Typical organization of an OpenCL application
OpenCL : Open Computing Language

Depending on the problem to be addressed, it is first necessary to define the size of the NDRange in order to size the architecture to be used, i.e. the number of work-items and their division into work-groups running in parallel.

An OpenCL application is organized as follows (table 5 and figure 16 ).

Recall that the host application stacks a series of commands. Commands are stacked in an orderly fashion, but can be executed in either order or disorder.
