If you need to create dummy CPU load on a machine, you can consider building your own CPU stress tool.For basic needs, a simple one-liner in C can be used to create 100% CPU load on one or multiple cores.To create 100% CPU load on one core, you can use the code: 'int main() { while (1) {} }'To create 100% CPU load on multiple cores, you can use a multi-threaded approach with POSIX threads.
