My particular niche tech-obsession is looking at how things scale. I am patiently waiting to get my hands on my E16's so that I can rerun shodruck's demo. I'm sure there are others who would try to tinker with it to squeeze even more juice out of the code, with tricks like ensuring code and data alignment, etc. Loads of fun to be had.
We now have two excellent early demos of what a E16 can do. So what would these demos look like running on an E64?
@Andreas: You now have shodruck's open source code, can you run these demos in your labs on an E64 board, over a longer range of active cores?
Dreaming of the E64, and looking at the 'near linearity' of the Mandelbrot demo on 1, 4, 16 cores, my guess is that we'd see quite a droop in the speed up graph as the workload is spread over the range up to 64 cores. That's inevitable (Amdahl seriality, etc), but the speed-up results should still be impressive.
Or call me crazy perhaps - if you haven't got the time - why not ship one of the E64 boards to Shodruck. I'm sure he'll make very good use of one.

I don't know the meaning of the name either. Just an inspiration...
