Programmers Stack Exchange is a question and answer site for professional programmers interested in conceptual questions about software development. It's 100% free, no registration required.

Some months ago I stumbled across a video on the internet of somebody giving a very good talk on the impact of memory access latency on the execution of programs. I'm trying to find the video again; maybe you know what video I mean and were I can find it.

This is what I remember about the talk/video:

  • I don't remember the title and it may have been broader, but the talk was a lot about impact of memory access latency in modern processors on program execution.
  • The talk was in English and most likely the location was in America.
  • The speaker was very knowledgeable about the topic, but the talk was in an informal setting (not a conference presentation or university lecture). I think the speaker was known to the audience and may even have been famous (I don't remember)
  • The audience may have been a computer club / group of a local community or company (but I don't remember for sure)

Maybe it was Ulrich Drepper talking? He has a great paper called What every programmer should know about memory (lwn.net/Articles/250967). –  Vitor Jun 21 '11 at 2:32

This sounds vaguely like one of Herb Sutter's talks ("The free lunch is over"). I'm not sure where you can find a video of that anymore though. –  Jerry Coffin Jun 21 '11 at 2:50
    
@Jerry Herb Sutter turned out the right direction, different talk though: Machine Architecture: Things Your Programming Language Never Told You –  user12889 Jun 21 '11 at 5:22
    
Oops -- yup, that's the one I was thinking of, but my memory came up with the wrong name. Sorry 'bout that. –  Jerry Coffin Jun 21 '11 at 5:25

Found the answer thanks to Jerry Coffin's comments:

Herb Sutter: "Machine Architecture: Things Your Programming Language Never Told You"

Slides and video available through http://www.gotw.ca/. The main link is dead, the links in () are still good.
