-Assistant for InfiniBand Communication Management (IB ACM)
-
-Note: The IB ACM should be considered experimental.
-
-
-Overview
---------
-The IB ACM package implements and provides a framework for experimental name,
-address, and route 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.
-
-The librdmacm can invoke IB ACM services when built using the --with-ib_acm
-option.  The IB ACM services tie in under the rdma_resolve_addr,
-rdma_resolve_route, and rdma_getaddrinfo routines.  For maximum benefit,
-the rdma_getaddrinfo routine should be used, however existing applications
-should still see significant connection scaling benefits using the calls
-available in librdmacm 1.0.11 and previous releases.
-
-The IB ACM is focused on being scalable and efficient.  The current
-implementation limits network traffic, SA interactions, and centralized
-services.  ACM supports multiple resolution protocols in order to handle
-different fabric topologies.
-
-This release is limited in its handling of dynamic changes.
-
-The IB ACM package is comprised of two components: the ib_acm service
-and a test/configuration utility - ib_acme.  Both are userspace components
-and are available for Linux and Windows.  Additional details are given below.
-
-
-Quick Start Guide
------------------
-1. Prerequisites: libibverbs and libibumad must be installed.
-   The IB stack should be running with IPoIB configured.
-   These steps assume that the user has administrative privileges.
-2. Install the IB ACM package
-   This installs ib_acm, and ib_acme.
-3. Run ib_acme -A -O
-   This will generate IB ACM address and options configuration files.
-   (acm_addr.cfg and acm_opts.cfg)
-4. Run ib_acm and leave running.
-   ib_acm will eventually be converted to a service/daemon, but for now
-   is a userspace application.  Because ib_acm uses the libibumad
-   interfaces, it should be run with administrative privileges.
-5. Optionally, run ib_acme -s <source_ip> -d <dest_ip> -v
-   This will verify that the ib_acm service is running.
-5. Install librdmacm.
-   The librdmacm will automatically use the ib_acm service.
-   On failures, the librdmacm will fall back to normal resolution.
-
-
-Details
--------
-ib_acme:
-The ib_acme program serves a dual role.  It acts as a utility to test
-ib_acm operation and help verify if the ib_acm service and selected
-protocol is usable for a given cluster configuration.   Additionally,
-it automatically generates ib_acm configuration files to assist with
-or eliminate manual setup.
-
-
-acm configuration files:
-The ib_acm service relies on two configuration files.
-
-The acm_addr.cfg file contains name and address mappings for each IB
-<device, port, pkey> endpoint.  Although the names in the acm_addr.cfg
-file can be anything, ib_acme maps the host name and IP addresses to
-the IB endpoints.
-
-The acm_opts.cfg file provides a set of configurable options for the
-ib_acm service, such as timeout, number of retries, logging level, etc.
-ib_acme generates the acm_opts.cfg file using static information.  A
-future enhancement would adjust options based on the current system
-and cluster size. 
-
-
-ib_acm:
-The ib_acm service is responsible for resolving names and addresses to
-InfiniBand path information and caching such data.  It is currently
-implemented as an executable application, but is a conceptual service
-or daemon that should execute with administrative privileges.
-
-The ib_acm implements a client interface over TCP sockets, which is
-abstracted by the librdmacm library.  One or more back-end protocols are
-used by the ib_acm service to satisfy user requests.  Although the
-ib_acm supports standard SA path record queries on the back-end, it
-provides an experimental multicast resolution protocol in hope of
-achieving greater scalability.  The latter is not usable on all fabric
-topologies, specifically ones that may not have reversible paths.
-Users should use the ib_acme utility to verify that multicast protocol
-is usable before running other applications.
-
-Conceptually, the ib_acm service implements an ARP like protocol and either
-uses IB multicast records to construct path record data or queries the
-SA directly, depending on the selected route protocol.  By default, the
-ib_acm services uses and caches SA path record queries.
-
-Specifically, all IB endpoints join a number of multicast groups.
-Multicast groups differ based on rates, mtu, sl, etc., and are prioritized.
-All participating endpoints must be able to communicate on the lowest
-priority multicast group.  The ib_acm assigns one or more names/addresses
-to each IB endpoint using the acm_addr.cfg file.  Clients provide source
-and destination names or addresses as input to the service, and receive
-as output path record data.
-
-The service maps a client's source name/address to a local IB endpoint.
-If a client does not provide a source address, then the ib_acm service
-will select one based on the destination and local routing tables.  If the
-destination name/address is not cached locally, it sends a multicast
-request out on the lowest priority multicast group on the local endpoint.
-The request carries a list of multicast groups that the sender can use.
-The recipient of the request selects the highest priority multicast group
-that it can use as well and returns that information directly to the sender.
-The request data is cached by all endpoints that receive the multicast
-request message.  The source endpoint also caches the response and uses
-the multicast group that was selected to construct or obtain path record
-data, which is returned to the client.
-
-The current implementation of the IB ACM has several additional restrictions:
-- The ib_acm is limited in its handling of dynamic changes;
-  the ib_acm must be stopped and restarted if a cluster is reconfigured.
-- Cached data does not timed out and is only updated if a new resolution
-  request is received from a different QPN than a cached request.
-- Support for IPv6 has not been verified.
-- The number of addresses that can be assigned to a single endpoint is
-  limited to 4.
-- The number of multicast groups that an endpoint can support is limited to 2.
