12 Used to resolve remote endpoint information before establishing commu‐
13 nications over InfiniBand.

16 Th IB ACM provides scalable address and route resolution services over
17 InfiniBand. It resolves system network names and IP addresses to
18 InfiniBand path record data using efficient mechanisms, including
19 caching of data.

21 The IB ACM provides information needed to establish a connection, but
22 does not implement the communication management protocol. It provides
23 services similar to rdma_getaddrinfo, rdma_resolve_addr, and
24 rdma_resolve_route using IB multicast. The IB ACM does not require
25 IPoIB or use standard naming services, such as DNS, and limits network
26 communication, especially with the IB SA. The ib_acme utility assists
27 in verifying what options of the ibacm service may be usable for the
28 current fabric topology.
29
30 Client interactions with the ibacm service are done over sockets
31 through a standard TCP connection. The librdmacm abstracts this inter‐
32 action.
