt/mpich2/gnu/bin/mpiexec 259 mpiexec<br>
elif msg['cmd'] != 'response_get_mpdrun_values':<br>
/opt/mpich2/gnu/bin/mpiexec 1446 ?<br>
mpiexec<br><br>so I think it is an MPD issue.<br>
