system - how can you tell the requirements for you program?

Question

I'm a beginner at programming and I was wondering how programmers found out what the system requirements were for their program. I know about RAM and the OS needed to run it, but how about the CPU (or gpu if it is needed for the program.)

Answer 1

最简单/更便宜的方法：在虚拟机中运行您的程序，然后增加和减少内存和处理，以找出令人满意的使用的最低要求。

Answer 2

检查任务管理器的统计数据并明智地决定。
