Complementary Programs for course "Linux Kernel Internals"

This distribution is a collection of programs that are generally unrelated, except in that they all deal with the concurrent programming. The main purpose of these programs is to be illustrative and educational.

Project Listing

  • Coroutine
    • tinync: A tiny nc implementation using coroutine.
    • fiber: A user-level thread (fiber) using clone system call.
    • preempt_sched: A preemptive userspace multitasking based on a SIGALRM signal.
  • Multi-threading Paradigms
    • tpool: A lightweight thread pool.
  • Producer–consumer problem
    • spmc: A concurrent single-producer/multiple-consumer queue.
    • mpsc: An unbounded lockless single-consumer/multiple-producer FIFO queue.
    • mpmc: A multiple-producer/multiple-consumer (MPMC) queue.
    • channel: A Linux futex based Go channel implementation.
  • Lock-Free Data Structure
    • ringbuffer: A lock-less ring buffer.
    • ringbuf_shm: An optimized lock-free ring buffer with shared memory.
    • mbus: A concurrent message bus.
  • Synchronization
    • qsbr: An implementation of Quiescent state based reclamation (QSBR).
    • rcu_list: A concurrent linked list utilizing the simplified RCU algorithm.
    • rcu_queue: An efficient concurrent queue based on QSBR.
  • Applications
    • httpd: A multi-threaded web server.
    • map-reduce: word counting using MapReduce.
    • redirect: An I/O multiplexer to monitor stdin redirect using timerfd and epoll.
