=> The current GM API (1.3.1) does not seem to provide function
=> calls for multicasting. The gm_send_with_callback() function
=> provides for only point-to-point communication.
=> Could someone let me know if there is any hidden function
=> inside GM that supports multicasting or whether there has
=> been any implementation of this feature elsewhere?
=> If not, would an implementation of this feature require

The gm_ethernet_send function supported in the kernel does
provide datagram ("unreliable") broadcast. The normal gm API
does not support multicast or broadcast.
Our old myriAPI MCP did support multicast, but very few folks
needed it. As mentioednin another follow-up, there are several MCPs
that support multicast.
