Questions and Answers

In computer architecture, what is multithreading and how does it differ from multiprocessing?

Multithreading is the ability of a CPU to provide multiple threads of execution concurrently, sharing the resources of a single or multiple cores. This differs from multiprocessing, where multiple complete processing units are included in one or more cores.

What resources do threads share in a multithreaded application?

Threads in a multithreaded application share resources such as computing units, CPU caches, and the translation lookaside buffer (TLB).

How does multithreading aim to increase utilization of a single core?

Multithreading aims to increase utilization of a single core by using thread-level parallelism, as well as instruction-level parallelism.

Why has the multithreading paradigm become more popular since the late 1990s?

<p>Efforts to further exploit instruction-level parallelism have stalled, allowing the concept of throughput computing to re-emerge. Most computer systems are multitasking among multiple threads or programs, and techniques that improve the throughput of all tasks result in overall performance gains.</p> Signup and view all the answers

What is the relationship between multithreading and multiprocessing in modern systems architectures?

<p>In modern systems architectures, the two techniques are complementary and are combined in nearly all systems with multiple multithreading CPUs and with CPUs with multiple multithreading cores.</p> Signup and view all the answers
