Cos 318: operating systems processes and threads kai li computer science department princeton university ( cs.princeton.edu courses cos318 ). If one thread in a process blocks (e.g., on i o), the os knows about it, and can run another thread (from that process or others) on that core. Threads represent the actual processing of the code. a process has its own system registers and memory stack which helps them in executing threads. threads are sometimes called lightweight processes. the graphic below shows a process with a single thread within it: single thread in a process threads are very helpful in today's multi tasking world.

We can have concurrency within a single process using threads: independent execution sequences within a single process. Processes and threads chapter 3 and 4 operating systems: internals and design principles, 9 e william stallings. What is an operating system? a program which controls the execution of all other programs (applications). acts as an intermediary between the user(s) and the computer. extensibility. similar to a government. . . controls all execution. multiplexes resources between applications. abstracts away from complexity. typically also have some libraries. How do user and kernel threads map into each other? many user level threads mapped to single kernel thread. used on systems that do not support kernel threads. each user level thread maps to kernel thread. does fork() duplicate only the calling thread or all threads?.
