Samsung's Processing-in-Memory (PIM)

So you basically dispose of cache for the memory region used? I wonder what the offsets of the cache misses is going to be in practice (the article addresses it but there is no solution/impact given by samsung).

Interesting that Samsung still pursues PIM. IIRC they had a paper in ISCA21 or 22 where they showed HBM2 module with PIM, which back then impressed me quite a lot.

That being said, I am not sure what’s the killer application for this technology, and without such application adoption is unlikely.

In-memory computation was already possible with regular DRAM: https://news.ycombinator.com/item?id=22712811

Add a new set of CPU instructions like “rep macb”

...and it's been long enough now, that I can say there was an effort to implement this on standard x86 memory controllers and have the existing string instructions do so, back in the days of SDR SDRAM, but the tradeoffs weren't (yet) in favour.

If we could buy a 64gb stick and run a 32b model with 30tps on it. This could sell
