Pthread is a user-level thread or kernel-level?.Java supports user-level threading i know ,but while doing a project on web- crawling i marked the cpu-utilization in conky(ubuntu) ,both the cores' utilization increased drastically as program ran.I know that in user-level threading kernel is not aware whether a process is multithreaded or not,rather it sees the entire process as a single entity .But in my project i think the dual cores utilization increased because of the threads being scheduled on both the cores.I dont understand how is it possible as the kernel isn't aware of the process thread since it is user-level(java thread).Is it because of jvm implicit feature or java threads are hybrid kind in nature.
