该程序用来计算 CPU 核心间通信延迟.
具体方式为, 将两个线程固定在两个不同的 CPU 核心上, 通过CPU缓存一致性协议, 让线程执行一系列比较交换操作来测量延迟.
该 fork 旨在提升程序的易用性并收集更多 CPU benckmark 数据来进行展示.
*** 注意, 由于 MacOS 已经移除了相关接口, 导致本程序依赖的 core_affinity 库无法在 MacOS 系统上将线程绑定到特定的核心上运行, 同时也无法在运行时获取当前核心 ID. 因此本程序在MacOS 上的测试结果严格来说是无效的 (可能都被调度到了相同的一个或几个核心上). 建议 Mac 用户安装 Linux 系统进行测试 ***
如何运行:
请到 https://github.com/KCORES/core-to-core-latency-plus/releases 下载.
下载完毕后, Linux 系统运行:
core-to-core-latency-plus 5000 300 -b 1 --upload
Windows 系统需要打开 CMD, cd 到文件所在目录并运行:
core-to-core-latency-plus.exe 5000 300 -b 1 --upload
注意, --upload 选项会上传您的 benchmark 结果到 https://core-to-core-latency.kcores.com.
您可以根据上传完毕后生成的链接来查看您的结果并生成 heapmap.
由于 history benchmark 结果过大 (results 文件夹内的内容生成 jupyter notebook 会达到 170MB), 因此强烈建议上传 benchmark 结果到该网站并实时生成 heapmap. 如果您需要手动查看历史结果可以访问 History Results 并安装 python 相关环境后, 使用 jupyter notebook 打开并生成.
$ cargo install core-to-core-latency-plus
$ core-to-core-latency-plus 5000 300 -b 1 --upload

- 按照延迟中间值进行排序, 越小越好
