Quoting r. Bryan O'Sullivan <bos@pathscale.com>: > The ipath_sma.c file supports a lightweight userspace subnet management > agent (SMA). This is used in deployments (such as HPC clusters) where > a full Infiniband protocol stack is not needed. Could you please explain why is this useful? Users could not care less - they never have to touch an SMA. The "full" Infiniband stack is very lightweight and already includes an SMA, and it already includes ib_umad module which makes it possible to implement subnet management in userspace should you want to. -- Michael S.
