The coherency is not enough to be able to write concurrent programs and thus comes along a cache consistency model.
Its primary application has been Model checking of concurrent programs, to find defects such as data races and deadlocks.
The differences between sequential and concurrent programs lead to the differences in their testing strategies.
To make the concurrent programs repeatable, an external scheduler is used.
In order to write correct concurrent programs, programmers must be aware of the exact consistency model that is employed by their systems.
A concurrent program is an abstraction of cooperating processes suitable for formal treatment and study.
The primitives are used to construct the concurrent program.
Correctness of the concurrent program can only be shown using a mathematical argument.
That way, viewers can keep track of several concurrent programs in their area while watching one program on the main portion of the screen.
There are approximately 1,000 concurrent programmes at any one point in time.
