NAME         top

       ibacm - InfiniBand communication management assistant

SYNOPSIS         top

       #include <infiniband/acm.h>

DESCRIPTION         top

       Used to resolve remote endpoint information before establishing
       communications over InfiniBand.

NOTES         top

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

       The IB ACM provides information needed to establish a connection, but
       does not implement the communication management protocol.  It
       provides services similar to rdma_getaddrinfo, rdma_resolve_addr, and
       rdma_resolve_route using IB multicast.  The IB ACM does not require
       IPoIB or use standard naming services, such as DNS, and limits
       network communication, especially with the IB SA.  The ib_acme
       utility assists in verifying what options of the ibacm service may be
       usable for the current fabric topology.

       Client interactions with the ibacm service are done over sockets
       through a standard TCP connection.  The librdmacm abstracts this
       interaction.
