Servers with multiple network cards

You can run eXtreme Scale processes on a server that has more than one network card.

If a server or client is running on a server that contains more than one network card, then specify the network port and host name in the eXtreme Scale configuration to bind to a specified card. If this configuration is not specified, then the eXtreme Scale runtime will automatically choose one, which may result in connection failures or slower performance.

For catalog or container servers, set the listener host and listener port in one of the following ways:

For clients, you cannot use the command line, and must use client properties.
