Very nice ppt. Thanks. I have a question; On slide #8 you write: "Small latency hit if librdmacm compiled with ACM support, but service is not running". Is this latency hit on the fast path or control path? What do you refer as "small"? I guess this is for the cache miss cases. I expect the average to be better - this is the whole idea behind this idea, isn't it?

In any case, I completed the attached presentation for those interested in reading more about it. Simply put, IB ACM is a daemon that takes IP addresses and returns path records. Its main focus is on meeting the scalability requirements of MPI applications on large clusters. Work on IB ACM is ongoing.
