17 Questions
What is the advantage of a server creating a new thread to service a request compared to creating a new process?
It is cheaper than process creation and has lower overhead
What is the primary benefit of multithreading in interactive applications?
Improved responsiveness
How do processes share resources?
Through shared memory and message passing
What is a benefit of multithreading for an application?
It allows the application to share code and data
What is a challenge of multicore programming?
Dividing activities among multiple cores
What is the primary advantage of concurrency in a system?
It allows the system to perform multiple tasks simultaneously
What is the primary reason why process creation is not suitable for a busy web server?
It is not efficient in terms of resource usage
What is the main advantage of using multiple threads in a web server?
It enables the server to service multiple clients concurrently
What is the primary motivation for using multithreading in modern applications?
To implement multiple tasks within an application
What is the main difference between process creation and thread creation?
Process creation is heavy-weight, while thread creation is light-weight
What is the main advantage of using a multithreaded server architecture?
It enables the server to service multiple clients concurrently
Why is it generally more efficient to use one process that contains multiple threads?
Because the new process will perform the same tasks as the existing process
What is the primary difference between data parallelism and task parallelism?
Data parallelism distributes data across multiple cores, whereas task parallelism distributes tasks across multiple cores.
What does Amdahl's Law measure?
The potential performance gain from adding additional computing cores to an application with both serial and parallel components.
What is the significance of the variable S in Amdahl's Law?
It represents the portion of the application that must be performed serially.
What would be the result of running an application with 75% parallel and 25% serial components on a system with two processing cores?
The application would achieve a speedup of 1.25.
What is the primary advantage of using multiple cores in a system?
It enables parallel execution of applications, leading to increased performance.
