ibacm - 44.0-2 main

The IB ACM implements and provides a framework for name, address, and
route (path) resolution services over InfiniBand.
It is intended to address connection setup scalability issues running
MPI applications on large clusters. The IB ACM provides information
needed to establish a connection, but does not implement the CM protocol.
A primary user of the ibacm service is the librdmacm library.
