IANoWayAFabExpert but I don't think so. I understand the cost of transferring signals between chiplets is high, so I don't see this as a way forward except for when the cost of such a transfer can be amortised by handing over a smallish packet of work (in terms of data size) that needs a large quantity of CPU, and a smallish amount of data to transfer back. So coarse grained only. Not suitable for general computation anyway.
IMO only. Not my area. Pinch of salt etc.
