parallelize

Phoneticspar·al·lelize

/ˈpæɹəlɛlaɪz/

Definition

v. to change a task so that a computer can do many parts of it at the same time instead of one by one.

v. to adapt a computational task or algorithm so that its components can be executed simultaneously across multiple processors.

Examples

“We need to parallelize the code to make it run faster.”

“The development team spent weeks trying to parallelize the rendering engine to take full advantage of modern multi-core hardware.”

“While it is theoretically possible to parallelize the simulation, the high degree of data dependency between steps often results in significant synchronization overhead.”

Examples
