Pipeline Stages and Processing Models

These flashcards cover key concepts related to processing models, specifically focusing on the Boss Worker and Pipeline models, execution time, and overhead considerations.

Boss Worker Model

A threading model where one thread acts as the boss and multiple threads act as workers to process tasks.

Pipeline Model

A processing model in which tasks are divided into stages, allowing for continuous flow of tasks through different stages.

Threads

The smallest unit of processing that can be scheduled by an operating system.

Execution Time

The total time taken to complete a task or process, including processing and potential overheads.

Overheads

Additional time involved in processing due to factors such as synchronization and data passing among threads.

Synchronization

A mechanism to ensure that two or more concurrent processes or threads can operate safely and without conflicts.

Shared Memory Queues

Data structures used to hold data temporarily while being transferred between multiple threads or processes.

Processing Efficiency

A measure of how effectively a given model or method can complete tasks within a specific timeframe.

Toy Orders

A hypothetical set of tasks used to evaluate the performance of different threading models.

Millisecond (ms)

A unit of time equal to one thousandth of a second.
