"It is important to note that this does NOT mean Larrabee hardware is
also going to find its way to these developers hands yet; the software is
essentially a Larrabee emulator that compiles and "runs" the code on the
primary system CPU. The current setup will allow developers to start
playing with as much as a 16-wide SIMD and to see how the programming model
for Larrabee is similar to, and differs, from traditional x86 programming."
