You don't hate to say it at all. It's probably standard operating procedure with you. You (for whatever reason), with no presented identity or credentials, feel entitled to set the terms of the debate. The world is full of people like you. When I was teaching, students would come in with their attempt at the homework and insist that I show that what they were doing wrong. My position was that it was my job to show them how to do it right. You've brought your homework, and your conclusions, and you want me to show you what you are doing wrong.

Now that you've got me going, I'm interested in just what it is that Linpack is actually doing, just as I am interested in what it is that the UCSD paper is actually doing. In both cases, it may take me a while to satisfy myself. You can *always* invent low bandwidth calculations that do actually keep the processors busy. That doesn't mean that you have a good algorithm. If you burden the FPU's with enough busy work, you can always artificially scale the work that the FPU's have to do to the bandwidth that is available. I strongly suspect that that's what the UCSD paper is doing, and I'm beginning to wonder if Linpack doesn't fall into the same class. Notice that I don't claim to have presented anything more than a strong hunch, but I have more confidence in my own hunches than I do in your judgment.

Did you ever, by the way, hear the story about UCSD and small-scale fusion reactors? I know (or knew; some of them may be dead by now) some of *those* crackpots.
