Hi, I want to develop a program that runs along with another program on the same physical CPU (as two hyperthreads). I wonder how the CPU hyperthreading engine behaves if both programs are running and using the same CPU resource. It means that there is no idle time to utilize and the CPU has to choose one program to execute.
