世面上将c++性能优化的书其实不少了,但是很多都停留在架构、算法、数据结构层面,大都是些老生常谈了。而从语言本身、操作系统、硬件层面系统阐述性能优化的技术书则少了很多。而《optimizing software in c++》…
异常和错误处理 c++中通过try catch捕获异常。异常处理旨在检测很少发生的错误,并以一种优雅的方式从错误条件中恢复 虽然程序运行时没有错误,但是异常处理仍需要额外的时间,花销多少取决于编译器实现。 如果你的应用程序不需要异常处理,那么应该禁用它,以便使代码更小、更高效。你可以通过关闭编译器中的异常处理选项来...

Based on the analysis of the Go community's optimization solution for floating-point variable comparison on the ARM64 platform, this document describes how to add compilation rules to make the compiler more intelligent and obtain better instruction combinations to improve the software execution speed. ...
technologies such as unified NFV resource pool scheduling, on-demand dynamic orchestration of microservices, elastic tidal scaling, and software performance improvement. This solution consumes 30% less power per bit than traditional equipment, reducing customers' annual CAPEX on hardware and energy ...
In fact, the applications you've already written for the Tablet PC should run without a hitch. However, there are some differences to keep in mind when writing new software for UMPC devices or when tweaking your current software to provide a better UMPC experience. First, a UMPC has a ...

With that the Software Engineering Institute (SEI) pays tribute to the fact that, after the process has been defined, higher process maturity, and with that higher product maturity, can only be achieved by improving and optimizing the life-cycle process itself. In the last three years, we ...
Persistent VDI is, at the basic level, a VM that saves operating system state in between restarts. Other software layers of the VDI solution provide the users easy and seamless access to their assigned VMs, often with a single sign-on solution. ...
