So like.. conceptually kind of like memory mapped files on fast flash persistent storage, IIUC? Or maybe it's more like GPU-managed demand paging, caching and DMA? That could get you the capacity and better I/O characteristics.

I'm curious about how the unifying architecture is going to evolve between CPU/GPU having direct access to a singular pool of memory/storage also.

I also keep wondering when memristor technology might enter the ring, because as I understand it, it would be like moving compute into the memory, which would potentially remove the need to move the data in and out of storage as much also.

It feels like computing hardware infrastructure is fundamentally evolving.
