Boss and Workers Pattern

This set of flashcards covers key concepts related to the boss and workers pattern in multithreading applications, including definitions and implications of the processes described in the lecture.

Boss Worker Pattern

A threading pattern characterized by one boss thread assigning tasks to multiple worker threads.

Throughput

The amount of work completed in a given time period; in this context, it is affected by the boss's performance.

Order Processing Steps

The sequence of tasks that must be performed to complete an order: accept, parse, cut, paint, assemble, and ship.

Signaling Workers

The process where the boss keeps track of which workers are free and assigns them tasks accordingly.

Producer Consumer Queue

A model where the boss (producer) puts work requests into a queue for workers (consumers) to pick up.

Synchronization

The coordination between threads to ensure that they access shared resources, like a queue, in a controlled manner.

Handshake

A form of communication where the boss waits for a particular worker to confirm receipt of an order before proceeding.

Shared Queue

A data structure used to hold tasks that require coordinated access from multiple worker threads.

Negative Aspect of Signaled Workers

The boss must manage task assignments for each worker, potentially reducing system throughput.

Positive Aspect of Shared Queue

The boss does not need to track individual worker status or wait for confirmations, improving efficiency.

Impact of Boss's Efficiency

The overall system performance depends on how efficiently the boss thread can manage incoming orders.
