CXL在这里的作用可以理解为External cache coherent agent，一个带CC的iMC，带宽肯定比NUMA高，但是这个工作只提升了18%，他们的策略是用PMU collect data，然后冷热load 和flush，给个temperature的grading，个人觉得肯定有page coloring那种优秀的算法搞定这件事，比这个数高。

Application-Informed Kernel Synchronization Primitives
一个runtime dynamic profiling/loading guided lock primitive，可以同时兼顾到high/no lock contention的情况。

IOring Windows at first sight and migration to `monoio`
最近在和LemonHX一起写个跨平台下载器，想要的是个延时确定的协程调度器，然后我们就看上了字节开源的monoio，准备贡献一波Windows部分。
主要需要跨平台抽象的部分已经写好了, GAT 刚进主线, 其实感觉贡献这个更经济一点. 字节内好像也没有开始用这个, 只是做了点测试.
Twizzler: a Data-Centric OS for Non-Volatile Memory
A Distributed NVM modeled OS runtime for the arrangement of NVM data structure that
- Does not require explicit (un)loading
- Less serialization (Context available persistent ptr to reduce memcpy).
- Has basic support for security/ share/ crash atomicity

OSDI/ATC22 attedency
ATC的容量大改是OSDI的1.5倍吧，有两个track两天的样子，ATC的工业界浓度更高一些，OSDI会选出那种新颖的方向，真的有点像奥斯卡的选奖逻辑。
ISCA 22 Attendancy
如Mingyu大大所说体系结构的人不那么重视绝对值和相对值，系统会会quesiton结果和设计。这次花了200🔪线上，可惜没能在这之前拿到签证现场去开会。不过还是能听听songshixin和ucsc教体系结构老师的作品，还有yanmengjia yyds。同时也见到了Mingyu Gao的新的domain specific的hw-sw codesign。不过大佬的talk倒真的没啥意思，都是鸡汤或者论文精炼和insight，像在上研究生课。

CXL disaggregation because:
- Memory inefficiency: s platform-level memory stranding
- Current cloud vendor try on memory disaggregation: require no modifications to
customer workloads or the guest OS./ the system
must be compatible with virtualization acceleration techniques/ the system must be available as
commodity hardware.
