Thread Library

This thread library is a kernel library on Unix written in C++. This library uses timer interrupts, atomicity, and a FIFO scheduling order. It can be initialized with multiple CPUs.

My partner and I were responsible for implementing the following functionality for the following objects:

• CPU:

  • Constructor, destructor

• Thread:

  • Constructor, destructor

  • void join(): waits for the thread to finish

  • void yield(): yields the CPU to the next thread

• Mutex:

  • Constructor, destructor

  • void lock(): locks the mutex

  • void unlock(): unlocks the mutex

• Condition Variable:

  • Constructor, destructor

  • void wait(mutex &): waits on a condition variable with the associated mutex

  • void signal(): wakes up one thread associated with the condition variable

  • void broadcast(): akes up all threads associated with the condition variable

This project was completed for my operating systems class and is stored in a private GitHub. If you would like to see the code for this project, please contact me.
