DefinitionGPGPU is a technique that applies the GPU's ability to carry out huge numbers of calculations at once to general-purpose computing beyond graphics.
ExplanationWork that repeats the same form of calculation an enormous number of times, such as training in machine learning or scientific computing, finishes quickly when split across the GPU's many cores. The name is short for General-Purpose computing on GPU.
AnalogyIt is like taking the big crew gathered to paint a mural all at once and having them split up the tallying of a mountain of paperwork instead. Their strength in numbers stays the same; only the kind of work spreads beyond pictures.
Memory hookIt is GPU with GP (General-Purpose) in front. Those two extra letters mean "for more than graphics".
