Hello you fine Internet folks,Today we're at Hot Chips 2026! We join IBM to talk about their just revealed Dual-ISA z/ architecture + ARM design with Christian Zoellin, the Core Design Team Leader and Christian Jacobi, the CTO of Systems Development!Hope…

Memory expansion has been attractive for years, and is more relevant than ever because ML models have an insatiable appetite for memory capacity. In response, XCENA has worked with Samsung to create a CXL memory expansion device that can also host SSDs and…

society […] (countable) The sum total of all voluntary interrelations between individuals. — https://en.wiktionary.org/wiki/society (retrieved on 2026-08-30) (I’m going to use the shorthand “I received” to mean “I was a participant in a conversation in which…

JSON is a standard format for data interchange. It is effectively a tiny subset of JavaScript made of objects and arrays. It looks as follows {"key":1, "text":[1.0,2.0]}. Many programming languages include a JSON library in their standard libraries: C#, Go…

In-memory compute has been an attractive proposition for many years because compute within a memory chip can exploit its higher internal bandwidth. Additionally, in-memory compute avoids the long latency path between DRAM and traditional compute cores. At…

最近尝试用 LLM 进行一些知识的学习，也会在博客记录一些学习的过程，但发现抛开代码后， LLM 的回答的用词有时候非常奇怪，甚至有些不符合人类的表达习惯。 原理 我们以 DeepSeek v4 Flash 为例，来看看它的模型结构，其他 Transformer 模型的结构也大同小异： flowchart TB IN(["input_ids"]) --> EMB["embed 输入词表&LTbr/>129,280 × 4,096"] EMB --> BLK["Block × 43&LTbr/>MLA 稀疏注意力…

This website contains a preview of how Intel intends to document and present the Intel® Architecture in the future. Our goal is a specification that is more accurate and accessible. We would like to receive feedback on how well we meet this goal before we…

Hello you fine Internet folks,At Hot Chips, Intel talked a bit more about their upcoming Datacenter GPU codenamed Crescent Island. Crescent Island’s party piece is the ultra-high memory capacity curtesy of the LPDDR5X memory subsystem. Making Room for Whales…

背景 最近拿到了一台 4 卡 RTX 4090 的机器，但用的是一代至强可扩展（Skylake）+ 技嘉 C621-WD12 主板。我们直接把显卡装上虽然可以使用，但是缺少了 P2P 功能对 LLM 推理跑 TP 不友好，因此我进行了一番折腾。 Resizable Bar 首先，这个主板的 BIOS 默认甚至打不开 Above 4GB Decoding，这意味着所有 PCIe Bar 都会被分配在 Sub 4GB 物理地址空间，而我们一张卡的显存都有 24G，那自然不可能被分配出来。 后来让 5.6 Sol…
