It is less the problem of the instruction set but the
architecture. PIM means small memory grains, which doesn't allow you
to use lavish data structures (like voxels). On the other hand, you
can hardwire the forcefield engine in silicon. Finding nearest
neighbours, accelerating DPMTA (or use voxels for electrostatic maps),
integrating, etc.
I doubt IBM has something as a advanced in mind, though. The machine
would be too special-purpose then.

I've looked at a massively parallel (kBit wide bus) PIM architecture
for neural applictions a few years back, there are orders of magnitude
for acceleration there.
I'm glad such architectures are finally moving in the mainstream (see
Playstation 2 for a most prominent example).
