PDF-Parallel Threads Tutorial Due to the nature of executi

For most simple program executions most thread are executed virtually instantaneously however there may be some instances where the behavior of parallel threads may introduce unforeseen timing errors Parallel threads are concurrent processes that ex. Single and Multithreaded Processes. Benefits. Responsiveness. A program can continue running even if part of it is blocked or waiting for long I/O. Important for user interfaces. Resource Sharing. Easier to share resources between threads (shared memory) compared to between processes. David . Monismith. Based on notes from . Introduction to Parallel Programming. 2. nd. Edition by .

Sometimes a program needs to do multiple tasks concurrently. Example: Word processor . Tasks include: Display graphics, respond to keystrokes from the user, and perform spelling and grammar checking.
