You're assuming the use of Windows; I'm speaking more in general terms.
That includes X-windows. Other than people running servers, most stuff
here by average users, running user aps or 3D games. Even the most
important research program I can think of is modest in memory
requirements - just accurate multi-precision math.
Running HPL on a modern x86 processor tends to
disagree with you
(though
on the recent 6+ core chips, memory wait can be significant if you're
pushing all the cores).
You work in a supercomputer environment...you're running far more modern
stuff than most of the rest of the world. I'm talking about the
HT/Replay chips. Think 2.4GHz 32-bit Pentiums. Those are the boxes that
I see everywhere. -Dave
