Use this information to update a compute node configuration.
When a compute node starts for the first time after you add or remove an internal device, you might receive a message that the configuration has changed. The Setup utility automatically starts so that you can save the new configuration settings. See Using the Setup utility for more information about the Setup utility.
Some devices have device drivers that you must install. See the documentation that comes with each device for information about installing device drivers.
The upper and lower compute nodes operate as symmetric multiprocessing (SMP) compute nodes, regardless of how many microprocessors are installed. For optimum performance, you must upgrade the operating system to support SMP. See Installing the operating system and your operating-system documentation for additional information.
