Protocol Attribute

This column identifies the communication protocol used by the interface. The scirsm interface employs the RSM (Remote Shared Memory) protocol. The others in the default list all use TCP (Transmission Control Protocol).

If you add a network interface of a type not represented in the hpc.conf template, you will need to specify the type of protocol the new interface uses.
