One-of-a-would be-to-adaptively sleep the threads, similarly as video playback is do in Java. If you know want 50% core utilization, the your algorithm should sleep approximately 0.5 seconds-potentially distrib Uted within a second (e.g. 0.25 sec computation, 0.25 sec sleep, e.t.c.).

In addition, the CPU usage seen from the JVISUALVM is the total CPU utilization on the machine, if the PC is 4 cores, 50% CPU, showing 12.5%, 100% CPU, showing 25%.
