简要介绍: https://taskflow.github.io/showcase/index.html

1. Taskflow is FREE:
   1. from explicit thread management
   2. from difficult lock mechanism
   3. from daunting class declaration
2. Drop-in Integration:
   1. 只有头文件，方便集成。

motivation

Cookbook » Project Motivation | Taskflow QuickStart

Taskflow addresses a long-standing problem, how can we make it easier for C++ developers to quickly write parallel and heterogeneous programs with high performance scalability and simultaneous high productivity?

分支预测相关_为了克服上述问题,pipeline中引入了branch prediction机制。branch pr-CSDN博客

文章浏览阅读1k次。本文探讨了CPU流水线中的分支预测机制，旨在提高指令执行效率。通过静态和动态预测技术，处理器可以预先判断并执行可能的指令路径。然而，分支预测失败，如在处理无序数组时，会导致性能下降。此外，虚函数调用由于动态联编和查找虚函数表，可能导致分支预测失败，增加性能开销。理解和优化这些机制对于提升程序性能至关重要。
