Open MPI is very aggressive about looking for and using any tcp
communications device it can find. In your case it will use both the
10.0.. network and the 192.168.. network at the same time. Open MPI
does not pay attention to the hosts names for the communications
channel. You want to do somet
Each of our servers has twin eth cards: 1GigE and 10GigE. How does
openmpi decide which card to use while sending messages on? One of the
cards is on a 10.0. IP address subnet whereas the other cards are on a
192.168 adress subnet. Can I select one or the other by specifying the

It does not happen every time; but pretty often. Any ideas what could
be wrong? The node seems pingable and I could log in suc
