第三届中国 Rust 开发者大会 Use Rust to Develop the Decentralized Open Data Application Mike Tang daogangtang@gmail.com @daogangtang 2023-06-08 ➔ 裁员 ➔ 互联网格局定型 ➔ 平台倒闭，数据丢失 这是一个什么时代？ 互联网的终局 创业 -> 种子 open data? The business of the closed data model has been at the end. A New Proposal: Open Data Application The Road to Open Web ➔ From the user side, it looks like just the traditional Internet app “EightFish is a development framework (maybe the first one) for the Open Data Application (ODA), implementing the Open Data Application Model (ODAM). The theory of the ODA and ODAM is located here. In short

If the data is not structured in a cache friendly way, the CPU will have to wait. What if the application needs fast access to neighboring data, rather than elements in a row, or must transverse the data a 32768 x 32768 matrix transpose. • Another example of using data grouping is when running an application that uses a large matrix multiply function. Using a combination of new ordering and the Intel achieved due to cache locality. Taking advantage of cache lines will greatly speed up performance of application codes. https://insidehpc.com/2015/10/morton-ordering/ 第 9 章：多核下的缓存 伪共享（ false sharing ） •
