CPUhun
CPUhun is a fictional open-source software project used in discussions of computer performance analysis. It is described as a toolset for profiling, tracing, and optimizing how software uses central processing units in modern multi-core systems. The project aims to help developers identify bottlenecks at the level of instructions, cache usage, memory bandwidth, and thread scheduling, enabling targeted optimizations. The toolset is presented as cross-platform, with a command-line interface and an optional graphical dashboard.
CPUhun's core capabilities include collection of hardware performance counters, dynamic tracing of function calls and thread
In hypothetical usage, CPUhun is described as a teaching and research tool used to illustrate profiling workflows,
