IBACM(7) IB ACM User Guide IBACM(7)NAMEibacm - InfiniBand communication management assistant
SYNOPSIS
#include <infiniband/ib_acm.h>
DESCRIPTION
Used to resolve remote endpoint information before establishing commu‐
nications 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 inter‐
action.
