NAME

6       ibacm - InfiniBand communication management assistant
7

SYNOPSIS

9       #include <infiniband/acm.h>
10

DESCRIPTION

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

NOTES

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.
20
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.
