I will try to dig up those issue vs IPC papers.

My personal opinion is that we are quickly approaching a rapid law of diminishing returns on ILP (extracting IPC) in any given thread, Amadahl's law is taking over.
Yeah I had epic in mind, since itanium is a 6-issue ľarch to beginn with. and those papers are welcome if it doesn't take to much time to dig them up.
