9. Chapter 5 Concurrency: Mutual Exclusion and Synchronization Sections 5.1 to 5.7 Race condition, critical section, and mutual exclusion On a uniprocessor system, interrupt is the root of all evil Hardware solutions: disable/enable interrupts, test&set, swap Semaphore: binary and counting Monitor and condition variables Bounded buffer producer/consumer problem: Both mutex and synchronization Message passing: send/receive, blocking/nonblocking Reader and writer problem
