LFCS: A $99 supercomputer

The Epiphany architecture is more like a GPU; an array of simple cores with small local memories and shared memory bus.

There's no denying that having lots of cores in a single package is going to lead to a certain style of architecture, but could you clarify what you mean by "like a GPU"? Looking at the instruction set for, say, the AMD R700 (PDF), it's quite a different animal from that of the Epiphany. Certainly, the latter has memory instructions that look a lot more general purpose than those of the R700.
