User level threads
Budget: ₹1,500 – ₹12,500 INR
You will implement a simplified version of many-to-one user level threads in the form of a library
called Simple Threads.
In the many-to-one model for user level threads, all threads execute on the same kernel thread. As
there is only one kernel-level thread associated with the process (the process containing threads is
represented by a single context within the kernel), only one user-level thread may run at a time.
Your thread manager will include a preemptive round-robin scheduler. If a thread does not yield
during its time-slice, it will be preempted and one of the other ready threads will be resumed. The
preempted and resumed threads should change state accordingly.
You will also implement thread synchronization and demonstrate that it works as expected. Implement the
equivalent of pthread mutex lock, pthread mutex unlock, and pthread join, and pthread barrier wait – call them
uthread mutex lock, uthread mutex unlock, uthread join, and uthread barrier wait – in your user threads
