explicit parallelism


Also found in: Wikipedia.

explicit parallelism

A feature of a programming language for a parallel processing system which allows or forces the programmer to annotate his program to indicate which parts should be executed as independent parallel tasks. This is obviously more work for the programmer than a system with implicit parallelism (where the system decides automatically which parts to run in parallel) but may allow higher performance.

Some might object to the explicit parallelism "Mondial 2010" creates between homosexuality and transborder traffic, yet the film doesn't come across as an ad for political normalization with Zionist occupation.
The main characteristics of this class are explicit parallelism and implied synchronization of document parts.
Alternatively, we could note that the machinery required for explicit parallelism is always the same, no matter what the base language: to get parallelism, we must be able to create and coordinate simultaneous execution threads.
c) sidestep the whole issue, by using sophisticated compiler or runtime technology to achieve parallel execution of programs that lack explicit parallelism.
