Yes that is accurate.

I think it depends on the architecture and is true right now but not in
the (perhaps near term) future. In the current architectures (mthca,
ipath), perfquery accomplishes almost the same thing as ibping. I'm not
so sure that is the case for ehca.

I can envision component failures where something like this is useful.

It may not be an oddball debugging scenario. One man's oddball is
