ACM is the "assistant to the communication manager".  It's both a lame reference to The Office, and I wanted to avoid calling it the 'CMA', since that commonly refers to the rdma_cm.  It does not impact the behavior of the CM itself.  In its simplest usage, it provides user space path record caching and is specifically targeted at supporting larger clusters.
