<p>> load all the LLM parameters or KV cache in RAM and exclusively let it perform GEMV and let it rip.<p>Won’t you have a bunch of extra reads/writes via the CPU because these DIMMs won’t be able to compute matrix multiplications?</p>

<p>Rollie calculation, like the online softmax in FA, implies a centralized computing unit that does the compute and stores the intermediate results in its registers. With PIM you have no centralized compute unit, you have a bunch of memory, and a bunch of MACs all over the place.<p>How would you do map-reduce across multiple DIMMs w/o extra reads/writes?<p>PIM implies some sort of distributed compute, which can work for some cases, but I am not sure LLMs are one of them.</p>

<p>How exactly the map-reduce will happen though? Won’t you need to do it host-side, or make a lot of reads and writes?<p>Also, doesn’t it mean that you forgo batching?</p>

<p>> You could run MACs directly in RAM<p>Sure, MACs are nice. However, unless there other, PIM-specific/optimal, algorithms, regular matrix multiplication algorithms like tiling-based won’t work here I think — how would the tile be shared? By doing read/write all the time?</p>

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

<p>> Sure, but not the way West conducted it, by going and killing generations of people.<p>Ridiculous statement. China is doing it today — uighurs are actively erased bit by bit.<p>> Look at India, before British colonization they accounted for almost 25% GDP of the world (~1700s), now it is around 3-4%<p>This statement is rooted in “zero sum” logic, and based on the assumption that without colonization India should have stayed with its 25% or more share. Hypotheticals are hypotheticals, and nothing more.<p>> You keep defending the West,<p>I’m not defending anyone. I find it ridiculous that you are so high on “the west is bad, China good” horse and completely oblivious to so many things that China does, which are objectively worse.</p>

<p>China is imperialist as any other country.

<p>> I'd call it a whataboutism<p>I would say that saying about anything “whataboutism” is a cheap way out.<p>China does industrial espionage for the same end goals as American companies work on new things: market domination.

<p>> I wonder just how different their processes really are<p>Night and day.<p>Apples has in-house silicon dev groups starting (at least) 2008 w/ acquisition of PA semi for their low power CPUs, followed by the acquisition of Anobit in 2012(?). Apple does their own architecture, microarchitecture, etc, full cycle development.<p>Apple licenses ISA, not designs.</p>
