NCS: Multi-Threaded Control Systems
| Prev: Spread | Course Home | Next: Alice Follow |
Early control systems used carefully synchronized control loops to insure that control processes ran at a fixed clock cycle and with predictable timing. Modern multi-threaded control environments use much looser timing models and provide non-deterministic execution, but provide advantages in terms of programming flexibility and processor utilization. In this lecture we focus on the Pthreads programming environment, which provides a standardized API for managing process threads and mutexes (to resolve data access conflicts).

Reading
POSIX Threads Programming, Lawrence Livermore National Laboratory. 2006. This tutorial provides an introduction to Pthreads, the standard implementation of threads under linux. It's a pretty quick read, with examples of the code and pretty good descriptions of the basic pthreads functionality.
