Question
Explain the concept of thread priorities and how they affect thread scheduling. Discuss potential issues with thread priority inversion.
Expert Solution
Step 1: Conceptual Introduction:
Thread priorities are a fundamental aspect of multithreading in computer science.
In a multi threaded program, threads are independent units of execution, and thread priorities determine the order in which these threads are scheduled to run on a CPU core.
Thread priority levels are assigned to threads, and the operating system's scheduler uses these priorities to allocate CPU time.
Higher-priority threads are given preference over lower-priority threads.
