The vocal cords are sometimes called 'true vocal cords' to distinguish them from the false vocal cords. These are a pair of thick folds of mucous membrane. They sit directly above the true vocal folds, to protect them. They have a very small role in normal speech , but are often used in musical screaming and the death grunt singing style. They are also used in Tuvan throat singing.
The false cords are also called vestibular folds and ventricular folds. They can be seen on the diagram above as "ventricular folds".
Unlike the true vocal cords, the false ones grow back completely when they are removed by surgery.
Parallel computing
Parallel computing is a form of computation in which many instructions are carried out simultaneously (termed "in parallel"), depending on the theory that large problems can often be divided into smaller ones, and then solved concurrently ("in parallel").
There are several different forms of parallel computing:
It has been used for many years, mainly in high-performance computing, with a great increase in its use in recent years, due to the physical constraints preventing frequency scaling. Parallel computing has become the main model in computer architecture, mainly in the form of Multi-core processors. However, in recent years, power consumption by parallel computers has become a concern.
Parallel computers can be classified according to the level at which the hardware supports parallelism—with multi-core and multi-processor computers having multiple processing elements inside a single machine, while clusters, blades, MPPs, and grids use multiple computers to work on the same task.
Parallel computer programs are more difficult to program than sequential ones, because concurrency introduces several new classes of potential software bugs, of which race conditions and dead locks are the most common. however many parallel programming languages have been created to simplify parallel computers programming. But still communication and synchronization between the different subtasks is difficult while achieving good parallel program performance.
