'''''Multithreading''''' computers have hardware support to efficiently execute multiple [[thread (computer science)|threads]].

The '''''Multithreading''''' paradigm become more popular as efforts to further exploit [[instruction level parallelism]] have stalled since the late-1990s. TheThis allowed the concept of ''Throughput computing'' isto thatreemerge to prominence from the more speciailized field of [[transaction processing]]:
* evenEven though it is very difficult to further speed up a single thread or single program, most computer systems are actually multi-tasking among multiple threads or programs.
* Techniques that would allow speedup of the overall system throughput of all tasks would be a meaningful performance gain.

The two major techniques for ''throughput computing'' are [[multiprocessing]] and multithreading.

Some criticism of multithreading include:
