NAME

       ibacm - InfiniBand communication management assistant

SYNOPSIS

       #include <infiniband/acm.h>

DESCRIPTION

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

NOTES

       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.

RETURN CODES

       == 0   success

       != 0   error
