| .SH NAME |
| ibacm \- InfiniBand communication management assistant |
| .SH SYNOPSIS |
| .B "#include <infiniband/acm.h>" |
| .SH "DESCRIPTION" |
| Used to resolve remote endpoint information before establishing communications |
| over InfiniBand. |
| .SH "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. |
| .P |
| 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. |
| .P |
| Client interactions with the ibacm service are done over sockets through |
| a standard TCP connection. The librdmacm abstracts this interaction. |
| .SH "RETURN CODES" |
| .IP "== 0" |
| success |
| .IP "!= 0" |
| error |
