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
