Real Critical Section Code and Concepts

Flashcards covering key concepts and terminology related to critical section code and synchronization in multithreading.

Critical Section

A segment of code that accesses shared resources and must not be executed by more than one thread at a time.

Mutex

A mutual exclusion object that prevents multiple threads from accessing a critical section simultaneously.

Predicate

A condition that determines whether a thread can access the critical section.

Condition Variable

A synchronization primitive that enables threads to wait until a particular condition is true.

Wait Statement

A command that causes a thread to wait for a condition to be met, typically associated with a mutex.

Signal

An operation that wakes up one thread waiting on a condition variable.

Broadcast

An operation that wakes up all threads waiting on a condition variable.

Intercritical Section Block

Code blocks used to manage access to shared resources, allowing some operations to proceed concurrently.

Readers-Writers Problem

A classical synchronization problem that involves protecting shared data that can be read by multiple threads but written by only one.

Unlock Operation

An operation that releases a mutex, allowing other threads to access the critical section.
