I swore I would avoid this argument but ...

look, there's DSMs and there's DSMs. And there's different types of
applications. I've done a fair number of parallel apps and there are cases
where you can use DSM, and cases where you can't and you use message
passing. I can point to failures with both models.

You want to see failures with DSM, you'll find 'em, because people do
stupid things with them. That doesn't automatically condemn the
technology, it just means it's not universal (what is?).

You want to see a few successes, well, look at my web page and check the
papers.
