HP has demonstrated a working prototype of their revised “The Machine” architecture. For those not familiar with the concept this is essentially a scalable distributed computer that is no longer constrained to a single chassis, you can have a room full of “nodes” of the system each containing an on board processor, RAM and is connected to a fiber accessible storage that is essentially persistent RAM and all of this communicates with the storage and with each other as if it was a single computer.
In this talk from Feb they mention the first system they want to build as having 80 processors and 320 TB of Fiber accessible RAM (not sure what else to call it honestly). More info on how the system works at the hardware/software level is also discussed.
Also it goes without saying that this will not change what an average person buys or uses, it will only be used in the server realm for the next decade at least.
