So the IP world analog would be: fd = socket(AF_INET,SOCK_DGRAM); connect(fd,'Some Unicast Address'); setsockopt(fd,IP_MULITCAST_ADD_MEMBERSHIP,'Some Multicast Address'); sendto(fd,...,'Some Multicast Address'); ? I think that is still OK. The routines still bind the rdma cm_id to the devices via rdma_translate_ip pretty much like they did before. There is no support for Linux IP multicast routing though..
